About this tool
This page opens the converter with UTC preselected as the source and India as the target — the moment it loads you see the current UTC time expressed as India Standard Time, and any other timestamp takes one edit.
IST is a fixed UTC+5:30 year-round: India observes no daylight saving, so the offset never moves — but the half-hour step is what trips people up when adding it in their head. 12:00 UTC is always 17:30 in India, whatever the season; the converter does the +5:30 arithmetic (and the date rollover near midnight) for you.
Beyond this pair, the full tool converts between any two IANA time zones for any date, entirely locally in your browser.
Example. 12:00 in America/New_York on 15 January 2026 is 22:30 in Asia/Kolkata, GMT+05:30. On 15 July 2026 the same clocks read 21:30.
Limit. 02:30 in New York on 8 March 2026 does not exist and is rejected. The fall-back hour resolves to one instant. Zones come from the browser's IANA list.
