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).

Why people convert Kathmandu to Nigeria time

Scheduling a call from Kathmandu to Nigeria: a 10:00 AM start in Kathmandu lands at 5:15 AM in Nigeria, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Kathmandu and Nigeria are inside the 9-to-5 working day between 1:45 PM and 5:00 PM NPT time (9:00 AM–12:15 PM WAT). That is roughly 3 hours 15 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Kathmandu is 3:15 PM in Nigeria 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 45m gap is not.
Block 1:45 PM–5:00 PM NPT as the recurring meeting window if you work primarily from Kathmandu and need Nigeria 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 WAT (West Africa Time)

West Africa Time (WAT) is used across much of West and Central Africa, including Nigeria, the most populous country in Africa. WAT does not observe daylight saving time and shares the same offset as Central European Time (CET).

Best time to call between Kathmandu and Nigeria

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

Business hours overlap

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

Kathmandu is 4 hours 45 minutes behind Nigeria (NPT UTC+05:45 → WAT UTC+01:00). The shared working window is 1:45 PM–5:00 PM NPT. Remember to re-check around daylight-saving transitions.
