How to convert IST to SGT
Here IST means India Standard Time, UTC+5:30 all year; SGT means Singapore Time, UTC+8 all year. So SGT is 2 h 30 min ahead of IST all year. Two 9-to-5 working days overlap by 5 h 30 min all year.
From India, Singapore is where many Asia-Pacific headquarters, regional finance teams and data centres sit, and IST to SGT tells you how much of their day is left. The overlap is generous: from 9:00 am to 2:30 pm in India, both offices are open. After that, Singapore is wrapping up while India still has half a working day to go.
The sum is the same on every date, because neither side moves its clocks: add 2 h 30 min. The half hour still trips people up, since a meeting on the hour in India always lands at half past in Singapore. Flights leave on local time, so a departure at 11:30 pm from Chennai and an arrival given in Singapore time need this conversion to count the hours in the air.
Rule of thumb: Add 2½ hours to Indian time: 4:00 pm IST is 6:30 pm in Singapore, and 11:30 am IST is 2:00 pm there.

Meeting planner: best times for IST and SGT
The easiest meetings fall where both working days overlap, shaded dark on the bar. The lighter shading is still between 7 am and 9 pm on both clocks, so one side starts early or stays late.
All year: IST and SGT
- Both at work: 9:00 am to 2:30 pm IST is 11:30 am to 5:00 pm SGT (5 h 30 min).
- Early or late for one side: 7:00 am to 9:00 am IST is 9:30 am to 11:30 am SGT (2 h); 2:30 pm to 6:30 pm IST is 5:00 pm to 9:00 pm SGT (4 h).
