Examples

10:00 IST = 04:30 UTC

20:00 IST = 09:30 EST (same day)

09:00 PST = 22:30 IST

03:00 IST = 16:30 EST on the previous day

IST and daylight saving

India Standard Time is UTC+5:30 all year and does not use daylight saving time. The US, UK and Europe move clocks forward in summer, so the gap with India shrinks by one hour: New York is 10.5 hours behind IST in winter (EST) and 9.5 hours behind in summer (EDT). This converter uses standard-time offsets, so subtract one hour from the gap during the other region's summer time.

Tips for accurate results

  • Schedule international calls in both time zones.
  • Check whether the other country is on daylight saving time.
  • Use 24-hour time to avoid AM/PM confusion.
