Time zone facts for Mumbai
- IANA time zone:
Asia/Kolkata - Standard offset: UTC+5:30
- Daylight saving: not observed — Mumbai keeps UTC+5:30 all year.
- January / July offset: UTC+5:30 / UTC+5:30
- Offset as of September 2026: UTC+5:30 — daylight saving not in effect
- Next clock change: none scheduled within the next 15 months (as of September 2026)
How Mumbai's offset moves through the year
Mumbai keeps one offset, UTC+5:30, on every day of the year. There is no January-to-July swing — the January and July offsets are both UTC+5:30 — and as of September 2026 no clock change is scheduled within the next 15 months.
That does not make Mumbai's time differences fixed. The gap to any partner that observes daylight saving still moves twice a year — on the partner's transition dates, not on any date of Mumbai's own. A meeting fixed at a Mumbai wall-clock time drifts by the partner's shift amount on each of those dates, and a meeting fixed on the partner's clock drifts by the same amount on Mumbai's. The only pairs that never move are with other cities that also keep one offset all year.
Mumbai's offset is not a whole number of hours: as of September 2026 it is UTC+5:30. The difference to any whole-hour zone therefore always ends in :30, and rounding it to the nearest hour puts a meeting 30 minutes off. Every difference on this page is stated to the minute for that reason.
The gap to London, New York, and Tokyo across the year
The differences below were computed at build time by scanning the coming twelve months of the IANA time zone database for each pair, locating every instant at which either city changes its clocks, and reading the gap on each side of it. "As of September 2026" is the gap today; "over the year" is the full range the pair takes before the same month comes round again, from Mumbai's point of view.
| Reference | Mumbai is, as of September 2026 | Over the coming year | Why |
|---|---|---|---|
| London | 4:30 hours ahead | 4:30 hours ahead to 5:30 hours ahead | only London changes its clocks |
| New York | 9:30 hours ahead | 9:30 hours ahead to 10:30 hours ahead | only New York changes its clocks |
| Tokyo | 3:30 hours behind | does not change | neither side changes its clocks |
Two things are visible at once: the gap to Tokyo is one number all year, while the gap to London and New York is not. The mechanism in each case is set out below, with the exact instants at which the gap moves.
Mumbai and London
As of September 2026, Mumbai is 4:30 hours ahead of London. London changes its clocks for daylight saving and Mumbai does not. Each London transition therefore moves the gap by the full size of that shift, and nothing ever moves it back except the next London transition. The gap changes twice in the coming twelve months, always on London's dates — Mumbai's calendar plays no part.
- From Sunday, October 25, 2026 at 6:30 AM (Mumbai time), when London changes clocks: Mumbai is 5:30 hours ahead of London.
- From Sunday, March 28, 2027 at 6:30 AM (Mumbai time), when London changes clocks: Mumbai is 4:30 hours ahead of London.
Mumbai and New York
As of September 2026, Mumbai is 9:30 hours ahead of New York. New York changes its clocks for daylight saving and Mumbai does not. Each New York transition therefore moves the gap by the full size of that shift, and nothing ever moves it back except the next New York transition. The gap changes twice in the coming twelve months, always on New York's dates — Mumbai's calendar plays no part.
- From Sunday, November 1, 2026 at 11:30 AM (Mumbai time), when New York changes clocks: Mumbai is 10:30 hours ahead of New York.
- From Sunday, March 14, 2027 at 12:30 PM (Mumbai time), when New York changes clocks: Mumbai is 9:30 hours ahead of New York.
Mumbai and Tokyo
As of September 2026, Mumbai is 3:30 hours behind Tokyo. Neither Mumbai nor Tokyo changes its clocks, so the difference is the same number on every day of the year. There is nothing to remember and nothing to re-check in spring or autumn.
Ranked by how many of the 365 scanned days each gap spends at its most common value, from Mumbai's point of view: Tokyo 365 (it never moves), New York 232 (9:30 hours ahead), and London 211 (4:30 hours ahead).
Working hours that overlap
Assume a 9:00 AM to 5:00 PM working day in Mumbai and the same in each reference city. The overlap is then a plain consequence of the gap, and it changes whenever the gap does — so where a pair takes more than one gap during the year, both readings are given. As of September 2026:
- London: 3 hours 30 minutes — 1:30 PM to 5:00 PM in Mumbai, which is 9:00 AM to 12:30 PM in London. When Mumbai is 5:30 hours ahead of London — the rest of the year — the overlap is 2 hours 30 minutes — 2:30 PM to 5:00 PM in Mumbai, which is 9:00 AM to 11:30 AM in London.
- New York: none at any gap the pair takes during the year — a 9:00 AM to 5:00 PM day in Mumbai never meets a 9:00 AM to 5:00 PM day in New York.
- Tokyo: 4 hours 30 minutes — 9:00 AM to 1:30 PM in Mumbai, which is 12:30 PM to 5:00 PM in Tokyo.
The 9-to-5 window is a convention, not a fact about anyone's hours. The Meeting Planner takes each participant's actual working hours and evaluates the overlap for the specific date, so a slot chosen in one season is still checked against the other side's clock in the next.
Mumbai time — frequently asked questions
What time zone is Mumbai in?
Mumbai uses the IANA time zone Asia/Kolkata. Its standard offset is UTC+5:30, all year round.
Does Mumbai observe daylight saving time?
No. Mumbai keeps UTC+5:30 throughout the year, so its clocks never shift for daylight saving.
When do the clocks next change in Mumbai?
As of September 2026, no clock change is scheduled for Mumbai within the next 15 months — the offset stays UTC+5:30.
How does Mumbai time compare with UTC, London, and New York?
As of September 2026, Mumbai is on UTC+5:30 and 4:30 hours ahead of London and 9:30 hours ahead of New York. These differences shift whenever either side changes its clocks for daylight saving.
How far ahead of or behind New York is Mumbai over the year?
As of September 2026, Mumbai is 9:30 hours ahead of New York. Over the coming twelve months the difference ranges from 9:30 hours ahead to 10:30 hours ahead, changing twice, because New York changes its clocks for daylight saving and Mumbai does not. The dates of each change are listed on this page under "Mumbai and New York".
Why does a standing meeting between Mumbai and London move by 1 hour during the year?
Because London changes its clocks for daylight saving and Mumbai does not. A meeting fixed at one wall-clock time in Mumbai lands 1 hour earlier or later on London's clock after each London transition, and a meeting fixed in London does the same on Mumbai's clock. As of September 2026, the next such change is on Sunday, October 25, 2026 at 6:30 AM (Mumbai time). Decide which city's calendar the meeting is anchored to, and expect the other side to move twice in the coming year.
Business-hours overlap
When it is 9:00 AM in Mumbai (as of September 2026), it is 4:30 AM in London, 11:30 PM the previous day in New York, and 12:30 PM in Tokyo. These readings shift when any of the cities changes its clocks — the Meeting Planner computes the overlap for your exact date.
