Civil time & global coordination
Convert India Time to World Time
Convert a dated time between India and a named world city. Both directions include local dates and daylight-saving rules; copy the result or create a 30-minute calendar invitation.
Date-aware time converter
Avoid scheduling mistakes
| Situation | What to check |
|---|---|
| Midnight crossing | Read the local date beside the result. A deadline may land on the previous or next day. |
| Spring clock change | Some local times are skipped. The tool rejects a time that does not exist. |
| Autumn clock change | An hour can repeat. Choose the first or second occurrence when prompted. |
| Recurring meetings | Use a named city timezone in the calendar invitation, rather than a fixed offset. |
Example: 18:00 IST on 15 January 2026 is 12:30 in London. On 15 July it is 13:30 because London has changed its clocks.
UTC and half-hour offsets
Choose UTC as a destination or source when a deadline uses the coordinated time reference. The converter also includes Kathmandu’s quarter-hour offset and named city rules; it does not round every timezone to a whole hour.
Calendar events use an unambiguous UTC instant. For a repeated local clock hour, choose its occurrence before downloading the event.
