Common Mistakes When Converting Military Time

  • Forgetting the leading zero: 1:00 AM is 0100, not 100.
  • Using 24:00: Midnight is 00:00, not 24:00 (though some use 24:00 for end of day).
  • Misconverting 12:00 PM: 12:00 PM is 12:00, not 00:00.
  • Adding 12 to 12:00 AM: 12:00 AM becomes 00:00 (subtract 12).
