Amsterdam is 3 hours 30 minutes behind Mumbai for most of the year: when it is 11:00 am in Mumbai it is 7:30 am in Amsterdam. In offset terms Mumbai is on UTC+05:30 and Amsterdam is on UTC+01:00 in January, and UTC+05:30 and UTC+02:00 in July. The converter above works from your browser’s own time zone data, so the figure it shows is the one in force today rather than the one that was in force when this page was written.

The difference is not constant, because only one of the two cities observes daylight saving. In 2026, Mumbai does not change at all and Amsterdam changes on 29 March and 25 October. That leaves 3 distinct periods in the year, and the table below gives the exact dates. It is the short windows that catch people out: a recurring call booked in one city’s clock silently moves in the other’s.

For arranging anything, the number that matters is the overlap. Mumbai works 10:00 to 18:30 and Amsterdam works 09:00 to 17:30, which leaves 12:30 to 18:30 in Mumbai — 09:00 to 15:00 in Amsterdam — as the window when both are open. That is 6 hours of shared working time. Both cities work Monday to Friday, so only the clock has to be reconciled.

Two local details worth knowing. India runs on a single half-hour zone, UTC+05:30, for the whole country and does not observe daylight saving. Dutch meetings start on the minute and finish on the minute, and a four-day week is common enough that Fridays are worth checking.

The safest way to write a time for these two cities is to give both, as in "11:00 Mumbai / 07:30 Amsterdam", or to give the UTC offset. Abbreviations are the trap: Mumbai is on IST for part of the year and IST for the rest, and the same three letters are reused in other parts of the world for entirely different offsets.

How it works, step by step

  1. Enter a time in Mumbai using the 24-hour hour box and the minute box — 15:30 is hour 15, minute 30.
  2. Your browser reports the UTC offset in force in Mumbai and in Amsterdam for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 3.5 hour rule.
  3. The second offset minus the first gives the difference, which is added to the time you entered. A result past midnight is marked as the next or previous day, because that is where most conversion mistakes live.
  4. The panel also shows the current time in both cities, the date in Amsterdam, and whether the two offices are open at the same moment.

Worked examples

10:00 in Mumbai

10:00 in Mumbai is 06:30 in Amsterdam — before the working day starts in Amsterdam. In 12-hour terms, 10:00 am against 6:30 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.

12:00 in Mumbai

12:00 in Mumbai is 08:30 in Amsterdam — before the working day starts in Amsterdam. In 12-hour terms, 12:00 pm against 8:30 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.

17:30 in Mumbai

17:30 in Mumbai is 14:00 in Amsterdam — inside Amsterdam office hours. In 12-hour terms, 5:30 pm against 2:00 pm. Both offices are open at that moment, so it is a slot either side can accept.

The 1 January window, when the usual answer is wrong

Between 1 January and 28 March the difference is -04:30 rather than -03:30, because one city has changed its clocks and the other has not. In that window 11:00 in Mumbai is 06:30 in Amsterdam, an hour away from where a fixed-offset table would put it.

How to read your score

0–5.999Middle of the night in AmsterdamBetween midnight and 06:00 in Amsterdam. Nothing scheduled here will be answered; if the time you entered lands in this window, the meeting has to move or one side has to work outside hours.
6–9Early morning in AmsterdamBefore the working day starts in Amsterdam, which customarily begins at 09:00. Reachable by phone for something urgent, not for a routine call.
9–17.5Office hours in AmsterdamInside the 09:00 to 17:30 working day in Amsterdam. Whether it also suits Mumbai depends on the overlap window given above.
17.5–24Evening in AmsterdamAfter 17:30, when the Amsterdam working day has finished. Fine for a message, poor for a meeting, and it gets worse the later it runs.

Frequently asked questions

How many hours behind Mumbai is Amsterdam?

Amsterdam is 3 hours 30 minutes behind Mumbai for most of 2026, so 09:00 in Mumbai is 05:30 in Amsterdam. The difference changes during the daylight saving changeovers, and the table on this page lists every period in the year with its exact dates.

What is 2 pm Mumbai time in Amsterdam?

10:30 am, inside Amsterdam office hours. In 24-hour form 14:00 in Mumbai is 10:30 in Amsterdam, and that is a normal working moment in both cities.

What is the best time to call between Mumbai and Amsterdam?

Anywhere between 12:30 and 18:30 Mumbai time, which is 09:00 to 15:00 in Amsterdam. Both offices are open across that whole window — 6 hours of it. If you want one answer rather than a range, 15:30 in Mumbai is the middle of the overlap.

Is Amsterdam ahead of or behind Mumbai?

Amsterdam is behind. Mumbai is at UTC+05:30 and Amsterdam is at UTC+01:00 in mid-January, and UTC+05:30 and UTC+02:00 in mid-July. The clock moves back going from Mumbai to Amsterdam, which is why Mumbai reaches the end of its working day first.

Do Mumbai and Amsterdam change their clocks on the same date?

No. In 2026, Mumbai does not change its clocks at all, and Amsterdam changes on 29 March 2026 and 25 October 2026. That is why the difference between them takes 2 different values across the year rather than one.

What do the abbreviations for Mumbai mean?

Mumbai is on IST in winter and IST in summer, while Amsterdam uses CET and CEST. Abbreviations are the least reliable way to write a time: several are ambiguous between regions, and the summer and winter forms are an hour apart. A UTC offset, or the time given in both cities, cannot be misread.

Does this converter stay correct after the clocks change?

Yes. It does not use a stored number for the difference. Each time you change a value it asks your browser for the UTC offset that Asia/Kolkata and Europe/Amsterdam are on at that moment, using the IANA time zone database that ships with your operating system, and takes the difference. The tables on this page are computed from the same database for 2026.
