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 -10h Gap: NZST vs Vienna

NZST runs on New Zealand Standard Time (NZST) at UTC+12:00. Vienna runs on Central European Summer Time (CEST) at UTC+02:00, also currently on daylight saving time. That puts NZST 10 hours behind Vienna — a difference of -10h at the current offsets.

In practice, when it is 9:00 AM in NZST it is 11:00 PM in Vienna on the previous day. Midnight in NZST is 2:00 PM in Vienna.Vienna observes daylight saving time while NZST does not, so the gap narrows or widens by an hour part of the year.

Why people convert NZST to Vienna time

Scheduling a call from NZST to Vienna: a 10:00 AM start in NZST lands at 12:00 AM in Vienna, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h gap: NZST and Vienna 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 Vienna is 11:00 PM in NZST.
Watching a live event or market open: NZST viewers need 11:00 PM in Vienna to catch a 9:00 AM start there, and 10:00 AM if the event is anchored to NZST.

Always state the zone abbreviation, not just the hour. "3:00 PM NZST" is unambiguous; "3 PM" across a -10h gap is not.
With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week NZST takes the early slot, the next week Vienna does.
Vienna: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
