Time zone converter

Convert a time between time zones

Runs in your browser. Nothing is uploaded.

How it works

To convert a time, work out the moment in UTC, then add the offset of each place. India is 5 hours 30 minutes ahead of UTC, and New York is 5 hours behind in winter. So 09:00 in India is 22:30 the previous day in New York. Daylight saving is included.

local time = UTC time + zone offset

Your browser’s time zone database knows when each place changes its clocks, so we use the right offset for the date you choose.

If a clock change skips or repeats your time, we say so.

Worked example. 09:00 in India on 15 Jan 2026 is 22:30 the day before in New York, 03:30 in London and 07:30 in Dubai.

Examples

Place	Time when it’s 09:00 in India	Offset
New York	22:30 −1 day	UTC−05:00
London	03:30	UTC+00:00
Dubai	07:30	UTC+04:00

Questions

What is IST?

India Standard Time is UTC+5:30 all year. India doesn’t use daylight saving.

Why does the difference change during the year?

Places such as New York and London move their clocks, but India doesn’t.

Why is Nepal 15 minutes off from India?

Nepal uses UTC+5:45, one of the few offsets that isn’t a whole or half hour.

How do I schedule a meeting across time zones?

Enter the time in one city and read it in the others. Check both dates too, because the day can change across zones.

What is the difference between UTC and GMT?

For everyday use, they show the same time. UTC is the modern time standard, while GMT is a time zone used in the UK in winter.
