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).

Key Facts about GMT

•GMT is based on the Prime Meridian (0° longitude) passing through Greenwich, London.
•The Royal Observatory in Greenwich has been the reference point for GMT since 1884.
•GMT and UTC are often used interchangeably, but UTC is based on atomic clocks.
•Iceland uses GMT year-round and never observes daylight saving time.
•The UK switches from GMT to BST (British Summer Time) in late March each year.

Daylight Saving:Yes – switches to BST

Understanding the +1h Gap: Dublin vs EET

Dublin runs on Irish Standard Time (IST) at UTC+01:00, currently observing daylight saving time. EET runs on Eastern European Time (EET) at UTC+02:00. That puts Dublin 1 hour ahead of EET — a difference of +1h at the current offsets.

In practice, when it is 9:00 AM in Dublin it is 10:00 AM in EET. Midnight in Dublin is 1:00 AM in EET.Dublin observes daylight saving time while EET does not, so the gap narrows or widens by an hour part of the year.

Why people convert Dublin to EET time

Scheduling a call from Dublin to EET: a 10:00 AM start in Dublin lands at 11:00 AM in EET, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Dublin and EET are inside the 9-to-5 working day between 9:00 AM and 4:00 PM IST time (10:00 AM–5:00 PM EET). That is roughly 7 hours of usable overlap.
Booking travel or deliveries: tracking EET local time against Dublin keeps pickup windows and arrival estimates honest across the +1h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM IST as the recurring meeting window if you work primarily from Dublin and need EET colleagues present.
Dublin: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +1h 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 EET (Eastern European Time)

Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.

Best time to call between Dublin and EET

Both Dublin and EET sit inside the 9 AM – 5 PM working day between 9:00 AM–4:00 PM IST, which is 10:00 AM–5:00 PM EET. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Dublin and EET share 7 hours of working-hours overlap (9:00 AM–4:00 PM IST), so scheduling a live meeting is straightforward.

Dublin is 1 hour ahead of EET (IST UTC+01:00 → EET UTC+02:00). The shared working window is 9:00 AM–4:00 PM IST. Remember to re-check around daylight-saving transitions.
