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 Osaka to Nepal time

Scheduling a call from Osaka to Nepal: a 10:00 AM start in Osaka lands at 6:45 AM in Nepal, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Osaka and Nepal are inside the 9-to-5 working day between 12:15 PM and 5:00 PM JST time (9:00 AM–1:45 PM NPT). That is roughly 4 hours 45 minutes of usable overlap.
Coordinating a Osaka-based team with Nepal 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 JST" is unambiguous; "3 PM" across a -3h 15m gap is not.
Block 12:15 PM–5:00 PM JST as the recurring meeting window if you work primarily from Osaka and need Nepal colleagues present.

About JST (Japan Standard Time)

Japan Standard Time (JST) is the standard time zone for all of Japan. Japan does not observe daylight saving time. JST is 9 hours ahead of UTC and 14 hours ahead of EST. The Tokyo Stock Exchange, the world's third largest by market capitalization, operates on JST. South Korea uses the same offset (KST) but it is a distinct time zone.

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 Osaka and Nepal

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

Business hours overlap

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

Osaka is 3 hours 15 minutes behind Nepal (JST UTC+09:00 → NPT UTC+05:45). The shared working window is 12:15 PM–5:00 PM JST. Remember to re-check around daylight-saving transitions.
