Converting India Standard Time to Coordinated Universal Time
India Standard Time (IST) and Coordinated Universal Time (UTC) are separated by a 5 hours and 30 minutes time difference. UTC is 5 hours and 30 minutes behind IST. IST is UTC+5:30, used in India, Sri Lanka, while UTC is UTC+0.
When converting from IST to UTC, the key reference points to remember are: 9:00 AM IST equals 3:30 AM UTC, 12:00 PM noon IST equals 6:30 AM UTC, and 5:00 PM IST equals 11:30 AM UTC. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across IST and UTC
For professionals scheduling meetings between IST and UTC, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 5 hours and 30 minutes difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
IST does not observe Daylight Saving Time, maintaining UTC+5:30 year-round. UTC does not observe DST, staying at UTC+0 year-round.
