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 Indonesia to Hong Kong time

Scheduling a call from Indonesia to Hong Kong: a 10:00 AM start in Indonesia lands at 11:00 AM in Hong Kong, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Indonesia and Hong Kong are inside the 9-to-5 working day between 9:00 AM and 4:00 PM WIB time (10:00 AM–5:00 PM HKT). That is roughly 7 hours of usable overlap.
Booking travel or deliveries: tracking Hong Kong local time against Indonesia keeps pickup windows and arrival estimates honest across the +1h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM WIB as the recurring meeting window if you work primarily from Indonesia and need Hong Kong colleagues present.

About WIB (Western Indonesia Time)

Western Indonesia Time (WIB, Waktu Indonesia Barat) is one of Indonesia's three time zones, fixed at UTC+07:00 all year. It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung. Indonesia does not observe daylight saving time, so WIB never shifts. WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

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.

Best time to call between Indonesia and Hong Kong

Both Indonesia and Hong Kong sit inside the 9 AM – 5 PM working day between 9:00 AM–4:00 PM WIB, which is 10:00 AM–5:00 PM HKT. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Indonesia and Hong Kong share 7 hours of working-hours overlap (9:00 AM–4:00 PM WIB), so scheduling a live meeting is straightforward.

Indonesia is 1 hour ahead of Hong Kong (WIB UTC+07:00 → HKT UTC+08:00). The shared working window is 9:00 AM–4:00 PM WIB. Remember to re-check around daylight-saving transitions.
