answered 19 May 2026What is AM and PM?
A.VERIFIED ANSWERfact-checked by tutors
- AM = Ante Meridiem (Latin: "before midday") covers 12:00 midnight to 11:59 morning
- PM = Post Meridiem (Latin: "after midday") covers 12:00 noon to 11:59 night
Quick reference:
| Time | AM or PM | Period |
|---|---|---|
| 12:00 | AM | Midnight |
| 7:00 | AM | Morning |
| 12:00 | PM | Noon |
| 7:20 | PM | Evening |
| 11:59 | PM | Night |
Confusing facts:
- Morning 7 o'clock = 7 AM
- Afternoon starts at 12 PM (noon), NOT 12 AM
- 12 AM = Midnight | 12 PM = Noon — the most commonly confused pair
- 7:20 PM = evening or night, not morning
