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).

Comparing Time Zones: Vienna and Cairo

Vienna runs on Central European Summer Time (CEST) at UTC+02:00, currently observing daylight saving time. Cairo runs on Eastern European Summer Time (EEST) at UTC+03:00, also currently on daylight saving time. That puts Vienna 1 hour ahead of Cairo — a difference of +1h at the current offsets.

In practice, when it is 9:00 AM in Vienna it is 10:00 AM in Cairo. Midnight in Vienna is 1:00 AM in Cairo. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert Vienna to Cairo time

Scheduling a call from Vienna to Cairo: a 10:00 AM start in Vienna lands at 11:00 AM in Cairo, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Vienna and Cairo are inside the 9-to-5 working day between 9:00 AM and 4:00 PM CEST time (10:00 AM–5:00 PM EEST). That is roughly 7 hours of usable overlap.
Coordinating a Vienna-based team with Cairo 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 CEST" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM CEST as the recurring meeting window if you work primarily from Vienna and need Cairo colleagues present.
Vienna: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +1h gap.
Cairo: Clocks fall back on Thu, Oct 29, 2026. Any meeting series spanning that date will shift by an hour in local time.
