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).

Bangladesh vs NST: Offsets, DST and Best Call Times

Bangladesh runs on Bangladesh Standard Time (BDST) at UTC+06:00. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts Bangladesh 9 hours 30 minutes behind NST — a difference of -9h 30m at the current offsets.

In practice, when it is 9:00 AM in Bangladesh it is 11:30 PM in NST on the previous day. Midnight in Bangladesh is 2:30 PM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Bangladesh to NST time

Scheduling a call from Bangladesh to NST: a 10:00 AM start in Bangladesh lands at 12:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h 30m gap: Bangladesh and NST 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 NST is 11:30 PM in Bangladesh.
Coordinating a Bangladesh-based team with NST 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 BDST" is unambiguous; "3 PM" across a -9h 30m gap is not.
With a -9h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week Bangladesh takes the early slot, the next week NST does.

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.

About NST (Newfoundland Standard Time)

Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.

Best time to call between Bangladesh and NST

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

Business hours overlap

Bangladesh and NST have no shared working hours because of the -9h 30m gap. Teams need to alternate early starts or rely on asynchronous handovers.

Bangladesh is 9 hours 30 minutes behind NST (BDST UTC+06:00 → NST UTC-03:30). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
