FAQ

How many cities can I add?

You can add all 36+ available cities from the search dropdown. There is no hard limit on how many clocks you can display.

Is the time accurate?

The clock uses your device's system time combined with the browser's Intl.DateTimeFormat API for timezone conversion. It's as accurate as your system clock.

What does the sun/moon icon mean?

โ˜€๏ธ (sun) means it's between 6:00 AM and 5:59 PM local time in that city. ๐ŸŒ™ (moon) means it's nighttime (6:00 PM to 5:59 AM).

Will my city list be saved?

Yes. Your selected cities are saved in your browser's localStorage. They will persist across page reloads and browser sessions until you clear your browser data.

Does this work offline?

Yes. Since all timezone calculations are done by the browser's built-in APIs, no internet connection is needed after the page loads.
