How to Read and Show Quarter Hours on a Clock
In this chapter you will learn to tell time quarter past and quarter to and time to half hour. Constructing on this, tell time quarter hour problem in maths focuses on telling time to quarter hour, using both digital and analog formats. The time quarter past and quarter to math problems consists of interactive problems on reading time on a clock, setting time on an analog clock, and exposes students to different ways of saying the same time. For example, 3:45 and quarter to 4 are different ways of saying the same time.

Time Quarter Past, Quarter to and Half Hour
Let’s get to know the various ways to tell time to quarter hours
In 5 minute augmentations, when it's past the hour (up to 30 minutes past) we say "past".
When it's before the hour (after 30 minutes past) we state "to".
There are 60 minutes in an hour.
30 minutes is half an hour (exactly half of an hour/half of 60 minutes), we say "thirty" or "half past".
Fifteen minutes is quarter of an hour, we say "quarter past" or "quarter to" or "fifteen" or "forty-five".
09:00- it’s nine o'clock in the morning.
15:00- it’s three o'clock in the afternoon.
15 minutes past the hour is said to be quarter past:
06:15- it’s quarter past seven in the morning (6:15 is 6:15 AM in the morning)
13:15- It's quarter past two in the afternoon. (13:15 is 1:15PM in the afternoon)
Time Measurement to Tell Time to Quarter Hours
Time measurement for 15 minutes, 30 minutes, and 45 minutes can be depicted in the following manner. They are:
Quarter to - This implies that there are 15 minutes remaining to complete a given hour. For example, 06:45 means there are 15 minutes still remaining to reach 7:00. This is also read as "quarter to seven".
Quarter Past - This implies that 15 minutes have passed after the hour has begun. For example, 09:15 means 15 minutes have passed after 9:00. This is read as "quarter past nine".
Half-Past - This implies that 30 minutes have passed after the hour has begun. For example, 06:30 means 30 minutes have passed after 6:00. This is also read as "half-past six".
Solved Examples
Let’s practice some quarter hour problem in maths that you will find in your tell time quarter past and quarter to worksheets.
Example:
Calculate the measurement of time between 1:00 to 5:00.
Solution:
The distance between two vertical lines depicts 1 hour. Thus, there are 4 hours between 1:00 and 5:00.
Therefore, the time between 1:00 and 4:00 is 4 hours.
Example:
Alex's and Amaira anniversary falls on June 9. Their friend's anniversary falls on September 17. Find out the number of weeks and days between the two dates.
Solution:
The month of June consists of 30 days. The number of days after Alex's and Amaira anniversary (June 9) is 30 - 9 = 21.
The Months of July and August have 31 days each. Beginning from 1st to 17th, we have 17 days in the month of September. So, there are (21 +31+31+17) days which equals 100 days.
In order to find the number of weeks, divide the number of days by 7 and express the outcome as a mixed fraction. 100/7 is 14 2/7 weeks.
∴ There are 102 days between Alex's-Amaira’s and their friend's anniversary.
Usability to Tell Time to Quarter Hours

The worksheets involve:
Converting clock times into digital time.
Reading and calling out the time using the language 'past' and 'to'.
Learning the quarter past and quarter to times.
Practice o'clock, quarter past, quarter to and half past.
Convert times into digital format.
FAQs on Tell and Set Time to Quarter Hours Made Simple
1. What does it mean to tell time to the quarter hour?
Telling time to the quarter hour means dividing the hour into four equal parts, just like cutting a pizza into four slices. Each part is 15 minutes. We use special phrases like 'quarter past', 'half past', and 'quarter to' to describe these times.
2. How many minutes are in a 'quarter past' and 'quarter to' an hour?
Understanding the minutes helps in reading the clock correctly.
- A 'quarter past' the hour means 15 minutes have passed. For example, 'quarter past 8' is 8:15.
- A 'quarter to' the next hour means there are 15 minutes left until that hour starts. For example, 'quarter to 8' is 7:45.
3. How do you set the clock hands for 'quarter past 10'?
To show 'quarter past 10' on an analog clock, you need to place the hands correctly:
1. The minute hand (the long hand) must point directly at the number 3, which represents 15 minutes past the hour.
2. The hour hand (the short hand) should be placed slightly past the number 10, showing that some time has passed since 10 o'clock.
4. Why is 15 minutes called a 'quarter hour'?
It's called a 'quarter hour' because a full hour has 60 minutes. If you divide these 60 minutes into four equal parts (a 'quarter' means one-fourth), you get 15 minutes in each part (60 ÷ 4 = 15). So, 15 minutes is exactly one-quarter of a full hour.
5. What is the main difference between the clock hands at 3:15 (quarter past 3) and 3:45 (quarter to 4)?
The main difference is the position of both the minute and hour hands.
- At 3:15 (quarter past 3), the minute hand points to the 3, and the hour hand is just a little past the 3.
- At 3:45 (quarter to 4), the minute hand points to the 9, and the hour hand has moved much closer to the 4, showing it's almost 4 o'clock.
6. When the time is 'quarter to 5', where should the hour hand be pointing?
This is a tricky but important detail! When the time is 'quarter to 5' (which is 4:45), the hour hand should not be pointing directly at the 4. It should be very close to the 5, because the hour is almost over and it is getting ready to be 5 o'clock.
7. Can you give some examples of using quarter hours in daily life?
Yes, we use these phrases all the time! For instance:
- Your school might have a lunch break that starts at 'quarter past 12' (12:15).
- You might tell a friend, "Let's meet at the park at 'quarter to 5'" (4:45).
- Your favourite TV show might end at 'half past 6' (6:30).
