Convert time from IST to SGT. Enter any time to see the equivalent SGT time, compare current IST and SGT times side by side, and find overlapping business hours for calls and meetings.
Use this IST to SGT converter to compare India and Singapore time, check the 2 hours and 30 minutes gap, and confirm the right slot for calls, handoffs, and deadlines. Good overlap starts around 9:00 AM IST / 11:30 AM SGT.
Converting between India Standard Time and Singapore Time means accounting for a 2 hours and 30 minutes gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in India Standard Time (UTC +5:30) that you want to convert. Hit "Now" to load the current ist time instantly, or use "+1h" to step forward and compare.
The equivalent Singapore Time (UTC +8) time appears immediately. Since sgt is 2 hours and 30 minutes ahead of ist, most daytime conversions stay on the same calendar day.
Click "Copy Time" to grab the sgt result for your calendar or message. Use "+1d" to check how the conversion shifts across dates — useful when Daylight Saving Time changes the gap.
When someone in India suggests 9:00 AM ist, that's 11:30 AM sgt. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night ist times can land on a different date in sgt because of the 2 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.
The half-hour offset between ist (UTC +5:30) and sgt (UTC +8) 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.
Product launches, sports matches, and webinars are often announced in ist. Convert the event time to sgt so you know exactly when to tune in — with a 2 hours and 30 minutes difference, a morning event in India falls during work hours in Singapore.

IST is 2.5 h behind SGT — one of the cleanest zone conversions in Asia. Practical: 11 AM IST = 1:30 PM SGT (both mid-workday), 4 PM IST = 6:30 PM SGT (end of Singapore day, mid-afternoon India). Full-day overlap. This is the "Southeast Asia regional HQ meets India tech centre" corridor — Grab, Ola, Zomato, Shopee, and every regional VC has both endpoints of this pair on standing weekly calendar invites.
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.
Singapore / KL / Manila business hub — Southeast Asia's regional HQ zone. Business hours 9 AM – 6 PM SGT. Overlaps well with India (early SGT afternoon = late IST afternoon) and Australia (late morning SGT = early afternoon AEDT). Long time gap with the US means transactions bridging Singapore / SF are usually async.
Time gap: SGT is 2.5 hours ahead of IST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
