How this works
Method
Here IST means India Standard Time, UTC+5:30 all year; UTC means Coordinated Universal Time, which never changes. So UTC is 5 h 30 min behind IST all year. Two 9-to-5 working days overlap by 2 h 30 min all year. Full method

- 15 more conversion pages (IST to CST, BST to IST, SGT, GST, JST, MST and more); each conversion page shows all 24 hours with working hours shaded, and its best meeting times.
- The pickers find about a thousand more cities, states and countries (Seattle, Bangalore, Texas), and each conversion page names the next clock change on either side.
- The converter opens on the time now, live, with a Now choice beside the time, and the main converter starts from your own time zone.

How to convert IST to UTC
Here IST means India Standard Time, UTC+5:30 all year; UTC means Coordinated Universal Time, which never changes. So UTC is 5 h 30 min behind IST all year. Two 9-to-5 working days overlap by 2 h 30 min all year.
Developers, analysts and support engineers in India convert IST to UTC all day: to set a cron job or a cloud alarm that expects UTC, to match an Indian customer’s complaint against a server log, or to tell a global team when a release goes out. Because India has no daylight saving time the sum never changes: take away 5 h 30 min, and step back to the previous date for any time before 5:30 am.
The half hour is the usual source of bugs. A job meant to run at 9:00 am in India must be scheduled for 03:30 UTC, not 03:00 or 04:00, and many scheduling tools only offer whole hours in their quick pickers. When you write a time for others, give the offset with it: 2026-10-10T14:00:00+05:30 and 2026-10-10T08:30:00Z are the same moment, and either one can be read anywhere without guessing.
Rule of thumb: Subtract 5 hours 30 minutes, moving to the day before for times earlier than 5:30 am: 3:00 am IST is 9:30 pm UTC the previous day.
UTC = IST −5:30
- Internet timestamps carry their offset from UTC as +hh:mm or −hh:mm, so Indian time is written +05:30, and a time in UTC itself can end in Z. Source: RFC 3339, Date and Time on the Internet: Timestamps.
Meeting planner: best times for IST and UTC
The easiest meetings fall where both working days overlap, shaded dark on the bar. The lighter shading is still between 7 am and 9 pm on both clocks, so one side starts early or stays late.
All year: IST and UTC
- Both at work: 2:30 pm to 5:00 pm IST is 9:00 am to 11:30 am UTC (2 h 30 min).
- Early or late for one side: 12:30 pm to 2:30 pm IST is 7:00 am to 9:00 am UTC (2 h); 5:00 pm to 9:00 pm IST is 11:30 am to 3:30 pm UTC (4 h).
