How to Convert 0042

0042 sits in the first hour after midnight. The rule for 0000–0059: the standard hour is 12, and the label is AM.

00 = 12 → 12:42 AM AM — the first hour after midnight counts as 12 AM (the minutes, 42, stay exactly the same).

Going the other way: 12:42 AM counts as hour 00 — the hour after midnight — so it becomes 0042. Or skip the math — type 0042 into the military time converter and convert any time instantly on the home page.

When You'll See 0042

0042 sits in the first minutes of a new day. Overnight hospital shifts often run 1900–0700, so 0042 (12:42 AM) lands mid-shift — vital-sign rounds, medication passes, and dispatch logs all carry this timestamp. You'll also see 0042 on red-eye flight schedules and 24-hour security reports.

To say it out loud, read the two pairs: "zero forty-two." In formal military usage you may also hear "zero hundred forty-two hours."
