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 -10h Gap: Thailand vs Argentina

Thailand runs on Indochina Time (ICT) at UTC+07:00. Argentina runs on Argentina Standard Time (ART) at UTC-03:00. That puts Thailand 10 hours behind Argentina — a difference of -10h at the current offsets.

In practice, when it is 9:00 AM in Thailand it is 11:00 PM in Argentina on the previous day. Midnight in Thailand is 2:00 PM in Argentina. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Thailand to Argentina time

Scheduling a call from Thailand to Argentina: a 10:00 AM start in Thailand lands at 12:00 AM in Argentina, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h gap: Thailand and Argentina 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 Argentina is 11:00 PM in Thailand.
Coordinating a Thailand-based team with Argentina contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -10h gap is not.
With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week Thailand takes the early slot, the next week Argentina does.

Business hours overlap

Thailand is 10 hours behind Argentina (ICT UTC+07:00 → ART UTC-03:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
