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).

Understanding the -1h Gap: EDT vs PET

EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. PET runs on Peru Time (PET) at UTC-05:00. That puts EDT 1 hour behind PET — a difference of -1h at the current offsets.

In practice, when it is 9:00 AM in EDT it is 8:00 AM in PET. Midnight in EDT is 11:00 PM in PET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EDT to PET time

Scheduling a call from EDT to PET: a 10:00 AM start in EDT lands at 9:00 AM in PET, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both EDT and PET are inside the 9-to-5 working day between 10:00 AM and 5:00 PM EDT time (9:00 AM–4:00 PM PET). That is roughly 7 hours of usable overlap.
Watching a live event or market open: EDT viewers need 8:00 AM in PET to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to EDT.

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

About EDT (Eastern Daylight Time)

Eastern Daylight Time (EDT) is used during the summer months (second Sunday of March to the first Sunday of November) in the Eastern Time Zone. During EDT, clocks are advanced by one hour to take advantage of longer daylight hours. Not all locations in the Eastern Time Zone observe DST – Panama, Jamaica, and most of the Caribbean remain on EST year-round.

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 EDT and PET

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

Business hours overlap

EDT and PET share 7 hours of working-hours overlap (10:00 AM–5:00 PM EDT), so scheduling a live meeting is straightforward.

EDT is 1 hour behind PET (EDT UTC-04:00 → PET UTC-05:00). The shared working window is 10:00 AM–5:00 PM EDT. Remember to re-check around daylight-saving transitions.
