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.

•Singapore does not observe daylight saving time.
•The Singapore Exchange (SGX) operates on SGT.

Understanding the +2h 15m Gap: NPT vs SGT

NPT runs on Nepal Time (NPT) at UTC+05:45. SGT runs on Singapore Standard Time (SGT) at UTC+08:00. That puts NPT 2 hours 15 minutes ahead of SGT — a difference of +2h 15m at the current offsets.

In practice, when it is 9:00 AM in NPT it is 11:15 AM in SGT. Midnight in NPT is 2:15 AM in SGT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NPT to SGT time

Scheduling a call from NPT to SGT: a 10:00 AM start in NPT lands at 12:15 PM in SGT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both NPT and SGT are inside the 9-to-5 working day between 9:00 AM and 2:45 PM NPT time (11:15 AM–5:00 PM SGT). That is roughly 5 hours 45 minutes of usable overlap.
Coordinating a NPT-based team with SGT 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 +2h 15m gap is not.
Block 9:00 AM–2:45 PM NPT as the recurring meeting window if you work primarily from NPT and need SGT 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 SGT (Singapore Standard Time)

Singapore Standard Time (SGT) is used in Singapore year-round. Singapore does not observe daylight saving time. Despite being geographically close to the UTC+07:00 zone, Singapore uses UTC+08:00 to align with major trading partners like China, Hong Kong, and Malaysia. Singapore is a major global financial hub.

Best time to call between NPT and SGT

Both NPT and SGT sit inside the 9 AM – 5 PM working day between 9:00 AM–2:45 PM NPT, which is 11:15 AM–5:00 PM SGT. That gives roughly 5 hours and 45 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

NPT and SGT share 5 hours of working-hours overlap (9:00 AM–2:45 PM NPT), so scheduling a live meeting is straightforward.

NPT is 2 hours 15 minutes ahead of SGT (NPT UTC+05:45 → SGT UTC+08:00). The shared working window is 9:00 AM–2:45 PM NPT. Remember to re-check around daylight-saving transitions.
