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).

Understanding the +4h 15m Gap: Nepal vs Sydney

Nepal runs on Nepal Time (NPT) at UTC+05:45. Sydney runs on Australian Eastern Standard Time (AEST) at UTC+10:00. That puts Nepal 4 hours 15 minutes ahead of Sydney — a difference of +4h 15m at the current offsets.

In practice, when it is 9:00 AM in Nepal it is 1:15 PM in Sydney. Midnight in Nepal is 4:15 AM in Sydney. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Nepal to Sydney time

Scheduling a call from Nepal to Sydney: a 10:00 AM start in Nepal lands at 2:15 PM in Sydney, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Nepal and Sydney are inside the 9-to-5 working day between 9:00 AM and 12:45 PM NPT time (1:15 PM–5:00 PM AEST). That is roughly 3 hours 45 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Nepal is 12:15 AM in Sydney makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a +4h 15m gap is not.
Block 9:00 AM–12:45 PM NPT as the recurring meeting window if you work primarily from Nepal and need Sydney colleagues present.
Sydney: Clocks spring forward on Sat, Oct 3, 2026. Any meeting series spanning that date will shift by an hour in local time.

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).

About AEST (Australian Eastern Standard Time)

Australian Eastern Standard Time (AEST) is used in the eastern states of Australia including New South Wales, Victoria, Queensland, Tasmania, and the ACT. During summer (October to April), NSW, VIC, TAS, and ACT switch to Australian Eastern Daylight Time (AEDT, UTC+11:00), while Queensland remains on AEST year-round.

Best time to call between Nepal and Sydney

Both Nepal and Sydney sit inside the 9 AM – 5 PM working day between 9:00 AM–12:45 PM NPT, which is 1:15 PM–5:00 PM AEST. That gives roughly 3 hours and 45 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

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

Nepal is 4 hours 15 minutes ahead of Sydney (NPT UTC+05:45 → AEST UTC+10:00). The shared working window is 9:00 AM–12:45 PM NPT. Remember to re-check around daylight-saving transitions.
