How the math works

  1. AM hours1:00 AM to 11:59 AM keep their hour, with a leading zero: 7:05 AM = 0705.
  2. The midnight hour12:00 AM to 12:59 AM become 00: 12:30 AM = 0030.This is the case most charts get wrong: 12:30 AM is half an hour after midnight, not after noon.
  3. Noon12:00 PM to 12:59 PM stay 12: noon = 1200.
  4. PM hours1:00 PM to 11:59 PM add 12 to the hour: 7:15 PM = 19 + 15 → 1915.
  5. 24002400 = the end of the day = 0000 of the next day.A shift that ends at 2400 ends at midnight; the hours calculator counts it the same as an end time of 12:00 AM.

What this doesn’t cover

  • Time zones and Zulu (UTC) time: the converter changes how a local time is written; it does not move it to another zone.
  • Seconds: time cards record minutes; seconds are not modeled.

Military time chart

Every hour of the day. The minutes carry straight across: 7:15 PM is 1915, 12:30 AM is 0030.

Midnight

12:00 AM = 0000

The start of the day. The first hour is 00: 12:30 AM is 0030.

Noon

12:00 PM = 1200

After noon keep counting: 1:00 PM is 1300.

2400

2400 = end of the day

The same instant as 0000 the next day. Some schedules end a shift at 2400 so it stays on the same date.
