How to Show Multiple Time Zones on Windows 11 (and Get Past the 3-Clock Limit).

Method 1 — Windows' built-in "Additional clocks" (up to 3 zones)

This is the no-install answer, and for many people it's enough. Windows lets you add up to two extra clocks next to your local time.

1. Open Settings → Time & language → Date & time. (Shortcut: right-click the clock in the taskbar → Adjust date and time.)
2. Scroll to Related links and open Additional clocks.
3. Switch on Show this clock, pick a time zone, and type a display name ("Tokyo", "NY team"…).
4. Repeat for the second slot. There are only two — that's the limit.

Where they show up: in the tooltip when you hover the taskbar clock, and in the calendar flyout when you click it. They do not sit on your desktop and they aren't visible at a glance.

Method 2 — The Clock app's World clock (unlimited, but hidden)

Windows' Clock app (formerly Alarms & Clock) has a World clock tab where you can add as many cities as you like and see them side by side.

The catch is that it's an app you have to open. It's a lookup tool, not a display — the moment you switch back to your work, your cities are gone from view. Pinning it to a second monitor works, but it takes up a whole window to show a few numbers.

Method 3 — A desktop widget or edge dock (always visible)

If you work with people in three or more zones, the real fix is to put the clocks where your eyes already are. That means a widget that stays on the desktop or docks to the screen edge. The main options for Windows:

A few notes on choosing. Sharp World Clock is the most complete suite (23,000+ cities, a meeting planner, weather) and is priced accordingly — a good pick if you want all of that. Rainmeter is the tinkerer's route: unlimited flexibility, but you'll spend an evening on skins and config files. Time Precision sits at the other end of the spectrum: it does one thing — keep the clocks you care about visible and out of the way — and adds timezone-aware alarms, and it costs nothing. It has 233 cities rather than tens of thousands and no weather or meeting planner, so if you need those, look at Sharp.

Which method should you use?

The trap almost every guide skips: daylight saving time

Time zones aren't fixed distances. The gap between two cities changes twice a year, and not on the same day for every country. That's where missed calls come from.

Take New York and London. Normally they're five hours apart. But the US and the EU switch clocks on different dates, so for a few weeks each year the gap is four hours. In 2026 it happens again very soon: London falls back on Sunday, 25 October, while New York doesn't fall back until Sunday, 1 November. For that one week, a 3 pm meeting in New York is 7 pm in London, not 8 pm. (In spring the mismatch is longer: the US springs forward on 8 March 2026, the EU not until 29 March.)

Two rules keep you safe:

• Track cities, not UTC offsets. A clock set to "UTC−5" is wrong half the year for New York. A clock set to "New York" follows the real timezone database (IANA) and shifts on the right date automatically. Any tool that asks you for a city rather than an offset does this.
• Watch the odd ones. Not everywhere observes DST, and some places don't share a neighbour's offset — Bali (UTC+8) and Jakarta (UTC+7) are an hour apart despite being in the same country. A good clock is validated against IANA rather than guessing.

How to set an alarm in another time zone

This is the second gap. The taskbar's Additional clocks don't have alarms at all, and, at the time of writing, the alarm editor in Windows' Clock app has no time-zone field: an alarm fires at a time on your PC's clock. If you need something to ring at 07:30 in Tokyo — a stand-up, a market open, a livestream — you have to convert it in your head and hope daylight saving didn't move it.

The workarounds, from worst to best:

1. Convert by hand and set a normal alarm. Works until the week the two countries change clocks on different days (see above) — then it silently rings an hour early or late.
2. Use a calendar event with a notification in the other zone's time. Reliable, but it lives in your calendar, not on your desktop, and doesn't take over the screen when you're in a meeting.
3. Use an app with timezone-aware alarms. You set 07:30 on Tokyo's clock and the app does the conversion — including DST — every time. Sharp World Clock offers this, and so does Time Precision (click a city, set the alarm on that city's own clock; if a spring-forward skips your time, it rings an hour later rather than being lost; a "force popup" appears centered above everything until you dismiss it).

Setup tips for a multi-clock desktop

• Name clocks by person or team, not just city — "Maria (Lisbon)" is faster to parse than "Lisbon".
• Order by your day, not alphabetically: put the zone you check most, or the furthest-ahead zone, at the top.
• Choose 24-hour time if you work across zones — it removes the am/pm ambiguity when you're translating between them.
• Keep them on the screen edge, not over your work. A thin dock beats a floating window that keeps needing to be moved.
• Review after every DST change (late March/early April and late October/early November) that the offsets you expect still hold.
