GST (Gulf Standard Time) is 1 hour and 30 minutes behind IST (Indian Standard Time). This means when it's 12:00 PM in Mumbai (IST), it's 10:30 AM in Dubai (GST).
The best time to call from IST to GST is between 8:30 AM and 5:00 PM IST, which corresponds to 7:00 AM to 3:30 PM GST. This ensures both parties are within standard business hours.
No, the time difference remains constant at 1 hour 30 minutes. India does not observe Daylight Saving Time, and the UAE also does not observe DST, so the offset stays consistent year-round.
IST cities include Mumbai, Delhi, Bangalore, Kolkata, and Chennai. GST cities include Dubai, Abu Dhabi, and Sharjah in the United Arab Emirates.
India uses UTC+5:30, which is a 30-minute offset from standard hour-based time zones. This was chosen to provide a single time zone for the entire country while being close to the mean solar time of India's geographic center.
