To protect OLED and AMOLED displays, the clock subtly shifts its position every 10 minutes in a slow circular
pattern. Dark Mode further reduces the risk of burn-in. Protection does not apply in embedded mode. Use
?burnin=false to disable.
This site works as a Progressive Web App. You can install it on your phone or computer for a full-screen clock and offline use. Use your browser’s menu (e.g. “Add to Home Screen” or “Install app”) to install.
Add ?tz= to the URL with any IANA
timezone:
clocksimulator.com/?tz=America/New_York clocksimulator.com/?tz=Europe/London clocksimulator.com/?tz=Asia/Tokyo
Show multiple clocks at once by separating timezones with commas. This automatically enables
dashboardMode. Use &rows= to control the grid layout:
clocksimulator.com/?tz=UTC,Europe/Helsinki,America/New_York clocksimulator.com/?tz=UTC,Europe/Helsinki,America/New_York,Asia/Tokyo&rows=2 (dashboardMode)
You can also use the dashboard builder (ⓘ → Build dashboard) to visually add timezones and configure the grid.
Embed the clock on any website via an <iframe>. Use the built-in embed panel
(ⓘ → Embed this clock) to configure and copy the code.
