Calculate the time difference between any two countries
How it is calculated
We use the IANA time zone database (tzdata), which browsers and operating systems use as well. For every day the UTC offset of both main zones (London and Santiago (Chile)) is looked up; the difference only changes when one of the countries changes its clocks. In the UK and the EU that happens on the last Sunday of March and October at 01:00 UTC; in the US on the second Sunday of March and the first Sunday of November (15 U.S.C. § 260a).
Limits: countries can change their time rules at short notice; this page shows the time zone database as of the update date. For countries with several time zones the main zone is used; the others are listed in the time zone table.
