Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Understanding the +8h 30m Gap: Chile vs Mumbai

Chile runs on Chile Summer Time (CLST) at UTC-03:00, currently observing daylight saving time. Mumbai runs on India Standard Time (IST) at UTC+05:30. That puts Chile 8 hours 30 minutes ahead of Mumbai — a difference of +8h 30m at the current offsets.

In practice, when it is 9:00 AM in Chile it is 5:30 PM in Mumbai. Midnight in Chile is 8:30 AM in Mumbai.Chile observes daylight saving time while Mumbai does not, so the gap narrows or widens by an hour part of the year.

Why people convert Chile to Mumbai time

Scheduling a call from Chile to Mumbai: a 10:00 AM start in Chile lands at 6:30 PM in Mumbai, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h 30m gap: Chile and Mumbai have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Mumbai is 5:30 PM in Chile.
Booking travel or deliveries: tracking Mumbai local time against Chile keeps pickup windows and arrival estimates honest across the +8h 30m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +8h 30m gap is not.
With a +8h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week Chile takes the early slot, the next week Mumbai does.
