How to tell time

Topic Notes

In this lesson, we will learn:

  • A review on saying times of the exact hours (oclock) and parts of the days (in the morning, afternoon, evening or at night)
  • How to say the time by: naming the number of hours and minutes (reading left to right), naming the minutes after the hour, or naming the minutes until the next hour
  • The special ways of saying half and quarter hours: quarter past, quarter to, and half past

Notes:

  • There are many ways to say the time.
  • The simplest way to tell time is when the clock is on an exact hour (i.e. 12:00, 3:00; minute hand is on 12) you can simply call it as the number oclock (ex. 12 oclock, three oclock)
    • We can also say AM and PM as the part of the day instead:
      • in the morning for 6AM to 11:59AM
      • noon for 12:00PM
      • in the afternoon for 12:01PM to 5:00PM
      • in the evening for 5:01PM to 8:00PM
      • at night for 8:01PM to 5:59AM
      • midnight for 12:00AM

  • Saying the hour is easythe focus on the minutes. Three ways to tell time are by writing:
    • \qquad \qquad 1. # hours # minutes
    \qquad \qquad 2. # minutes after/past the hour
    \qquad \qquad 3. # minutes until/to the next hour
    • Ex. 1:35 can be said as (1) one thirty-five, (2) thirty-five minutes after one, or (3) twenty-five minutes to two

  • There are special ways to say half or quarter hours
    • When the minutes are :15 we say quarter after the hour
    • When the minutes are :30 we say half past the hour
    • When the minutes are :45 we say quarter to the next hour
    • Ex. (9:15 is quarter past nine), (6:30 is half past 6), (7:45 is quarter to eight)

  • Although there are many ways to tell the time, there is usually one way that is said more commonly than the rest.
    • The most common way to tell times is summarized in the figure below for the positions of the minute hand on the clock.
    • If the minutes are :01   \, →  \, :30 its common to say the minutes after the hour
    • If the minutes are :31   \, →  \, :59 its common to say the minutes to the next hour

Introduction: Understanding How to Tell Time

Learning to tell time is a fundamental skill that plays a crucial role in our daily lives. Our introduction video serves as an essential starting point for mastering this important ability. By watching this video, learners will gain a solid foundation for understanding the concept of time and its measurement. This lesson will cover various methods of telling time, focusing on both analog and digital clocks. Analog clocks, with their traditional face and hands, provide a visual representation of time passing, while digital clocks offer a straightforward numerical display. By exploring both types, students will develop a comprehensive understanding of time-telling techniques. Whether you're scheduling appointments, catching a bus, or simply managing your day, the ability to tell time accurately is indispensable. This lesson will equip you with the knowledge and skills needed to confidently read and interpret time in various formats, enhancing your daily efficiency and time management capabilities.

Reading Analog and Digital Clocks

Understanding how to read both analog and digital clocks is an essential life skill. Whether you're glancing at a traditional wall clock or checking the time on your smartphone, knowing how to interpret these timepieces accurately is crucial for managing your day effectively.

Let's start with analog clocks. These classic timepieces feature a circular face with numbers arranged around the edge and two or three hands rotating from the center. The shortest hand is the hour hand, which completes one full rotation every 12 hours. The longer hand is the minute hand, making a complete revolution every 60 minutes. Some analog clocks also have a thin, fast-moving second hand.

To read an analog clock, first look at the hour hand. It points to the current hour, but be careful - it moves gradually between hours. Next, check the minute hand. Each number it points to represents five minutes, with the spaces between numbers representing single minutes. For example, when the hour hand is between 3 and 4, and the minute hand points to 6, the time is 3:30.

Digital clocks, on the other hand, display time using numerical digits. Most digital clocks use a 12-hour format, showing hours and minutes separated by a colon. For instance, 3:30 PM would be displayed as 3:30, while 3:30 AM would be shown as 3:30 with an "AM" indicator or in 24-hour format as 03:30.

Reading a digital clock is straightforward. The numbers before the colon represent hours, while those after indicate minutes. Some digital clocks also display seconds after another colon. For example, 14:45:30 in 24-hour format means 2:45 PM and 30 seconds.

Practice is key to mastering clock reading. For analog clocks, start by identifying the hour, then count the minutes in fives as you move clockwise. With digital clocks, remember that 1:00 to 12:59 typically represents AM hours, while 13:00 to 23:59 (or 1:00 PM to 11:59 PM in 12-hour format) indicates PM hours.

Here are some examples to help you practice:

Analog clock: If the hour hand is just past 7 and the minute hand is at 4, the time is 7:20.

Digital clock: 08:45 in 24-hour format is the same as 8:45 AM, while 20:15 equals 8:15 PM.

Remember, the ability to read both analog and digital clocks quickly and accurately is a valuable skill that will serve you well in various aspects of life, from managing your daily schedule to coordinating with others across different time zones.

Different Ways to Tell Time

Telling time is an essential skill in our daily lives, and there are several methods to express the current time. In this section, we'll explore the three main approaches to telling time: naming the number of hours and minutes, declaring minutes past the hour, and stating minutes until the next hour. Each method has its own nuances and is used in different contexts.

The first method involves directly stating the number of hours and minutes. This approach is straightforward and widely used in digital formats. For example, 3:45 would be read as "three forty-five." This method is precise and leaves little room for misinterpretation. It's commonly used in formal settings, schedules, and when exact timing is crucial. Special cases in this method include using "o'clock" when the time is exactly on the hour, such as "three o'clock" for 3:00.

The second method focuses on declaring minutes past the hour. This approach is often used in casual conversation and is particularly common in analog clock reading. For instance, 3:15 would be expressed as "fifteen minutes past three" or more succinctly as "fifteen past three." This method has several special cases that are frequently used. "Quarter past" is used to denote 15 minutes past the hour, as in "quarter past three" for 3:15. Similarly, "half past" indicates 30 minutes past the hour, such as "half past three" for 3:30. These expressions add a conversational flair to time-telling and are deeply ingrained in many English-speaking cultures.

The third method involves stating minutes until the next hour. This approach is particularly useful when the time is closer to the upcoming hour than the current one. For example, 3:50 might be expressed as "ten minutes to four" or simply "ten to four." This method also has a special case: "quarter to" is used to indicate 15 minutes before the hour, as in "quarter to four" for 3:45. This approach can create a sense of anticipation or urgency, especially when discussing upcoming events or deadlines.

Each of these methods has its place in different contexts. The direct hour and minute method is often preferred in professional settings, transportation schedules, and digital displays. The "minutes past" approach is commonly used in everyday conversation and when reading analog clocks. The "minutes to" method is particularly useful when emphasizing the approach of the next hour or when the time is closer to the upcoming hour.

It's worth noting that the choice of method can sometimes depend on regional preferences or personal habits. Some people might consistently use one method, while others switch between them based on the situation. Understanding all three methods ensures clear communication about time across various contexts.

In conclusion, mastering these three methods of telling time - naming hours and minutes directly, declaring minutes past the hour, and stating minutes until the next hour - along with their special cases like "o'clock," "quarter past," "half past," and "quarter to," provides a comprehensive toolkit for expressing time in any situation. Whether you're scheduling a business meeting, catching up with friends, or planning your day, these versatile approaches to telling time ensure that you can communicate clearly and effectively about one of the most fundamental aspects of our daily lives.

Understanding Half and Quarter Hours

Understanding how to read and express half and quarter hours on an analog clock face is an essential skill for both children and adults. This knowledge not only helps in daily timekeeping but also enhances our ability to communicate time effectively. Let's explore the concepts of half hours and quarter hours, and learn how to identify and express these times using both formal and informal language.

On an analog clock face, the hour hand indicates the current hour, while the minute hand shows the minutes. A complete rotation of the minute hand around the clock face represents 60 minutes or one hour. The clock face is divided into 12 equal sections, each representing 5 minutes.

The half hour occurs when the minute hand points to 6, which is exactly halfway around the clock face. This position indicates that 30 minutes have passed since the start of the current hour. For example, when it's half past 2, the hour hand will be between 2 and 3, while the minute hand will point to 6.

To express half hours formally, we can say "half past" followed by the hour. For instance:

  • 2:30 - "Half past two" or "Two thirty"
  • 5:30 - "Half past five" or "Five thirty"

Informally, people often use shortened versions like "half two" or "half five," although this usage can vary depending on regional dialects.

Quarter hours are equally important and occur at 15-minute intervals. There are two quarter-hour positions on a clock face:

  1. The first quarter hour: When the minute hand points to 3, indicating 15 minutes past the hour.
  2. The third quarter hour: When the minute hand points to 9, showing 45 minutes past the hour (or 15 minutes to the next hour).

To express quarter hours formally, we can use the following phrases:

  • 3:15 - "Quarter past three" or "Three fifteen"
  • 3:45 - "Quarter to four" or "Three forty-five"

Informally, people might say "quarter after" instead of "quarter past," or use shortened versions like "quarter three" for 3:15.

When writing these times, it's common to use either the 12-hour format (with AM/PM) or the 24-hour format. For example:

  • 2:30 PM or 14:30
  • 9:15 AM or 09:15
  • 7:45 PM or 19:45

Practice is key to mastering the identification and expression of half and quarter hours. Try setting an analog clock to different times and describing them aloud. This will help reinforce your understanding and improve your time-telling skills.

Remember, while digital clocks are prevalent today, the ability to read an analog clock face and express time using these traditional methods remains a valuable skill. It's particularly useful in situations where you might encounter analog clocks, such as in older buildings, during power outages, or when traveling to places where analog clocks are still common.

By familiarizing yourself with half hours, quarter hours, and their expressions, you'll enhance your time management skills and communicate more effectively about schedules and appointments. Whether you're catching a train, scheduling a meeting, or simply trying to arrive on time for dinner, understanding these time concepts will serve you well in various aspects of daily life.

AM, PM, and Parts of the Day

Understanding the use of AM and PM is essential for accurately telling time and communicating daily schedules. AM, which stands for "ante meridiem" (before midday), refers to the hours from midnight (12:00 AM) to 11:59 AM. PM, meaning "post meridiem" (after midday), covers the period from noon (12:00 PM) to 11:59 PM. This 12-hour clock system helps divide the day into two distinct halves, making it easier for people to distinguish between morning and afternoon hours.

The day is further divided into four main parts: morning, afternoon, evening, and night. Each part corresponds to specific hours and activities. Morning typically starts at sunrise, around 6:00 AM, and lasts until noon (12:00 PM). This is when most people wake up, have breakfast, and begin their daily routines. For example, you might say, "I have a meeting at 9:30 AM" or "Let's meet for coffee at 11:00 in the morning."

Afternoon begins at noon and continues until around 5:00 or 6:00 PM. This part of the day is often associated with lunch breaks, work or school activities, and errands. You might express time during this period as "2:15 PM" or "quarter past two in the afternoon." Evening follows the afternoon, typically starting from 5:00 or 6:00 PM and lasting until around 9:00 or 10:00 PM. This is when many people have dinner, relax, or engage in social activities. For instance, "The movie starts at 7:30 PM" or "We're meeting for dinner at eight in the evening."

Night is generally considered to begin around 9:00 or 10:00 PM and continues until midnight (12:00 AM), after which the cycle starts anew. Late-night hours are often referred to using PM until midnight, such as "11:45 PM," while early morning hours use AM, like "1:30 AM." It's important to note that midnight marks the transition from one day to the next, so 12:00 AM is the start of a new day, not the end of the previous one.

When expressing time, it's common to use both numerical representations and descriptive phrases. For example, "3:00 PM" can be stated as "three o'clock in the afternoon," while "7:00 AM" might be described as "seven in the morning." Understanding these conventions helps in clear communication about time and scheduling, whether for personal plans, business meetings, or travel arrangements.

Common Phrases and Expressions for Telling Time

Understanding and using common time expressions is essential for effective communication in English. These phrases not only help you tell time accurately but also add a natural flow to your conversations. Let's explore some of the most frequently used time expressions and their meanings.

"Quarter to" and "quarter past" are two popular phrases used when telling time. "Quarter to" means 15 minutes before the hour, while "quarter past" indicates 15 minutes after the hour. For example, "It's a quarter to six" means 5:45, and "It's a quarter past three" means 3:15. These expressions are widely used in informal settings and everyday conversations.

Another common phrase is "half past," which means 30 minutes after the hour. For instance, "It's half past three" is equivalent to 3:30. This expression is often preferred over saying "three thirty" in casual conversations.

When it comes to expressing time that falls between these intervals, you can use phrases like "ten past," "twenty to," or "five minutes to." For example, "It's ten past four" means 4:10, "It's twenty to nine" means 8:40, and "It's five minutes to seven" means 6:55.

In addition to these specific phrases, there are more general expressions used to describe approximate times. "Around," "about," and "roughly" are often used when the exact time is not crucial. For instance, "I'll be there around six" or "The meeting starts at about three o'clock."

To practice using these time expressions, try the following exercises:

  1. Convert these digital times to phrases: 2:45, 7:15, 9:30, 11:50, 1:05
  2. Write the digital time for these expressions: "twenty past eight," "quarter to twelve," "half past one," "five to four," "ten past nine"
  3. Create sentences using time expressions to describe your daily routine

Remember, using these informal time phrases adds a natural and conversational tone to your speech. They are commonly used in everyday situations, such as arranging meetups with friends, discussing schedules, or talking about TV show timings. By incorporating these expressions into your vocabulary, you'll sound more fluent and confident when discussing time in English.

As you practice, you'll find that these time expressions become second nature. Don't be afraid to use them in your daily conversations, whether you're asking for the time, setting up appointments, or simply chatting about your day. The more you use these phrases, the more comfortable and natural they will feel.

Introduction to How to Tell Time: Telling the time using "o'clock" and parts of the day

In this guide, we will explore the basics of telling time using the term "o'clock" and understanding the different parts of the day. This will help you accurately say and write the time in various contexts.

Step 1: Understanding the Difference Between Reading and Telling Time

Reading the time involves looking at a clock and interpreting the positions of the hands (in the case of an analog clock) or reading the digits (in the case of a digital clock). Telling the time, however, is about expressing the time verbally or in writing. This includes using specific terms and formats to convey the exact time.

Step 2: Using "O'clock" for Exact Hours

When the minute hand of a clock is on the 12, it indicates the start of a new hour. This is when we use the term "o'clock." For example, if the hour hand is on 12 and the minute hand is on 12, it is 12 o'clock. This format is used for all exact hours:

  • 1:00 - One o'clock
  • 2:00 - Two o'clock
  • 3:00 - Three o'clock
  • 4:00 - Four o'clock
  • 5:00 - Five o'clock
  • 6:00 - Six o'clock
  • 7:00 - Seven o'clock
  • 8:00 - Eight o'clock
  • 9:00 - Nine o'clock
  • 10:00 - Ten o'clock
  • 11:00 - Eleven o'clock
  • 12:00 - Twelve o'clock

The term "o'clock" is derived from the phrase "of the clock," indicating the exact hour with zero minutes.

Step 3: Differentiating AM and PM

To specify whether the time is in the morning or evening, we use AM (ante meridiem) and PM (post meridiem). For example, 12:00 AM is midnight, and 12:00 PM is noon. This distinction helps clarify whether the time is before or after midday.

Step 4: Understanding Parts of the Day

In addition to using AM and PM, we can describe the time of day using phrases that refer to different parts of the day:

  • Morning: From 6:00 AM to 11:59 AM. This is when the sun is rising and the day is beginning.
  • Afternoon: From 12:00 PM to around 5:00 PM. This is the time after midday when the sun is high in the sky.
  • Evening: From around 5:00 PM to 8:00 PM. This is when the sun is setting and the day is winding down.
  • Night: From 8:00 PM to 6:00 AM. This is when it is dark, and the moon and stars are visible.

Using these phrases, you can say things like "in the morning," "in the afternoon," "in the evening," or "at night" to provide more context about the time of day.

Step 5: Combining "O'clock" with Parts of the Day

To give a complete and clear indication of the time, you can combine the use of "o'clock" with parts of the day. For example:

  • 6:00 AM - Six o'clock in the morning
  • 1:00 PM - One o'clock in the afternoon
  • 7:00 PM - Seven o'clock in the evening
  • 10:00 PM - Ten o'clock at night

This method ensures that the listener or reader understands not only the exact hour but also the part of the day being referred to.

Step 6: Practice and Application

Practice telling the time using "o'clock" and parts of the day in various scenarios. For example, if you have a meeting at 3:00 PM, you can say, "The meeting is at three o'clock in the afternoon." This practice will help you become more comfortable and accurate in telling the time.
