Methodology and limits
12-hour to 24-hour: 12 AM becomes hour 00; other AM hours keep their hour. 12 PM stays hour 12; 1–11 PM add 12. Minutes are unchanged and padded to two digits.
24-hour to 12-hour: hour 00 becomes 12 AM; 01–11 are AM; 12 is PM; and 13–23 subtract 12 and use PM.
This tool changes notation only. It does not change the date or time zone, and it does not assert that one written or spoken format is required by every military unit, agency, hospital, or profession.
