Singapore to India Time Difference: SGT to IST Conversion Guide
Singapore Standard Time (SGT) is UTC+8. India Standard Time (IST) is UTC+5:30. The difference is exactly 2 hours and 30 minutes, with Singapore ahead. When it is 10:00 AM in Singapore, it is 7:30 AM in India. When it is 6:00 PM in Singapore, it is 3:30 PM in India.
Neither Singapore nor India observes daylight saving time. This means the 2.5-hour gap is fixed year-round — no seasonal adjustments, no confusion about which week the clocks change. If you memorise the offset once, it works every day of the year.
Why This Time Zone Pair Matters
Singapore is a major hub for Indian IT companies and financial services. Infosys, TCS, Wipro, and HCL all have significant Singapore offices. Indian banks operate GIFT City international branches coordinated with Singapore trading desks. The tech corridor between Bangalore and Singapore is one of the busiest in Asia, and the 2.5-hour offset means substantial working-hour overlap.
Beyond business, Singapore has a large Indian diaspora — roughly 9% of the resident population. Family calls, festival coordination, and travel planning between the two countries are daily occurrences.

Best Meeting Times for Singapore and India Teams
The 2.5-hour difference gives you nearly a full working day of overlap, which is rare for cross-border time zone pairs.
- Morning overlap: 9:00 AM – 12:00 PM SGT is 6:30 AM – 9:30 AM IST. Works if the India side starts early, but 6:30 AM is too early for most teams.
- Sweet spot: 10:30 AM – 5:00 PM SGT is 8:00 AM – 2:30 PM IST. Both sides are fully in their working day.
- Late overlap: 5:00 PM – 7:30 PM SGT is 2:30 PM – 5:00 PM IST. Singapore is winding down, India has the full afternoon ahead.
The ideal window for recurring meetings is 11:00 AM – 2:00 PM SGT (8:30 AM – 11:30 AM IST). Both sides are alert, past their morning routines, and nowhere near end-of-day fatigue.
Quick Mental Math
To convert SGT to IST: subtract 2 hours and 30 minutes. To convert IST to SGT: add 2 hours and 30 minutes. Since neither country changes clocks, this works every single day of the year.
No Daylight Saving Time — Keeping It Simple
One of the biggest advantages of the Singapore-India time zone pair is the complete absence of daylight saving time. Countries like the US, UK, and Australia shift their clocks twice a year, which means their offsets with other countries change seasonally. Singapore and India never do this.
If you schedule a recurring 11:00 AM SGT / 8:30 AM IST standup, it stays at exactly those times in January, April, July, and October. No need to check whether clocks changed, no missed meetings because someone forgot the spring-forward adjustment.
Common Scenarios
- Flight arrivals: A direct Singapore-to-Delhi flight takes about 5.5 hours. If you depart at 10:00 AM SGT, you land around 1:00 PM IST (10:00 AM + 5.5 hours flight − 2.5 hours time zone difference).
- Stock markets: SGX (Singapore Exchange) opens at 9:00 AM SGT, which is 6:30 AM IST. NSE/BSE (India) opens at 9:15 AM IST, which is 11:45 AM SGT. Both exchanges are open simultaneously from 11:45 AM to 5:00 PM SGT.
- Cricket matches: An IPL evening match starting at 7:30 PM IST is 10:00 PM SGT — late but watchable for the Singapore crowd.
