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).

Why people convert Vienna to PST time

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

Always state the zone abbreviation, not just the hour. "3:00 PM CEST" 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 Vienna takes the early slot, the next week PST does.
Vienna: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -10h gap.

PST is also observed in Baja California, Mexico.
