12 Hour Clock
See the current local time in a large AM/PM display with seconds, date, 24-hour comparison, copy, and fullscreen controls.
How this 12-hour clock works
This clock displays the current local time in 12-hour format, using AM and PM to distinguish morning from afternoon and evening. It uses your browser and device clock, so it is a practical display tool rather than an official time source.
Seconds are available when you need to watch the live rollover, and the date can stay visible for desk, classroom, or second-screen use.
12-hour time vs 24-hour time
The 12-hour format repeats 1 through 12 twice each day and adds AM or PM. The 24-hour format runs from 00 through 23 and does not need AM or PM labels.
For the opposite format as the main display, use the 24 hour clock. For compact military-style notation and conversion notes, try the military time clock or military time converter.
Common uses
A 12-hour AM/PM clock is useful for everyday local time, classroom displays, desk clocks, fullscreen second-screen clocks, and users who prefer AM/PM time. For a general clock page, open the digital clock. For local time context, use current local time.
