Every hour as its own page

UTC to IST — questions

What time is it in IST when it is UTC now?
IST is currently 04:58 on Thursday, 13 August 2026 (IST, UTC+05:30), while UTC is 23:28 (UTC+00:00). That is 5.5 hours ahead of the source clock right now.
How many hours ahead is IST of UTC?
5.5 hours at this moment. The gap is not constant across the year: Coordinated Universal Time and India Standard Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is IST on daylight saving time right now?
No. Asia/Kolkata is on IST (UTC+05:30) at the moment.
Does IST observe daylight saving time?
No. Asia/Kolkata stays on UTC+05:30 all year, so the difference from UTC only moves when UTC itself changes.
What is the best time to schedule a call between UTC and IST?
There are 4 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00–13:00 UTC, which is 14:30–18:30 IST. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for IST in code?
Use Asia/Kolkata. Abbreviations like IST are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+05:30 instead will be wrong the moment the rules change.
