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 Hong Kong to Cairo time

Scheduling a call from Hong Kong to Cairo: a 10:00 AM start in Hong Kong lands at 5:00 AM in Cairo, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Hong Kong and Cairo are inside the 9-to-5 working day between 2:00 PM and 5:00 PM HKT time (9:00 AM–12:00 PM EEST). That is roughly 3 hours of usable overlap.
Booking travel or deliveries: tracking Cairo local time against Hong Kong keeps pickup windows and arrival estimates honest across the -5h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM HKT" is unambiguous; "3 PM" across a -5h gap is not.
Block 2:00 PM–5:00 PM HKT as the recurring meeting window if you work primarily from Hong Kong and need Cairo colleagues present.
Cairo: Clocks fall back on Thu, Oct 29, 2026. Any meeting series spanning that date will shift by an hour in local time.

About HKT (Hong Kong Time)

Hong Kong Time (HKT) is fixed at UTC+08:00 all year and does not observe daylight saving time. Hong Kong last used summer time in 1979 and has kept a single offset since. HKT shares the UTC+08:00 offset with China Standard Time, Singapore Time, Malaysian Time, Philippine Time and Australian Western Standard Time, but is listed separately because Hong Kong maintains its own timekeeping authority. As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.

About EET (Eastern European Time)

Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.

Best time to call between Hong Kong and Cairo

Both Hong Kong and Cairo sit inside the 9 AM – 5 PM working day between 2:00 PM–5:00 PM HKT, which is 9:00 AM–12:00 PM EEST. That gives roughly 3 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Hong Kong and Cairo overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.

Hong Kong is 5 hours behind Cairo (HKT UTC+08:00 → EEST UTC+03:00). The shared working window is 2:00 PM–5:00 PM HKT. Remember to re-check around daylight-saving transitions.
