How to Add Two Extra Clocks on Windows 10

Windows 10 lets you add up to two additional time-zone clocks alongside the PC’s main clock. Open Control Panel, go to Clock and Region > Add clocks for different time zones, enable one or both clock slots, and choose a time zone and display name for each. Then click the taskbar clock to view them. These extra clocks are for checking other locations; they do not change the time zone Windows uses for the PC.

Add two extra clocks in Windows 10

1. Open Control Panel. Select Start, type Control Panel, and open the desktop app.
2. Open the clock settings. In Category view, select Clock and Region, then choose Add clocks for different time zones. If Control Panel uses Large or Small icons, open Date and Time instead, then select the Additional Clocks tab.

3. Set the first additional clock. On the Additional Clocks tab, check Show this clock in the first section. Open its time-zone menu and select the region you want. In Clock name, enter a short label, such as “London” or “Work.”
4. Add another time zone if needed. Check Show this clock in the second section, choose its time zone, and give it a distinct name. Windows supports two additional clocks here, for three clocks total when you include the PC’s primary clock.

5. Save and check the result. Select Apply, then OK. On the taskbar, click the date and time in the notification area. The calendar flyout shows the primary clock and the additional clocks with the names you entered. Depending on the selected region, an extra clock can show a different calendar date as well as a different time.

If the Additional Clocks tab is hard to find

The route can look different depending on Control Panel’s view. In Category view, use Clock and Region. In icon view, open Date and Time directly. You can also press Windows key + R, enter control timedate.cpl, and press Enter to open the Date and Time dialog; then look for Additional Clocks.

If the extra clocks do not appear in the taskbar flyout, reopen the tab and confirm that each desired Show this clock box is checked. Select Apply before closing the dialog, then click the taskbar clock to view the flyout. If the taskbar clock itself is hidden, check the time-and-date display setting in Windows.

What additional clocks do—and what they do not do

Additional Clocks provide quick reference times. They do not create separate system clocks, change your PC’s primary time zone, or alter how Windows timestamps files and scheduled events. If the main clock is wrong, check Settings > Time & language > Date & time and review the PC’s time and time-zone settings. Microsoft explains those controls in its Windows date, time, and time-zone guide.

Choose the time-zone entry for the location you need, rather than treating the displayed UTC offset as a permanent difference. Regions that observe daylight saving time can change their offset during the year, and locations may not switch on the same dates. Windows calculates the clock from the selected time-zone rules. If a location’s time looks unexpected, verify that you picked the intended region and that Windows has current time-zone information.

Need more than two extra locations?

Windows’ taskbar feature is limited to two additional clocks. For a longer list, use the World clock section in the Clock app: open Start, search for Clock, choose World clock, and add cities. Microsoft also documents how to compare times in that view. Those locations stay inside the Clock app; they are not added to the taskbar calendar flyout. See Microsoft’s World clock instructions.

Windows 10 support note: Microsoft ended standard support for Windows 10 on October 14, 2025. The clock settings described here remain local Windows features, but Microsoft no longer provides free Windows Update software updates, technical assistance, or security fixes for Windows 10 after that date.
