Convert between 12-hour & 24- hour clock Worksheets - Free Printable

Let's solve each clock shown in the worksheet and write the time in both 12-hour and 24-hour formats.

---

Understanding the Clocks:

- The hour hand (shorter) tells the hour.
- The minute hand (longer) tells the minutes.
- Each number on the clock represents 5 minutes (e.g., between 1 and 2 is 5 minutes).
- There are 60 minutes in an hour, so each small tick = 1 minute.
- In 12-hour format, we use AM/PM (AM = morning, PM = afternoon/evening).
- In 24-hour format, we go from 00:00 to 23:59:
- 1:00 AM → 01:00
- 1:00 PM → 13:00
- 12:00 PM → 12:00
- 12:00 AM → 00:00

Now let's analyze each clock:

---

a. Already Solved

Clock shows:
- Hour hand between 3 and 4 → 3 o'clock
- Minute hand at 1 → 5 minutes past
→ 3:05

In 12-hour format: 3:05
In 24-hour format: 15:05 ✔ (since 3 PM = 15:00)

---

b.

- Hour hand between 7 and 8 → 7 o'clock
- Minute hand at 5 → 25 minutes past (each number = 5 min; 5 × 5 = 25)
→ 7:25

Now, is it AM or PM? Since no context is given, we consider both possibilities.

But for 12-hour format, we write:
- 7:25 AM or 7:25 PM

For 24-hour format:
- 7:25 AM → 07:25
- 7:25 PM → 19:25

So possible times:
- 12-hour: 7:25 AM or 7:25 PM
- 24-hour: 07:25 or 19:25

But since the question says “write all possible times”, we include both.

✔ So answer:
- 12-hour clock: 7:25 AM / 7:25 PM
- 24-hour clock: 07:25 / 19:25

---

c.

- Hour hand between 6 and 7 → 6 o'clock
- Minute hand at 10 → 50 minutes past (10 × 5 = 50)
→ 6:50

Again, could be AM or PM.

So:
- 12-hour: 6:50 AM or 6:50 PM
- 24-hour: 06:50 or 18:50

✔ Answer:
- 12-hour clock: 6:50 AM / 6:50 PM
- 24-hour clock: 06:50 / 18:50

---

d.

- Hour hand between 1 and 2 → 1 o'clock
- Minute hand at 3 → 15 minutes past (3 × 5 = 15)
→ 1:15

Could be AM or PM.

So:
- 12-hour: 1:15 AM or 1:15 PM
- 24-hour: 01:15 or 13:15

✔ Answer:
- 12-hour clock: 1:15 AM / 1:15 PM
- 24-hour clock: 01:15 / 13:15

---

e.

- Hour hand between 11 and 12 → 11 o'clock
- Minute hand at 5 → 25 minutes past (5 × 5 = 25)
→ 11:25

Could be AM or PM.

So:
- 12-hour: 11:25 AM or 11:25 PM
- 24-hour: 11:25 or 23:25

✔ Answer:
- 12-hour clock: 11:25 AM / 11:25 PM
- 24-hour clock: 11:25 / 23:25

---

✔ Final Answers:

| Letter | 12-Hour Clock | 24-Hour Clock |
|--------|----------------------|--------------------|
| a. | 3:05 | 15:05 |
| b. | 7:25 AM / 7:25 PM | 07:25 / 19:25 |
| c. | 6:50 AM / 6:50 PM | 06:50 / 18:50 |
| d. | 1:15 AM / 1:15 PM | 01:15 / 13:15 |
| e. | 11:25 AM / 11:25 PM | 11:25 / 23:25 |

🔍 Explanation Summary:

- Always read the minute hand first (each number = 5 mins).
- Then read the hour hand — if it’s between two numbers, take the lower one.
- For 12-hour format, add AM or PM based on time of day.
- For 24-hour format:
- AM: same as 12-hour (except 12 AM = 00:00)
- PM: Add 12 to the hour (e.g., 1 PM = 13:00, 12 PM = 12:00, 11 PM = 23:00)

Since the problem asks for all possible times, we assume both AM and PM are valid unless specified otherwise.
