Military time converter

How this calculator works

A Military Time Converter rewrites clock values between twelve-hour wording and four-digit twenty-four-hour form. HourPunch accepts common inputs such as 9:30 AM, 0930, or 17:45, depending on direction, and shows both standard and military strings when the entry is valid. Conversions run locally without an account. This page changes notation; it does not calculate hours worked or pay.

Standard times without AM or PM are rejected in standard-to-military mode to avoid noon and midnight mix-ups. Military entries use hours zero through twenty-three and minutes zero through fifty-nine. Midnight is 0000 in military form and 12:00 AM in standard form. Noon stays hour twelve as 1200 and 12:00 PM.

Converting format does not change elapsed time between two events—after you translate punches, use the time between calculator for duration. Use the chart above for exact military strings before you enter punches on a time card.

Worked example

Converting 9:30 AM to military time yields 0930. Five forty-five PM becomes 1745 because seventeen hours and forty-five minutes sit on a twenty-four-hour dial. Reading 1745 back gives 5:45 PM. Twelve AM stays 0000; twelve PM stays 1200. Colon-style 17:45 can parse as twenty-four-hour input when converting toward standard wording.

Seconds, time zones, and locale spacing are not included. Use converted strings to read rosters or punch printouts, then enter matching times on the time clock or time between tools for hour totals.

Totals shown here are estimates for checking a pay stub or time sheet. They are not official payroll, tax, or legal advice.
