Why Choose Our ist to gst Converter

Align ist–gst Meetings Instantly

When someone in India suggests 11:00 AM ist, that's 9:30 AM gst. This converter shows the overlap so both sides agree on one slot — no back-and-forth.

Spot Date-Line Shifts at a Glance

Late-night ist times can land on a different date in gst because of the 1 hours and 30 minutes offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.

Handles DST Transitions Automatically

The half-hour offset between ist (UTC +5:30) and gst (UTC +4) already makes mental math tricky — add Daylight Saving Time and the gap can shift further. This converter uses live UTC offsets, so you're always accurate.

Never Miss a ist-Timed Event

Product launches, sports matches, and webinars are often announced in ist. Convert the event time to gst so you know exactly when to tune in — with a 1 hours and 30 minutes difference, a morning event in India falls during work hours in United Arab Emirates.

The two zones in context

IST vs GST — cities and working rhythm

IST — India Standard Time
Primary cities: Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata

Indian business hours run 10 AM – 7 PM IST typically; IT / BPO shifts commonly extend to cover US and UK working hours, so 3:30 PM – 12:30 AM IST (US overlap) and 12:30 PM – 9 PM IST (UK overlap) are the two second shifts you see most often. Weekend is Saturday-Sunday for most private-sector employers.
