How the time difference calculator works

The difference is each city's offset from UTC on the date you pick, subtracted. Offsets come from the IANA time zone database in your browser.

Because countries change their clocks on different dates — or not at all — the gap between two cities can change for a few weeks a year. The calculator lists every change in the year.

Examples

London is 5 hours ahead of New York for most of the year, but only 4 hours ahead for about three weeks in March and one week in late October.
Dubai doesn't change its clocks, so its gap to London is 4 hours in winter and 3 hours in summer.
