How to Change the Taskbar Clock Format in Windows

Tap a step to see how to change the taskbar clock format.

  1. Open Date & Time settings

    Go to Settings > Time & Language > Date & Time.

  2. Find format options

    Under "Formats," click "Change date, time, or number formats."

  3. Choose 12-hour or 24-hour time

    In "Additional settings for date, time, and region," you can switch the time format to the style you prefer.

  4. Turn on seconds display (optional)

    Through a registry edit or certain settings, you can make the taskbar clock also show seconds.

  5. Why it helps

    Depending on your work habits or personal preference, choosing 12-hour (AM/PM) or 24-hour format makes it easier to read the time at a glance.

Switch to a Time Display That Feels Familiar

If 24-hour format feels unfamiliar, or you find an AM/PM split easier to read, a quick settings change lets you switch to whichever format suits you.

Check That Your Computer's Clock Stays in Sync

It's also worth confirming your system clock updates automatically, since a drifting clock can cause scheduling or login issues with some apps and networks. Most operating systems can sync time automatically over the internet β€” check your date and time settings if the clock ever looks off.

Frequently Asked Questions

Can I also change how the date is displayed?

Yes. On the same settings screen you can change the date order too, such as year-month-day or month-day-year.

Does turning on seconds use more battery?

Showing seconds refreshes the display more often, which can use a tiny bit more power, but the effect is negligible for everyday use.
