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: NST to PET

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

In practice, when it is 9:00 AM in NST it is 7:30 AM in PET. Midnight in NST is 10:30 PM in PET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NST to PET time

Scheduling a call from NST to PET: a 10:00 AM start in NST lands at 8:30 AM in PET, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both NST and PET are inside the 9-to-5 working day between 10:30 AM and 5:00 PM NST time (9:00 AM–3:30 PM PET). That is roughly 6 hours 30 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in NST is 6:30 PM in PET makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM NST" is unambiguous; "3 PM" across a -1h 30m gap is not.
Block 10:30 AM–5:00 PM NST as the recurring meeting window if you work primarily from NST and need PET colleagues present.

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.

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.

Best time to call between NST and PET

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

Business hours overlap

NST and PET share 6 hours of working-hours overlap (10:30 AM–5:00 PM NST), so scheduling a live meeting is straightforward.

NST is 1 hour 30 minutes behind PET (NST UTC-03:30 → PET UTC-05:00). The shared working window is 10:30 AM–5:00 PM NST. Remember to re-check around daylight-saving transitions.
