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).

Comparing Time Zones: United Kingdom and China

United Kingdom runs on British Summer Time (BST) at UTC+01:00, currently observing daylight saving time. China runs on China Standard Time (CST) at UTC+08:00. That puts United Kingdom 7 hours ahead of China — a difference of +7h at the current offsets.

In practice, when it is 9:00 AM in United Kingdom it is 4:00 PM in China. Midnight in United Kingdom is 7:00 AM in China.United Kingdom observes daylight saving time while China does not, so the gap narrows or widens by an hour part of the year.

Why people convert United Kingdom to China time

Scheduling a call from United Kingdom to China: a 10:00 AM start in United Kingdom lands at 5:00 PM in China, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both United Kingdom and China are inside the 9-to-5 working day between 9:00 AM and 10:00 AM BST time (4:00 PM–5:00 PM CST). That is roughly 1 hours of usable overlap.
Watching a live event or market open: United Kingdom viewers need 4:00 PM in China to catch a 9:00 AM start there, and 5:00 PM if the event is anchored to United Kingdom.

Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +7h gap is not.
Block 9:00 AM–10:00 AM BST as the recurring meeting window if you work primarily from United Kingdom and need China colleagues present.
United Kingdom: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +7h gap.

About GMT (Greenwich Mean Time)

Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

About CST (China Standard Time)

China Standard Time (CST, also known as Beijing Time) is used across all of mainland China despite the country spanning five geographical time zones. This single-timezone policy was adopted in 1949. China does not observe daylight saving time. CST is shared with Hong Kong (HKT), Macau, Taiwan, Singapore, Malaysia, and the Philippines, making UTC+08:00 one of the most used offsets in the world.

Best time to call between United Kingdom and China

Both United Kingdom and China sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM BST, which is 4:00 PM–5:00 PM CST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

United Kingdom and China overlap for only 60 minutes (9:00 AM–10:00 AM BST), so meetings have to be booked precisely.

United Kingdom is 7 hours ahead of China (BST UTC+01:00 → CST UTC+08:00). The shared working window is 9:00 AM–10:00 AM BST. Remember to re-check around daylight-saving transitions.
