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).

Time Conversion Guide: Ireland to AKST

Ireland runs on Irish Standard Time (IST) at UTC+01:00, currently observing daylight saving time. AKST runs on Alaska Standard Time (AKST) at UTC-09:00. That puts Ireland 10 hours behind AKST — a difference of -10h at the current offsets.

In practice, when it is 9:00 AM in Ireland it is 11:00 PM in AKST on the previous day. Midnight in Ireland is 2:00 PM in AKST.Ireland observes daylight saving time while AKST does not, so the gap narrows or widens by an hour part of the year.

Why people convert Ireland to AKST time

Scheduling a call from Ireland to AKST: a 10:00 AM start in Ireland lands at 12:00 AM in AKST, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h gap: Ireland and AKST 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 AKST is 11:00 PM in Ireland.
Coordinating a Ireland-based team with AKST 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 IST" 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 Ireland takes the early slot, the next week AKST does.
Ireland: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -10h gap.

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 Ireland and AKST

With a -10h offset there is no overlap inside a normal 9 AM – 5 PM day. AKST opens at 9:00 AM AKST, which is 11:00 PM in Ireland, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

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

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