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).

Beijing vs Indonesia: Offsets, DST and Best Call Times

Beijing runs on China Standard Time (CST) at UTC+08:00. Indonesia runs on Western Indonesia Time (WIB) at UTC+07:00. That puts Beijing 1 hour behind Indonesia — a difference of -1h at the current offsets.

In practice, when it is 9:00 AM in Beijing it is 8:00 AM in Indonesia. Midnight in Beijing is 11:00 PM in Indonesia. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Beijing to Indonesia time

Scheduling a call from Beijing to Indonesia: a 10:00 AM start in Beijing lands at 9:00 AM in Indonesia, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Beijing and Indonesia are inside the 9-to-5 working day between 10:00 AM and 5:00 PM CST time (9:00 AM–4:00 PM WIB). That is roughly 7 hours of usable overlap.
Watching a live event or market open: Beijing viewers need 8:00 AM in Indonesia to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to Beijing.

Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a -1h gap is not.
Block 10:00 AM–5:00 PM CST as the recurring meeting window if you work primarily from Beijing and need Indonesia colleagues present.

About CST (China Standard Time)

China Standard Time (CST, also known as Beijing Time) is used across all of mainland China despite the country spanning five geographical time zones. This single-timezone policy was adopted in 1949. China does not observe daylight saving time. CST is shared with Hong Kong (HKT), Macau, Taiwan, Singapore, Malaysia, and the Philippines, making UTC+08:00 one of the most used offsets in the world.

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.

Best time to call between Beijing and Indonesia

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

Business hours overlap

Beijing and Indonesia share 7 hours of working-hours overlap (10:00 AM–5:00 PM CST), so scheduling a live meeting is straightforward.

Beijing is 1 hour behind Indonesia (CST UTC+08:00 → WIB UTC+07:00). The shared working window is 10:00 AM–5:00 PM CST. Remember to re-check around daylight-saving transitions.
