Mumbai Time Now

What this page shows

So you want to know what time it is in Mumbai right now. Maybe you have a call with someone in India, a flight to catch, a market open to track, or someone to reach before their evening is over. That is what the clock at the top of this page is for. It shows the current time in Mumbai and ticks forward every second, so there is nothing for you to work out by hand.

Wherever in the world you are reading this from, the clock tracks Mumbai and keeps itself right on its own. And Mumbai time is simple, because it never changes through the year, as the next section explains.

Mumbai does not change its clocks

Here is the part worth knowing about Mumbai time, and it makes things easy. India does not use daylight saving. There is no spring forward and no fall back, so Mumbai stays on the same clock all year round, India Standard Time, five and a half hours ahead of UTC.

So there are no change dates to track here. Whenever you look, Mumbai is at UTC plus 5:30, and the clock above simply shows that time. The half-hour offset is the part that catches people out, since most of the world runs on whole hours, but it never shifts with the seasons.

What time zone Mumbai is in

Mumbai runs on India Standard Time, five and a half hours ahead of UTC, held every day of the year. It keeps the same clock as the rest of India, since the whole country runs on this single zone.

For a city that is India's financial heart, the steady clock matters. Mumbai is home to the Bombay Stock Exchange, the oldest in Asia, and the National Stock Exchange, so India's market hours are set and quoted in India Standard Time from here. The city also sits on the west coast, at the western edge of the country's single time zone, which means that of all the big Indian cities, Mumbai is where the sun runs furthest behind the clock, a point the facts section picks up.

Time difference from Mumbai to other cities

Mumbai never changes its clocks, so the gap to other fixed-offset places stays the same all year. The places that do use daylight saving, like London and New York, shift by an hour against Mumbai between their winter and summer. Here is the quick reference, assuming it is 12 noon in Mumbai.

A few quick examples

Let us run a few, so you can see how this works.

Say it is 12 noon in Mumbai. Kathmandu is fifteen minutes ahead at 12:15, and Singapore is two and a half hours ahead at 2:30 in the afternoon. Dubai, a short hop across the Arabian Sea, is an hour and a half behind at 10:30 in the morning.

Now the long hauls west. In the winter, London is five and a half hours behind Mumbai, so 12 noon here is half past six in the morning in London, and New York, ten and a half hours behind, is at half past one in the morning. The half-hour offset is why these land on a thirty rather than on the hour.

Because those places use daylight saving and India does not, the gap shifts by an hour in their summer. London moves to four and a half hours behind and New York to nine and a half. So for a call that has to land just right, check the live clock rather than the rule of thumb.

A couple of things about Mumbai time

Mumbai sits at about 19 degrees north, well to the south, so the length of the day stays fairly even through the year. Around midsummer there are roughly thirteen hours between sunrise and sunset, and around midwinter still about eleven, a gentler swing than the cities of the north.

On the clock-against-sun question, Mumbai runs the furthest behind the sun of any major Indian city. India Standard Time is built on a meridian near the centre of the country, and Mumbai sits well to the west of it, on the coast, so the sun reaches its highest a good while after 12 noon by the clock, at around 12:40 in the middle of the year. It is the reason Mumbai sunsets feel a touch late, and a steady effect, since the clock never shifts.

Other places on the same time

The whole of India keeps the same time as Mumbai on UTC plus 5:30. Here are some to jump to:

• New Delhi time now, on the same clock
• Bangalore time now, on the same clock
• India time now, the country as a whole

No. India does not use daylight saving anywhere, so Mumbai keeps India Standard Time, UTC plus 5:30, all year with no seasonal change.

Yes, exactly. The whole of India keeps a single zone, so Mumbai and Delhi always read the same clock, even though Mumbai is further south and west.

What time zone is Mumbai in?

India Standard Time, five and a half hours ahead of UTC, held all year. It is the single clock used across the whole of India.

What is the time difference between Mumbai and New York?
