Tabla de Hora Militar y Reloj de 24 Horas

Military time is a concise 24-hour timekeeping system that eliminates the need for 'AM' and 'PM' designations. The day begins at 0000 (midnight) and progresses through 2359 (11:59 PM). Times are written as four continuous digits without colons in official US military and NATO operations.

Hours from 0100 to 0900 begin with 'Zero' followed by the number and 'Hundred' (e.g. 0700 is pronounced 'Zero Seven Hundred Hours'). For afternoon and evening hours, the full number is stated (e.g. 1500 is 'Fifteen Hundred Hours', and 2130 is 'Twenty-One Thirty Hours').

In military and aviation operations, 'Zulu Time' (often denoted by the letter 'Z') refers to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT). Because military forces deploy globally across diverse time zones, Zulu time provides a universal, standardized reference point that prevents scheduling errors.

Hospitals, first responders, and aviation flight controllers rely on military time to eliminate life-critical ambiguities between morning and evening (e.g. mistaking 8:00 AM medication administration for 8:00 PM). It creates immutable clarity in patient charting, triage, and mission logs.
