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).

Nepal vs Sri Lanka: Offsets, DST and Best Call Times

Nepal runs on Nepal Time (NPT) at UTC+05:45. Sri Lanka runs on India Standard Time (IST) at UTC+05:30. That puts Nepal 15 minutes behind Sri Lanka — a difference of -0h 15m at the current offsets.

In practice, when it is 9:00 AM in Nepal it is 8:45 AM in Sri Lanka. Midnight in Nepal is 11:45 PM in Sri Lanka. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Nepal to Sri Lanka time

Scheduling a call from Nepal to Sri Lanka: a 10:00 AM start in Nepal lands at 9:45 AM in Sri Lanka, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Nepal and Sri Lanka are inside the 9-to-5 working day between 9:15 AM and 5:00 PM NPT time (9:00 AM–4:45 PM IST). That is roughly 7 hours 45 minutes of usable overlap.
Watching a live event or market open: Nepal viewers need 8:45 AM in Sri Lanka to catch a 9:00 AM start there, and 12:15 AM if the event is anchored to Nepal.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -0h 15m gap is not.
Block 9:15 AM–5:00 PM NPT as the recurring meeting window if you work primarily from Nepal and need Sri Lanka 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 IST (India Standard Time)

India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.

Best time to call between Nepal and Sri Lanka

Both Nepal and Sri Lanka sit inside the 9 AM – 5 PM working day between 9:15 AM–5:00 PM NPT, which is 9:00 AM–4:45 PM IST. That gives roughly 7 hours and 45 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

Nepal and Sri Lanka share 7 hours of working-hours overlap (9:15 AM–5:00 PM NPT), so scheduling a live meeting is straightforward.

Nepal is 15 minutes behind Sri Lanka (NPT UTC+05:45 → IST UTC+05:30). The shared working window is 9:15 AM–5:00 PM NPT. Remember to re-check around daylight-saving transitions.
