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).

NPT – Nepal Time

UTC+05:45

Nepal Time (NPT, UTC+05:45) is the time zone for Nepal — one of the few offsets in the world set on a 45-minute increment.

Key Facts about NPT

•Nepal Time is UTC+05:45 — a 45-minute offset, not a whole or half hour.
•The 45-minute offset was adopted in 1986 to match Kathmandu's solar time.
•Nepal does not observe daylight saving time.
•Nepal is 15 minutes ahead of India, despite sharing a long open border.

Daylight Saving:No – UTC+05:45 year-round

South Africa Standard Time (SAST) is the time zone for South Africa and neighboring countries, 2 hours ahead of UTC.

Comparing Time Zones: NPT and SAST

NPT runs on Nepal Time (NPT) at UTC+05:45. SAST runs on South Africa Standard Time (SAST) at UTC+02:00. That puts NPT 3 hours 45 minutes behind SAST — a difference of -3h 45m at the current offsets.

In practice, when it is 9:00 AM in NPT it is 5:15 AM in SAST. Midnight in NPT is 8:15 PM in SAST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NPT to SAST time

Scheduling a call from NPT to SAST: a 10:00 AM start in NPT lands at 6:15 AM in SAST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both NPT and SAST are inside the 9-to-5 working day between 12:45 PM and 5:00 PM NPT time (9:00 AM–1:15 PM SAST). That is roughly 4 hours 15 minutes of usable overlap.
Coordinating a NPT-based team with SAST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -3h 45m gap is not.
Block 12:45 PM–5:00 PM NPT as the recurring meeting window if you work primarily from NPT and need SAST colleagues present.

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 SAST (South Africa Standard Time)

South Africa Standard Time (SAST) is used in South Africa, Lesotho, and Eswatini. SAST does not observe daylight saving time. Johannesburg and Cape Town are major economic hubs in Africa.

Best time to call between NPT and SAST

Both NPT and SAST sit inside the 9 AM – 5 PM working day between 12:45 PM–5:00 PM NPT, which is 9:00 AM–1:15 PM SAST. That gives roughly 4 hours and 15 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

NPT and SAST overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.

NPT is 3 hours 45 minutes behind SAST (NPT UTC+05:45 → SAST UTC+02:00). The shared working window is 12:45 PM–5:00 PM NPT. Remember to re-check around daylight-saving transitions.
