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 BST to Nairobi time

Scheduling a call from BST to Nairobi: a 10:00 AM start in BST lands at 12:00 PM in Nairobi, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both BST and Nairobi are inside the 9-to-5 working day between 9:00 AM and 3:00 PM BST time (11:00 AM–5:00 PM EAT). That is roughly 6 hours of usable overlap.
Booking travel or deliveries: tracking Nairobi local time against BST keeps pickup windows and arrival estimates honest across the +2h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +2h gap is not.
Block 9:00 AM–3:00 PM BST as the recurring meeting window if you work primarily from BST and need Nairobi colleagues present.

About BST (British Summer Time)

British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.

About EAT (East Africa Time)

East Africa Time (EAT) is used in the countries of East Africa including Kenya, Ethiopia, Tanzania, Uganda, and others. EAT does not observe daylight saving time and shares the same offset as Moscow Standard Time (MSK).
