IST (India Standard Time) is 1.5 hours ahead of GST (Gulf Standard Time). This means when it's 12:00 PM in Dubai (GST), it's 1:30 PM in Mumbai (IST).
The best time to call from GST to IST is during overlapping business hours. For GST callers, schedule between 9:00 AM - 12:00 PM GST to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Gulf Standard Time (UTC+4) and India Standard Time (UTC+5:30) may have different DST schedules.
GST includes cities like Dubai. IST includes cities like Mumbai. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
