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).

Time Conversion Guide: India to Mexico

India runs on India Standard Time (IST) at UTC+05:30. Mexico runs on Central Standard Time (CST) at UTC-06:00. That puts India 11 hours 30 minutes behind Mexico — a difference of -11h 30m at the current offsets.

In practice, when it is 9:00 AM in India it is 9:30 PM in Mexico on the previous day. Midnight in India is 12:30 PM in Mexico. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert India to Mexico time

Scheduling a call from India to Mexico: a 10:00 AM start in India lands at 10:30 PM in Mexico the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h 30m gap: India and Mexico 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 Mexico is 9:30 PM in India.
Booking travel or deliveries: tracking Mexico local time against India keeps pickup windows and arrival estimates honest across the -11h 30m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a -11h 30m gap is not.
With a -11h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week India takes the early slot, the next week Mexico does.

About IST (India Standard Time)

India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.

About CST (Central Standard Time)

Central Standard Time (CST) covers the central region of North America. It is the second most populous time zone in the US, including major cities like Chicago, Houston, and Dallas. CST is also used in Mexico City and much of Central America including Guatemala, Honduras, El Salvador, and Costa Rica. During summer, most of the US and Canada switch to Central Daylight Time (CDT, UTC-05:00), while Mexico and Central American countries generally remain on CST.

Best time to call between India and Mexico

With a -11h 30m offset there is no overlap inside a normal 9 AM – 5 PM day. Mexico opens at 9:00 AM CST, which is 9:30 PM in India, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

India and Mexico have no shared working hours because of the -11h 30m gap. Teams need to alternate early starts or rely on asynchronous handovers.

India is 11 hours 30 minutes behind Mexico (IST UTC+05:30 → CST UTC-06:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
