Offsets and daylight-saving dates are computed from the IANA Time Zone Database through the JavaScript Intl API — the same rules your phone and computer use. The year table above was generated from those rules when this page was built; the live converter uses the rules installed in your own browser, so it stays correct if a country changes its clocks.
