New to Greenwich Mean Time? Read here: GMT
☀ On 25th March Europe clocks go forward one hour, Daylight Saving Time (DST) starts.
☀ USA and Canada have already moved to Daylight Savings.
Pay particular attention when converting time involving USA and Europe during the short interval between USA summer time and Europe summer time.
Our conversion tools will always work correctly at any time of the year.
Quite a lot of countries in both hemispheres do not observe DST at all.
If you are not sure when clocks change in your place or places of interest, we recommend using the new Time Converter . If you already know the respective time zone GMT offsets, the old converter is still available.

GMT offsets and Time Zones come together for you in the CONVERSION TO pages.
Imagine travelling to a different country, in a different part of the world, and waking up much earlier or later, due to the time zone difference.
On holiday it would be useful to know what time the sun rises and sets, even before our biological clock finally adjusts. Bookmark the Sunrise gadget below and use it in conjunction with the Moon one.
If only your ideas travel, as it happens in today's international business, the Meeting Planner will come in handy.
While the Sun and the Earth approach the bi-annual solstice moment, the Moon is continuing its monthly cycle.
