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 SAST and NPT Time

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

In practice, when it is 9:00 AM in SAST it is 12:45 PM in NPT. Midnight in SAST is 3:45 AM in NPT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert SAST to NPT time

Scheduling a call from SAST to NPT: a 10:00 AM start in SAST lands at 1:45 PM in NPT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both SAST and NPT are inside the 9-to-5 working day between 9:00 AM and 1:15 PM SAST time (12:45 PM–5:00 PM NPT). That is roughly 4 hours 15 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in SAST is 11:45 PM in NPT makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM SAST" is unambiguous; "3 PM" across a +3h 45m gap is not.
Block 9:00 AM–1:15 PM SAST as the recurring meeting window if you work primarily from SAST and need NPT colleagues present.

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.

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 SAST and NPT

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

Business hours overlap

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

SAST is 3 hours 45 minutes ahead of NPT (SAST UTC+02:00 → NPT UTC+05:45). The shared working window is 9:00 AM–1:15 PM SAST. Remember to re-check around daylight-saving transitions.
