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 +16h Gap: Santiago vs NZDT

Santiago runs on Chile Summer Time (CLST) at UTC-03:00, currently observing daylight saving time. NZDT runs on New Zealand Daylight Time (NZDT) at UTC+13:00. That puts Santiago 16 hours ahead of NZDT — a difference of +16h at the current offsets.

In practice, when it is 9:00 AM in Santiago it is 1:00 AM in NZDT on the next day. Midnight in Santiago is 4:00 PM in NZDT.Santiago observes daylight saving time while NZDT does not, so the gap narrows or widens by an hour part of the year.

Why people convert Santiago to NZDT time

Scheduling a call from Santiago to NZDT: a 10:00 AM start in Santiago lands at 2:00 AM in NZDT the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +16h gap: Santiago and NZDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in NZDT is 1:00 AM in Santiago.
Coordinating a Santiago-based team with NZDT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +16h gap is not.
With a +16h gap there is no shared 9-to-5 window, so alternate the early start: one week Santiago takes the early slot, the next week NZDT does.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the +16h gap.

About CLT (Chile Standard Time)

Chile Standard Time (CLT) is the standard time in Chile. During summer months (October to March), Chile switches to Chile Summer Time (CLST, UTC-03:00). Chile is the longest north-south country in the world.

About NZDT (New Zealand Daylight Time)

New Zealand Daylight Time (NZDT) is the summer time zone for New Zealand, one hour ahead of New Zealand Standard Time (NZST, UTC+12:00).

At UTC+13:00, NZDT is among the earliest offsets in the world — only Samoa, Tonga and parts of Kiribati run further ahead at certain times of year. Auckland and Wellington are 13 hours ahead of UTC during NZDT, 12 hours ahead of Sydney, and 18 hours ahead of New York. The Chatham Islands, 45 minutes further east, move to UTC+13:45.

Best time to call between Santiago and NZDT

With a +16h offset there is no overlap inside a normal 9 AM – 5 PM day. NZDT opens at 9:00 AM NZDT, which is 1:00 AM in Santiago, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Santiago and NZDT have no shared working hours because of the +16h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Santiago is 16 hours ahead of NZDT (CLST UTC-03:00 → NZDT UTC+13:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
