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).

United Kingdom vs Anchorage: Offsets, DST and Best Call Times

United Kingdom runs on British Summer Time (BST) at UTC+01:00, currently observing daylight saving time. Anchorage runs on Alaska Daylight Time (AKDT) at UTC-08:00, also currently on daylight saving time. That puts United Kingdom 9 hours behind Anchorage — a difference of -9h at the current offsets.

In practice, when it is 9:00 AM in United Kingdom it is 12:00 AM in Anchorage. Midnight in United Kingdom is 3:00 PM in Anchorage. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert United Kingdom to Anchorage time

Scheduling a call from United Kingdom to Anchorage: a 10:00 AM start in United Kingdom lands at 1:00 AM in Anchorage, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h gap: United Kingdom and Anchorage 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 Anchorage is 12:00 AM in United Kingdom.
Booking travel or deliveries: tracking Anchorage local time against United Kingdom keeps pickup windows and arrival estimates honest across the -9h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BST" 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 United Kingdom takes the early slot, the next week Anchorage does.
United Kingdom: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -9h gap.
Anchorage: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.

About GMT (Greenwich Mean Time)

Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

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).

Best time to call between United Kingdom and Anchorage

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

Business hours overlap

United Kingdom and Anchorage have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.

United Kingdom is 9 hours behind Anchorage (BST UTC+01:00 → AKDT UTC-08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
