# Military Time Converter

Convert between 12-hour AM/PM and 24-hour military time. Full conversion table, spoken format, and guide to which countries use 24-hour time. Free, no ads.

## Quick answer

Add 12 to any PM time after noon: 3:00 PM = 1500. For AM: keep the same number, pad to 4 digits: 9:30 AM = 0930. Midnight = 0000, Noon = 1200.

## Frequently Asked Questions

The terms AM (ante meridiem, before midday) and PM (post meridiem, after midday) are technically ambiguous at 12:00 because noon is neither before nor after itself. Convention assigns 12:00 PM to noon and 12:00 AM to midnight, though many style guides recommend saying "12 noon" and "12 midnight" to avoid confusion.
Zulu time is the military/aviation designation for UTC (Coordinated Universal Time). The NATO phonetic alphabet uses Z (Zulu) for UTC, while other letters designate offset zones: A (Alpha) = UTC+1, B (Bravo) = UTC+2, etc. All flight plans, air traffic control, and meteorological reports use Zulu time to avoid time zone confusion.
