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).

Why people convert Colombia to Thailand time

Scheduling a call from Colombia to Thailand: a 10:00 AM start in Colombia lands at 10:00 PM in Thailand, so you can confirm the slot without doing the arithmetic yourself.
Handling a +12h gap: Colombia and Thailand 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 Thailand is 9:00 PM in Colombia.
Keeping family and friends in sync: knowing that 8:00 PM in Colombia is 8:00 AM in Thailand makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +12h gap is not.
With a +12h gap there is no shared 9-to-5 window, so alternate the early start: one week Colombia takes the early slot, the next week Thailand does.

About COT (Colombia Time)

Colombia Time (COT) is used throughout Colombia. Colombia does not observe daylight saving time. COT shares the same offset as EST (UTC-05:00). Bogotá, the capital, is one of the largest cities in South America.

About ICT (Indochina Time)

Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.

Best time to call between Colombia and Thailand

With a +12h offset there is no overlap inside a normal 9 AM – 5 PM day. Thailand opens at 9:00 AM ICT, which is 9:00 PM in Colombia, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Colombia and Thailand have no shared working hours because of the +12h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Colombia is 12 hours ahead of Thailand (COT UTC-05:00 → ICT UTC+07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
