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).

BST vs AWST: Offsets, DST and Best Call Times

BST runs on British Summer Time (BST) at UTC+01:00. AWST runs on Australian Western Standard Time (AWST) at UTC+08:00. That puts BST 7 hours ahead of AWST — a difference of +7h at the current offsets.

In practice, when it is 9:00 AM in BST it is 4:00 PM in AWST. Midnight in BST is 7:00 AM in AWST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert BST to AWST time

Scheduling a call from BST to AWST: a 10:00 AM start in BST lands at 5:00 PM in AWST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both BST and AWST are inside the 9-to-5 working day between 9:00 AM and 10:00 AM BST time (4:00 PM–5:00 PM AWST). That is roughly 1 hours of usable overlap.
Booking travel or deliveries: tracking AWST local time against BST keeps pickup windows and arrival estimates honest across the +7h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +7h gap is not.
Block 9:00 AM–10:00 AM BST as the recurring meeting window if you work primarily from BST and need AWST colleagues present.

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.

About AWST (Australian Western Standard Time)

Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.

Best time to call between BST and AWST

Both BST and AWST sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM BST, which is 4:00 PM–5:00 PM AWST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

BST and AWST overlap for only 60 minutes (9:00 AM–10:00 AM BST), so meetings have to be booked precisely.

BST is 7 hours ahead of AWST (BST UTC+01:00 → AWST UTC+08:00). The shared working window is 9:00 AM–10:00 AM BST. Remember to re-check around daylight-saving transitions.
