Want more useful things on your clock popup? Add your calendar! You can synchronize Windows 10 with online calendars like Google Calendar, Apple’s iCloud Calendar, and Exchange calendars. You’ll see the times in your other two selected time zones right below the local time zone.
You can also click the clock on the taskbar and look at the top of the panel. You’ll see the time in those other time zones. To see your other time zone clocks without clicking anything, you can hover your mouse cursor over the clock on the taskbar. You can include the DoW name in it (by specifying ddd modifier), so in taskbar you will have 'Thu, ' as date and don't need 3rd row just for the day of week. You can add up to two additional time zones here that’s it. Windows 10 shows the date in taskbar using the Short Date format.
