How to use
- On the left, type a time (like 2:30) and pick AM or PM — the military time appears on the right instantly.
- On the right, type military time (like 1430 or 14:30) — the 12-hour time appears on the left instantly.
- Changing either side updates the other automatically.
- Red text under a box means the input is invalid — check the format and try again.
Tips
- The tricky cases: 12:00 AM is 00:00 (midnight) and 12:00 PM is 12:00 (noon) — not the other way round.
- Military time is always 4 digits with no AM or PM, so 7:00 PM becomes 1900.
- Minutes work the same on both sides: 6:45 PM = 1845, and 0605 = 6:05 AM.
