How to use this calculator

Enter the requested values and units.

Review the assumptions and any warnings shown with the result.

Use the result together with the cited source and your real-world requirements.

Formula

For 12-hour input, compute hour24 = (hour modulo 12) + (isPm ? 12 : 0). For military input, parse a four-digit time from 0000 through 2359, compute hour12 = hour24 modulo 12, display 0 as 12, and use AM before 1200 or PM from 1200 onward.

Worked example

Worked example: Inputs: Hour (1–12): 1; Minute: 30; AM or PM: PM. Outputs: 12-hour clock time: 1:30 PM; 24-hour time: 13:30; Compact military time: 1330. Related examples: “1500 military time” is another input pattern; enter its values instead of reusing this worked example.

Assumptions and limits

  • The result depends on the values, units, and assumptions entered. It does not infer missing context.
