When converting from IST to GST, the key reference points to remember are: 9:00 AM IST equals 7:30 AM GST, 12:00 PM noon IST equals 10:30 AM GST, and 5:00 PM IST equals 3:30 PM GST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across IST and GST
For professionals scheduling meetings between IST and GST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 1 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. GST does not observe DST, staying at UTC+4 year-round.
