Each India hour and the Singapore time at that moment. The rows from 9:00 AM to 5:00 PM India time are in full color.

Why the gap is 2 h 30 min

Singapore sits at roughly 104° east, which would suggest a clock about seven hours ahead of UTC. It uses UTC+8 instead, the same as Malaysia, Hong Kong and China, which keeps it aligned with its main trading partners in the region.

India's UTC+5:30 is a half-hour offset, so any conversion with a whole-hour zone ends on the half hour. The IANA time zone database records both offsets and confirms that neither zone has scheduled clock changes.

Overlap for a working day

The two countries share most of the office day. Singapore's 9:00 AM is India's 6:30 AM, and Singapore's 5:00 PM is India's 2:30 PM, so a call between 11:30 AM and 5:30 PM Singapore time sits inside normal hours on both sides.

The live clocks for Kuala Lumpur and Delhi show the same relationship. For other UTC+8 contacts, the Manila and Perth pages give the same answer.

Easy parts

  • Business hours overlap for six hours every working day.
  • No daylight saving on either side, so recurring meetings never drift.
  • The same result works for Malaysia, Hong Kong and the Philippines.

Things to watch

  • Singapore's late afternoon is India's lunchtime.
  • The half-hour step makes mental maths a little slower.
  • Friday-evening deadlines in Singapore arrive while India is still mid-afternoon.

IST to SGT questions

How far ahead of India is Singapore?

Singapore is 2 hours 30 minutes ahead of India all year.

If it is 9:00 AM in Singapore, what time is it in India?

It is 6:30 AM in India.

Does Singapore use daylight saving time?

No. Singapore keeps UTC+8 all year, and India keeps UTC+5:30, so the gap never changes.

Does Kuala Lumpur share Singapore's time?

Yes. Peninsular Malaysia and Singapore both use UTC+8, so an India-to-Singapore conversion also gives Kuala Lumpur time.

What other places share Singapore's clock?

Hong Kong, mainland China, Taiwan, the Philippines and Perth in Western Australia are all on UTC+8.
