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 BDST to Kathmandu time

Scheduling a call from BDST to Kathmandu: a 10:00 AM start in BDST lands at 9:45 AM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both BDST and Kathmandu are inside the 9-to-5 working day between 9:15 AM and 5:00 PM BDST time (9:00 AM–4:45 PM NPT). That is roughly 7 hours 45 minutes of usable overlap.
Coordinating a BDST-based team with Kathmandu 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 BDST" is unambiguous; "3 PM" across a -0h 15m gap is not.
Block 9:15 AM–5:00 PM BDST as the recurring meeting window if you work primarily from BDST and need Kathmandu colleagues present.

About BDST (Bangladesh Standard Time)

Bangladesh Standard Time (BDST) is the single time zone used across Bangladesh, fixed at UTC+06:00 all year. Bangladesh has not observed daylight saving time since a short-lived experiment in 2009, so the gap between Bangladesh and every other zone is constant. Dhaka, the capital, is one of the most densely populated cities in the world. Because the country sits close to the middle of the UTC+06:00 band, solar noon is near 12:00 for most of the year. BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.

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 BDST and Kathmandu

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

Business hours overlap

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

BDST is 15 minutes behind Kathmandu (BDST UTC+06:00 → NPT UTC+05:45). The shared working window is 9:15 AM–5:00 PM BDST. Remember to re-check around daylight-saving transitions.
