World Clock

Coordinating across time zones for calls, broadcasts, or travel means constantly doing mental math. This tool keeps a live, ticking clock for every city you add.

Why use this tool?

Coordinating across time zones for calls, broadcasts, or travel means constantly doing mental math. This tool keeps a live, ticking clock for every city you add.

How it works

  1. Pick a city from the dropdown and click Add.
  2. Its clock starts ticking immediately, alongside your others.
  3. Each card shows the time difference from your own, so you don't have to calculate it.

Frequently asked questions

Does it account for daylight saving time?Yes — it uses your browser's built-in time zone database, which automatically adjusts for daylight saving in each region.
Can I save my list of cities?Yes, your selected cities are remembered the next time you visit.
Can I convert a specific future time, not just live clocks?Not yet — this version shows live time only. It's a feature we're considering for a future update.

Want to convert a specific future time across zones, not just live clocks?
