Conversion charts
Hour-by-hour charts for popular pairs, recalculated every day so clock changes are never missed. Gaps shown for Wednesday, September 30, 2026.
How the conversion works
Your time and date are turned into one exact moment using the official rules for the zone you start from (the IANA time zone database, the same data phones and computers use). That moment is then read on the other zone's clock, so each zone's daylight saving time is applied for that specific date — not today's offset.
On the nights clocks change, some times are skipped and others happen twice. The converter tells you when that affects your time and which one it used.

Frequently asked questions
Does the converter handle daylight saving time?
Yes. It converts the exact moment on the date you pick, using each zone's own rules, so a meeting in March or November gets the offsets that apply then. If the time you enter is skipped or repeated because the clocks change that night, the result says so.
What's the difference between GMT and UTC?
For everyday use they show the same time. UTC is the worldwide reference time and never changes; GMT is also the winter time zone of the UK. London switches to British Summer Time (one hour ahead of UTC) from late March to late October, while UTC stays put.
Why is the gap between two zones different at some times of year?
Countries change their clocks on different dates, and many — India, Japan and most of Africa among them — don't change them at all. The US moves its clocks in the second week of March and the UK two to three weeks later, so for a short while New York is only 4 hours behind London instead of 5.

Clocks change on different weekends in the US and Europe, which shifts the gap between them for a few weeks each year. Read daylight saving time 2026–2027: when the clocks change.
