How it works and help
Times come from your browser's own time-zone data, and nothing you type is sent anywhere. Places are from GeoNames, CC BY 4.0, read from this site's own files when you search.

A little help along the way

Follow these steps. Every option is explained underneath. Everything runs in your browser; nothing is sent anywhere.

  1. Say what you are doingSee the time in other places is the usual. Convert a time takes what you type; Find a meeting time lays everyone's day side by side.
  2. Add placesSearch for a city, a country's capital or an abbreviation such as EST. Your own time comes first.
  3. Read the answerEach clock says the time, the day, the gap from you, daylight or night, and when its clocks next change.
  4. Share itCopy a link that carries the places and time, or add a meeting to your calendar.

Questions people ask

Is GMT the same as London time?
Only in winter. London keeps BST, an hour ahead of GMT, in summer; type London for its time all year.
When are London and New York four hours apart?
For a few weeks a year, because the US and the UK change their clocks on different weekends in March and autumn.
Can I convert to other places too?
Yes. Add more places after to, separated by commas, such as 14:00 GMT to EST, Delhi and Tokyo.
