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 Pakistan to Ireland time

Scheduling a call from Pakistan to Ireland: a 10:00 AM start in Pakistan lands at 6:00 AM in Ireland, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Pakistan and Ireland are inside the 9-to-5 working day between 1:00 PM and 5:00 PM PKT time (9:00 AM–1:00 PM IST). That is roughly 4 hours of usable overlap.
Watching a live event or market open: Pakistan viewers need 5:00 AM in Ireland to catch a 9:00 AM start there, and 4:00 AM if the event is anchored to Pakistan.

Always state the zone abbreviation, not just the hour. "3:00 PM PKT" is unambiguous; "3 PM" across a -4h gap is not.
Block 1:00 PM–5:00 PM PKT as the recurring meeting window if you work primarily from Pakistan and need Ireland colleagues present.
Ireland: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.

About PKT (Pakistan Standard Time)

Pakistan Standard Time (PKT) is the time zone used throughout Pakistan. PKT does not observe daylight saving time. Pakistan is the 5th most populous country in the world.

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.

Best time to call between Pakistan and Ireland

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

Business hours overlap

Pakistan and Ireland overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.

Pakistan is 4 hours behind Ireland (PKT UTC+05:00 → IST UTC+01:00). The shared working window is 1:00 PM–5:00 PM PKT. Remember to re-check around daylight-saving transitions.
