Daylight saving is handled for the date you pick, so the gap between two cities can change during the year. Times shown in your browser's data may differ for very recent rule changes.

Booking meetings across time zones without mistakes

The world is divided into time zones, and the confusion starts when daylight saving shifts them. India does not change its clock, but the US, UK and most of Europe do, so the gap with those places moves twice a year.

India's time is UTC+5:30. So 10:00 in India is 04:30 UTC. That is 08:30 in Dubai, 12:30 in Singapore and 13:30 in Tokyo, the same moment with different clocks. In London it is 04:30 in winter and 05:30 in summer.

The gap with the US is trickier. In winter, New York is 10.5 hours behind India. In summer it is 9.5 hours behind. Several times a year, a meeting set in the evening for you lands on a different morning than before, and an unsuspecting colleague may arrive an hour early.

Two habits help. State the time with the zone and date in every invite, for example 10:00 IST on 4 November. And before the clocks change in March and October or November, check recurring meetings, because they may move for one side but not the other.

What this calculator does not account for

  • Recent changes to daylight saving rules in your device.
  • Cities not in the list.
  • Local clocks that are set differently.

How this is calculated

Formula: Same instant, different clocks

local time =UTC + zone offset (on that date)

What the symbols mean

  • UTCThe common reference time.
  • offsetIndia is UTC+5:30 all year. Other zones shift when daylight saving starts or ends.

Good to know

  • The tool uses your device's built-in time zone database.
  • The day name shows when the date is different from where you started.

Each example is worked out by the same code as the calculator above.

10:00 India time

04:30 UTC, 08:30 in Dubai, 12:30 in Singapore, 13:30 in Tokyo. New York and London depend on daylight saving on that date.

Questions

What is the time difference between India and the US?

New York is 10.5 hours behind India in the US winter and 9.5 hours behind in the US summer. Use the converter for the exact date.

Does India have daylight saving time?

No. India stays at UTC+5:30 all year, so the gap with the US and Europe changes in March and November.

Why is there a half-hour in some zones?

India, parts of Australia and a few others use half-hour offsets from UTC.

Which date should I enter?

The date in the starting city. A late evening time can fall on the next day elsewhere.
