Overview

Convert a time between 12-hour format (like 2:30 PM) and 24-hour format (like 14:30), in either direction. This is a pure format conversion - it doesn't touch timezones or dates, just the way a single clock time is written. Useful for converting a time from a schedule, itinerary, or system that uses one format into the other. Runs entirely client-side.

How to use this tool

  3. Read the result instantly. The converted time updates live as you type.

Frequently asked questions

No - this only converts the format a single clock time is written in (12-hour AM/PM vs 24-hour), not the timezone it's in. For converting a time across timezones, use the Timezone Converter instead.

12:00 AM (midnight) converts to 00:00 in 24-hour format, and 12:00 PM (noon) converts to 12:00 - the one part of the conversion that trips people up by hand, handled correctly here.
