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).

Everything You Need to Know About Indonesia and Kathmandu Time

Indonesia runs on Western Indonesia Time (WIB) at UTC+07:00. Kathmandu runs on Nepal Time (NPT) at UTC+05:45. That puts Indonesia 1 hour 15 minutes behind Kathmandu — a difference of -1h 15m at the current offsets.

In practice, when it is 9:00 AM in Indonesia it is 7:45 AM in Kathmandu. Midnight in Indonesia is 10:45 PM in Kathmandu. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Indonesia to Kathmandu time

Scheduling a call from Indonesia to Kathmandu: a 10:00 AM start in Indonesia lands at 8:45 AM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Indonesia and Kathmandu are inside the 9-to-5 working day between 10:15 AM and 5:00 PM WIB time (9:00 AM–3:45 PM NPT). That is roughly 6 hours 45 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Indonesia is 6:45 PM in Kathmandu makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a -1h 15m gap is not.
Block 10:15 AM–5:00 PM WIB as the recurring meeting window if you work primarily from Indonesia and need Kathmandu 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 NPT (Nepal Time)

Nepal Time (NPT) runs at UTC+05:45, one of only a handful of time zones worldwide that are not a whole or half hour from UTC. Nepal set its offset to 5 hours 45 minutes ahead of UTC in 1986 to mark the country's position between the 75°E and 90°E meridians; Kathmandu's solar time sits just over 5 hours 41 minutes ahead of Greenwich, so the 45-minute offset tracks the sun more closely than either 5:30 or 6:00 would. Nepal does not observe daylight saving time, so NPT is fixed all year. The offset makes Nepal 15 minutes ahead of India Standard Time (UTC+05:30) and 2 hours 15 minutes ahead of Dubai (UTC+04:00).

Best time to call between Indonesia and Kathmandu

Both Indonesia and Kathmandu sit inside the 9 AM – 5 PM working day between 10:15 AM–5:00 PM WIB, which is 9:00 AM–3:45 PM NPT. That gives roughly 6 hours and 45 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

Indonesia and Kathmandu share 6 hours of working-hours overlap (10:15 AM–5:00 PM WIB), so scheduling a live meeting is straightforward.

Indonesia is 1 hour 15 minutes behind Kathmandu (WIB UTC+07:00 → NPT UTC+05:45). The shared working window is 10:15 AM–5:00 PM WIB. Remember to re-check around daylight-saving transitions.
