Time misconceptions

Fix confusion around quarter to, 24-hour notation and crossing noon or midnight.

Quick answer

Time misconceptions happen when we get confused about how time works, especially with quarter to, quarter past, and 24-hour clocks. The key is to understand that time is like a circle that goes around and around, and we need to be clear about what each part means.

Learning outcome

By the end of this page, you will understand how to read time correctly on both 12-hour and 24-hour clocks, and you'll know how to tell the difference between quarter to, quarter past, and other time phrases. Success signs:
  • You can tell the time to the nearest 5 minutes on both clocks
  • You can say what "quarter to" and "quarter past" mean
  • You can read a 24-hour clock and understand when it changes from morning to night
  • You can solve time problems using real-life examples

Why this matters

Time helps us know when to wake up, go to school, eat lunch, play, and go to bed. Understanding time helps us plan our day, be on time for events, and know how long things take. When we get confused about time, we might miss our bus, be late for a party, or not understand what time it is in a different country. Learning to read time correctly helps us be more confident and responsible.

How it works

Time is like a circle that goes around and around. A clock face has 12 hours marked from 1 to 12. When the hour hand moves from 12 to 1, it's one hour. The minute hand moves around the clock to show how many minutes have passed. We can think of time in two ways:
  • 12-hour clock: Shows morning (AM) and night (PM) times
  • 24-hour clock: Shows all 24 hours of the day without AM or PM
When we say "quarter to" or "quarter past", we're talking about how far the minute hand has moved from the hour:
  • Quarter to means 15 minutes before the hour
  • Quarter past means 15 minutes after the hour

Examples you can see

Let's look at some examples that help you understand time better. Example 1: Quarter to and quarter past
  • Quarter to 3 means 15 minutes before 3 o'clock. That's 2:45.
  • Quarter past 3 means 15 minutes after 3 o'clock. That's 3:15.
Example 2: 12-hour vs 24-hour clocks
Time 12-hour clock 24-hour clock
3:00 in the afternoon 3:00 PM 15:00
11:00 at night 11:00 PM 23:00
12:00 midnight 12:00 AM 00:00
12:00 noon 12:00 PM 12:00
Example 3: Real-life time
  • Your school starts at 9:00 AM. That's 9:00 in the morning.
  • Your maths lesson ends at 10:15 AM. That's 15 minutes after 10 o'clock.
  • Your bedtime is at 8:00 PM. That's 8:00 in the evening.

Try it as a mini adventure

The Time Adventure Challenge You are a time detective who needs to solve a mystery! Your job is to find out what time the following events happen in a day.
  1. First time: The sun rises at quarter past 6 in the morning. What time is that?
  2. Second time: Your lunch break starts at quarter to 12. What time is that?
  3. Third time: The movie starts at 2:30 PM. What time is that in 24-hour format?
  4. Fourth time: You wake up at 7:00 AM and go to bed at 9:00 PM. How many hours did you sleep?
  5. Fifth time: Your friend's birthday party starts at 10:45 PM. What time is that in 24-hour format?

Common mistakes

  • Mistake: Thinking that "quarter to" means 15 minutes after the hour. Why it happens: Confusing "past" and "to" in time words. Fix: Remember that "quarter to" means 15 minutes before the hour, not after.
  • Mistake: Mixing up 12-hour and 24-hour clocks. Why it happens: Not understanding that 24-hour clocks go from 00:00 to 23:59. Fix: Practice converting between the two formats. 12:00 PM is 12:00, and 12:00 AM is 00:00.
  • Mistake: Forgetting that time goes from morning to night at 12:00. Why it happens: Not understanding that noon and midnight are special times. Fix: Remember that 12:00 PM is noon and 12:00 AM is midnight.
  • Mistake: Thinking that 24-hour clocks are harder than 12-hour clocks. Why it happens: Not knowing that 24-hour clocks just keep going after 12. Fix: Practice counting from 0 to 24, and remember that 13:00 is 1:00 PM.

Parent and carer guide

As a parent or carer, you can help your child understand time by:
  • Using a real clock at home and pointing out the hour and minute hands
  • Practising telling time together every day
  • Playing time games like "What time is it?" or "Guess the time"
  • Using real-life examples like "We eat lunch at 12:00, and dinner is at 6:00"
  • Practising converting between 12-hour and 24-hour clocks
  • Letting your child help plan their day using a clock
Remember to be patient! Time can be tricky, and it's okay if your child makes mistakes. Encourage them to keep trying and ask questions.

FAQ

What is the difference between a 12-hour and a 24-hour clock?

A 12-hour clock shows the time from 1 to 12 twice, once for morning (AM) and once for night (PM). A 24-hour clock shows all 24 hours of the day from 00:00 to 23:59 without AM or PM.

Why do we use 24-hour clocks?

24-hour clocks are used in many places, especially in military, aviation, and public transport, because they are clear and don't confuse morning and evening times.
