Singapore is 2½ hours ahead of India every day of the year: 9:00 AM in Chennai is 11:30 AM in Singapore, and 6:00 PM in Singapore is 3:30 PM in India. Neither country uses daylight saving, so the difference never changes.

Close neighbors in business
Singapore is one of the largest sources of foreign investment into India and a regional base for Indian companies expanding into Southeast Asia. People of Indian descent make up close to a tenth of Singapore's resident population, and Tamil is one of the country's four official languages. Since 2023, India's UPI and Singapore's PayNow have been linked, so money sent between the two arrives in seconds.
The time gap barely affects scheduling. A Singapore office day of 9:00 AM–6:00 PM equals 6:30 AM–3:30 PM in India, so the overlap is the Indian working morning and early afternoon. Teams usually hold joint calls between 10:00 AM and 1:00 PM IST, which is 12:30–3:30 PM in Singapore.
Why Singapore is on UTC+8
By longitude Singapore would fit UTC+7, but since January 1, 1982 it has used UTC+8 to match Malaysia and the major financial centers of East Asia. That choice makes sunrise in Singapore around 7:00 AM and sunset around 7:00 PM all year. Malaysia shares the same clock, so Kuala Lumpur is also 2½ hours ahead of India.
Flights from Chennai or Bengaluru to Singapore take about four hours; you lose 2½ hours on the way out and gain them back on the return. For India against a zone that does change its clocks, see IST to AEST.
