Military to standard:
Enter a military time such as 1430 to convert it into 2:30 PM.

A military time calculator is useful for work schedules, timesheets, travel, transportation, medical appointments, event planning, shift work, emergency services, and converting 12-hour time into 24-hour time.
It helps avoid AM/PM confusion by using one continuous 24-hour clock.
Your result shows the converted military or standard time. In duration mode, it also shows elapsed time, total minutes, decimal hours, start time, end time, and whether the time span crosses midnight.
