Plan a time

Times are computed in this browser. Nothing is sent anywhere.

Clocks use the IANA timezone database built into your browser, so the offset shown today reflects current rules — including daylight saving. Rare zones not in your browser's data fall back to UTC.

How to use

  1. Tick the zones to watch.
  2. Read the live clocks.
  3. Enter a date, time, and zone to see it everywhere.

What it supports

Up to 12 zones from a curated IANA list, saved in this browser. Offsets follow current DST rules; zones missing from a browser's data fall back to UTC.
