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).

AKST vs BST: Offsets, DST and Best Call Times

AKST runs on Alaska Standard Time (AKST) at UTC-09:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts AKST 10 hours ahead of BST — a difference of +10h at the current offsets.

In practice, when it is 9:00 AM in AKST it is 7:00 PM in BST. Midnight in AKST is 10:00 AM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AKST to BST time

Scheduling a call from AKST to BST: a 10:00 AM start in AKST lands at 8:00 PM in BST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h gap: AKST and BST 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 BST is 7:00 PM in AKST.
Keeping family and friends in sync: knowing that 8:00 PM in AKST is 6:00 AM in BST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM AKST" 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 AKST takes the early slot, the next week BST does.

About AKST (Alaska Standard Time)

Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).

About BST (British Summer Time)

British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.

Best time to call between AKST and BST

With a +10h offset there is no overlap inside a normal 9 AM – 5 PM day. BST opens at 9:00 AM BST, which is 7:00 PM in AKST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

AKST and BST have no shared working hours because of the +10h gap. Teams need to alternate early starts or rely on asynchronous handovers.

AKST is 10 hours ahead of BST (AKST UTC-09:00 → BST UTC+01:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
