Singapore Time to India Time: SGT to IST Hour Table

Quick answer: Singapore is 2 hours 30 minutes ahead of India, all year round. Singapore Standard Time (SGT) is UTC+8 and Indian Standard Time (IST) is UTC+5:30. To change Singapore time to India time, subtract 2 hours 30 minutes. To change India time to Singapore time, add 2 hours 30 minutes. For example, 9:00 AM in Singapore is 6:30 AM in India, and 9:00 AM in India is 11:30 AM in Singapore.

This is one of the easiest time differences for Indian travellers, students, professionals and families to manage. Neither country changes its clocks for daylight saving, so the 2 hours 30 minutes gap is the same in January and in July. This guide gives you the full hour-by-hour tables in both directions, the other countries that share Singapore time, the best hours to call or hold a meeting, and the small mistakes that still catch people out, mostly around midnight. Last updated 11 October 2026.

Key takeaways

• Singapore is ahead of India by 2 hours 30 minutes.
• Singapore uses SGT (UTC+8). India uses IST (UTC+5:30). Neither uses daylight saving time.
• The gap never changes during the year, so you do not need to check the date.
• Singapore to India: subtract 2:30. India to Singapore: add 2:30.
• Malaysia, Hong Kong, the Philippines, Taiwan, mainland China and Perth in Australia also use UTC+8, so they have the same gap from India.
• Be careful after 9:30 PM in India. It is already the next day in Singapore.

Singapore time to India time difference

The time difference between Singapore and India comes from the gap between their standard times. Singapore is at UTC+8. India is at UTC+5:30. Take one from the other and you get 2 hours 30 minutes.

The half-hour part is what confuses people. India is one of the few big countries on a half-hour offset, so the difference is not a round number of hours. A quick way to remember it: add two hours, then add thirty minutes. If it is 4:00 PM in India, add two hours to get 6:00 PM, then thirty minutes to get 6:30 PM in Singapore.

The gap is also stable. Singapore moved to UTC+8 in 1982 and has kept it since. India has used IST all year for decades. So the answer on any date is the same, and you can trust the tables below without checking for clock changes.

Singapore time to IST: hour-by-hour table

Use this table when you know the time in Singapore and want the time in India. The last column tells you when the day changes.

A simple check: if the Singapore time is before 2:30 AM, the India time falls on the previous day. For example, 1:00 AM on Tuesday in Singapore is 10:30 PM on Monday in India.

India time to Singapore time: common times

This table covers the times people most often ask about, such as office hours, interview slots and evening calls.

If the India time is 9:30 PM or later, the Singapore time is already after midnight, so it is the next calendar day. This matters for flight bookings, online exam slots and webinar sign-ups.

Which countries share Singapore time?

Singapore time (UTC+8) is also used in many places that Indians travel to, study in, or work with. All the places below have the same 2 hours 30 minutes gap from India. The table also shows nearby countries with a different gap.

If you are planning a trip across Southeast Asia, the useful point is that Singapore, Kuala Lumpur and Hong Kong all run on the same clock, while Bangkok and Jakarta are one hour behind them. Tokyo and Seoul are one hour ahead.

If you work with the Gulf as well, remember that Dubai is 1 hour 30 minutes behind India, so Singapore is 4 hours ahead of Dubai. Our guide to the India to UAE time difference covers that side.

Best time to call or meet between India and Singapore

Because the gap is only 2 hours 30 minutes, almost the whole working day overlaps. This is much easier than India to the USA or Canada. The windows below work for most office schedules.

Some practical points:

• Business meetings: the best overlap is from 12:00 PM to 6:00 PM in Singapore, which is 9:30 AM to 3:30 PM in India. Both sides are inside normal hours.
• Early meetings: a 9:00 AM start in Singapore is 6:30 AM in India. It works for a quick call, but it is early for most Indian teams.
• Late meetings: a 6:00 PM start in India is 8:30 PM in Singapore. It is fine for a short call, but many Singapore teams will already have left.
• Family calls: evenings are the easiest. 7:00 PM to 10:00 PM in Singapore is 4:30 PM to 7:30 PM in India.
• Public holidays: Singapore and India have different public holidays, so check both calendars before you fix a date.

Examples that show how to convert

These are the questions people usually have.

Example 1: A job interview in Singapore

Your interview is at 10:30 AM Singapore time. Subtract 2 hours 30 minutes: it is 8:00 AM in India. Set your alarm for early morning and test your video link the evening before.

Example 2: A webinar for Indian time

A Singapore company hosts a webinar at 4:00 PM IST. Add 2 hours 30 minutes: it starts at 6:30 PM in Singapore. If you join from India, no change is needed. If you are a speaker in Singapore, plan dinner after the session.

Example 3: A late-night flight

You leave Chennai at 10:00 PM IST and the flight takes about 4 hours 30 minutes. You land at 2:30 AM IST, which is 5:00 AM in Singapore, on the next calendar day. Always check the arrival date on your ticket, because the date can move forward.

Example 4: Midnight in India

It is 11:45 PM on Friday in India. In Singapore it is 2:15 AM on Saturday. A form that closes at midnight Singapore time closes at 9:30 PM India time the day before.

Does the gap ever change?

No. Singapore does not use daylight saving time and India does not use it either. This is a big difference from the UK, the USA, Canada and Australia, where clocks change twice a year and the gap with India moves by an hour. Because of this, a Singapore meeting that was fixed in January does not move in March or November.

The only things that change are the gaps between Singapore and countries that do use daylight saving. For example, the Singapore to UK gap is 8 hours in winter and 7 hours in summer. The India to Singapore gap stays the same. If you also work with the UK, read our guide on UK time to India time, and for Australia see AEST to IST.

Jet lag between India and Singapore

A 2 hours 30 minutes shift is small. Most travellers feel little or no jet lag. If you land in Singapore in the morning, you may feel sleepy a couple of hours earlier than local bedtime, and you may wake up early for the first day or two. Simple things help: get daylight after landing, avoid a long nap, and move your sleep time by about 30 minutes a day before you travel if you want to prepare. If the time zone feels hard to follow, the same tips in our first-time international travel tips guide will help.

Common mistakes to avoid

• Subtracting when you should add. Singapore is ahead of India, so you subtract when you go from Singapore to India.
• Forgetting the half hour. The gap is 2:30, not 2 hours or 3 hours.
• Missing the date change at night. After 9:30 PM in India, it is the next day in Singapore.
• Assuming the gap changes in summer. It does not, for Singapore or India.
• Mixing Singapore with Bangkok or Jakarta. They are one hour behind Singapore.
• Trusting an invite that says only SGT or IST. Add the city name to the invite as well.
