In short: Germany uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer. Clocks go forward from 2 to 3 a.m. on the last Sunday in March and back from 3 to 2 a.m. on the last Sunday in October. Because other countries change on other dates or not at all, the time difference shifts during the year.

Countries with their own daylight saving time change on other dates than the EU. In the weeks in between the difference is one hour off, e.g. for the USA in March (2nd to 4th Sunday) and from late October to early November. In the southern hemisphere, summer time runs from October to April.

Clock changes in Germany: dates until 2030

In the EU, summer time starts on the last Sunday in March and ends on the last Sunday in October, both at 01:00 UTC (Directive 2000/84/EC).

How the time zone converter works

Every local time is Coordinated Universal Time (UTC) plus the zone's UTC offset. The converter turns the time you enter into UTC and calculates every target zone from there:

ttarget=tstart−offsetstart+offsettargett_{\text{target}} = t_{\text{start}} - \text{offset}_{\text{start}} + \text{offset}_{\text{target}}
12:00−(+1)+(−5)=6:0012{:}00 - (+1) + (-5) = 6{:}00

Example: Berlin in winter (UTC+1) → New York (UTC−5)

The offset comes from the IANA time zone database built into your browser. It records for every region whether and when clocks change, including past rules, so the time difference is right for any date, not just today.

Times inside the spring-forward gap (e.g. 02:30 on the last Sunday in March) are moved forward by the length of the gap. Times that occur twice in October refer to the first one, i.e. summer time.

The meeting planner checks the first location's day in 15-minute steps: a slot works if it lies completely within local working hours at every location. The current time comes from your device; no data is stored.

Frequently asked questions

Usually 6 a.m.: New York is 6 hours behind Germany all year because both sides put their clocks forward in summer. The exception is a few weeks a year when the USA is already or still on summer time but Germany is not: from the 2nd Sunday in March to the last Sunday in March, and from the last Sunday in October to the 1st Sunday in November. Then the difference is only 5 hours, so 12 noon in Berlin is 7 a.m. in New York. In 2026 this applied from 25 October to 1 November.

In Germany, summer time 2026 ended on Sunday, 25 October 2026. The next change is on Sunday, 28 March 2027: clocks go forward from 2 to 3 a.m. and the night is one hour shorter. Standard time returns on Sunday, 31 October 2027, when clocks go back from 3 to 2 a.m. The rule: summer time starts on the last Sunday in March and ends on the last Sunday in October.

UTC (Coordinated Universal Time) is the reference time from which all time zones are offset. It has no daylight saving time. CET (Central European Time) is UTC+1 and applies in Germany in winter, CEST (Central European Summer Time) is UTC+2 and applies from late March to late October. GMT (Greenwich Mean Time) is in everyday use the same as UTC; the United Kingdom uses it as its winter time.

Go via universal time: local time minus your own UTC offset gives UTC, UTC plus the target's offset gives the target time. Example in winter: 12:00 in Berlin (UTC+1) is 11:00 UTC, so 06:00 in New York (UTC−5). What matters is the offset on the specific date, because daylight saving time changes it twice a year in many countries, and not all of them change on the same day.

Thailand (UTC+7), Bali (UTC+8) and Dubai (UTC+4) do not change their clocks. So the difference depends only on German time: in winter Thailand is 6 hours ahead of Germany, in summer 5 hours. Bali is 7 hours ahead in winter and 6 in summer, Dubai 3 and 2 hours respectively.

India uses a single time zone for the whole country, Indian Standard Time (UTC+5:30). It is based on the 82.5° east meridian, which runs roughly through the middle of the country; 82.5° corresponds to exactly 5.5 hours. Compared with Germany that is 4:30 hours in winter and 3:30 in summer. Other zones with odd offsets are Iran (UTC+3:30), Nepal (UTC+5:45), parts of Australia (Adelaide UTC+9:30) and Newfoundland (UTC−3:30).

In March, the times from 02:00 to 02:59 do not exist in Germany; clocks jump straight to 03:00. If you enter 02:30, the converter uses 03:30 summer time. In October the same times occur twice: first in summer time, then again in standard time. The converter takes the first one. For appointments on that night, check the note shown with the result.

Not so far. The European Commission proposed ending clock changes in 2018, and the European Parliament agreed on 26 March 2019. The member states in the Council, however, have not agreed on a common position, above all on whether permanent summer or standard time should apply. Directive 2000/84/EC with two changes a year therefore still applies (as of October 2026).

In the meeting planner, choose up to four locations, the working hours and the length. The planner shows every window that falls within working hours everywhere and suggests the slot with the most buffer. With 9-to-5 working hours, Berlin, London and New York overlap between 3 and 5 p.m. German time, for example. If there is no overlap, as with Berlin, New York and Tokyo, it names the fairest compromise.

From the IANA time zone database (tz database) that operating systems and browsers use worldwide. It is updated several times a year when countries change their rules, e.g. Mexico, which largely abolished daylight saving time in 2022. The converter uses your browser's copy; if your browser is up to date, so are the rules. Nothing is sent to a server.
