How to Convert 0400 to Standard Time

0400 converts to 4:00 AM in 3 steps:

  1. 0400 falls between 0100 and 1159, so drop the leading zero: 400.
  2. Insert a colon before the last two digits: 4:00.
  3. Add AM, because hours 01 to 11 are morning: 4:00 AM.

To go the other way, 4:00 AM becomes 0400: add a leading zero to 4, then remove the colon.
