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: PET to NST

PET runs on Peru Time (PET) at UTC-05:00. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts PET 1 hour 30 minutes ahead of NST — a difference of +1h 30m at the current offsets.

In practice, when it is 9:00 AM in PET it is 10:30 AM in NST. Midnight in PET is 1:30 AM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert PET to NST time

Scheduling a call from PET to NST: a 10:00 AM start in PET lands at 11:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both PET and NST are inside the 9-to-5 working day between 9:00 AM and 3:30 PM PET time (10:30 AM–5:00 PM NST). That is roughly 6 hours 30 minutes of usable overlap.
Watching a live event or market open: PET viewers need 10:30 AM in NST to catch a 9:00 AM start there, and 10:30 PM if the event is anchored to PET.

Always state the zone abbreviation, not just the hour. "3:00 PM PET" is unambiguous; "3 PM" across a +1h 30m gap is not.
Block 9:00 AM–3:30 PM PET as the recurring meeting window if you work primarily from PET and need NST colleagues present.

About PET (Peru Time)

Peru Time (PET) is the time zone used throughout Peru. Peru does not observe daylight saving time. PET shares the same offset as EST (UTC-05:00). Lima, the capital, is the economic center of Peru.

About NST (Newfoundland Standard Time)

Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.

Best time to call between PET and NST

Both PET and NST sit inside the 9 AM – 5 PM working day between 9:00 AM–3:30 PM PET, which is 10:30 AM–5:00 PM NST. That gives roughly 6 hours and 30 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

PET and NST share 6 hours of working-hours overlap (9:00 AM–3:30 PM PET), so scheduling a live meeting is straightforward.

PET is 1 hour 30 minutes ahead of NST (PET UTC-05:00 → NST UTC-03:30). The shared working window is 9:00 AM–3:30 PM PET. Remember to re-check around daylight-saving transitions.
