How to use it

  1. In Time zones, set a date and time and the zone it is in. Your list of cities shows the same moment everywhere. Add or remove cities as you like.
  2. In Unix timestamp, paste a timestamp to read it as a date, or pick a date to get its timestamp. The current one ticks along at the top.
  3. In Date difference, pick two dates to get the days, weeks, months and business days between them, or add days, weeks or months to a date.

What it’s for

Setting up a call with people in other countries, checking a deadline in someone else’s time zone, reading timestamps in logs and databases, and counting the days to a trip or the working days left in a project. Daylight saving changes are handled for every date, and your city list is remembered in your browser.
