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 Argentina to Dhaka time

Scheduling a call from Argentina to Dhaka: a 10:00 AM start in Argentina lands at 7:00 PM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
Handling a +9h gap: Argentina and Dhaka 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 Dhaka is 6:00 PM in Argentina.
Coordinating a Argentina-based team with Dhaka 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 ART" is unambiguous; "3 PM" across a +9h gap is not.
With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week Argentina takes the early slot, the next week Dhaka does.

About ART (Argentina Time)

Argentina Time (ART) is the time zone used throughout Argentina. Argentina does not observe daylight saving time. ART shares the same offset as Brasilia Time (BRT) and Uruguay's UYT.

About BDST (Bangladesh Standard Time)

Bangladesh Standard Time (BDST) is the single time zone used across Bangladesh, fixed at UTC+06:00 all year. Bangladesh has not observed daylight saving time since a short-lived experiment in 2009, so the gap between Bangladesh and every other zone is constant. Dhaka, the capital, is one of the most densely populated cities in the world. Because the country sits close to the middle of the UTC+06:00 band, solar noon is near 12:00 for most of the year. BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.

Best time to call between Argentina and Dhaka

With a +9h offset there is no overlap inside a normal 9 AM – 5 PM day. Dhaka opens at 9:00 AM BDST, which is 6:00 PM in Argentina, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Argentina and Dhaka have no shared working hours because of the +9h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Argentina is 9 hours ahead of Dhaka (ART UTC-03:00 → BDST 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.
