12-hour & 24-hour time converter
Translate explicitly written AM/PM times and 24-hour clock times.
A clear answer. Here’s how.
12-hour input requires hours 1–12 and AM/PM; 12 AM is midnight and 12 PM is noon. 24-hour input uses hours 00–23. Minutes are required and seconds optional; each must be 00–59. Reports both clock formats without applying a date, location or time zone.
