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 Accra to Perth time

Scheduling a call from Accra to Perth: a 10:00 AM start in Accra lands at 6:00 PM in Perth, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h gap: Accra and Perth 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 Perth is 5:00 PM in Accra.
Watching a live event or market open: Accra viewers need 5:00 PM in Perth to catch a 9:00 AM start there, and 4:00 PM if the event is anchored to Accra.

Always state the zone abbreviation, not just the hour. "3:00 PM GMT" is unambiguous; "3 PM" across a +8h gap is not.
With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week Accra takes the early slot, the next week Perth does.

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 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 Accra and Perth

With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. Perth opens at 9:00 AM AWST, which is 5:00 PM in Accra, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Accra and Perth have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Accra is 8 hours ahead of Perth (GMT UTC+00:00 → AWST 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.
