Question 1

What time is it in New York when it is 12 noon in Germany?

Accepted Answer

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.

Question 2

When is the next clock change?

Accepted Answer

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.

Question 3

What do UTC, CET and CEST mean?

Accepted Answer

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.

Question 4

How do I calculate a time difference myself?

Accepted Answer

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.

Question 5

What is the time difference to Thailand, Bali and Dubai?

Accepted Answer

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.

Question 6

Why does India have a half-hour time difference?

Accepted Answer

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).

Question 7

What happens to times on the night of a clock change?

Accepted Answer

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.

Question 8

Is the EU abolishing daylight saving time?

Accepted Answer

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).

Question 9

How do I find a meeting time across several time zones?

Accepted Answer

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.

Question 10

Where does the converter get its time zones and DST rules from?

Accepted Answer

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.
