What time is it in London now, morning or afternoon (how to calculate British time?)

London is a famous international city in the world and the capital of the United Kingdom. For many people, knowing the exact time in London is important, especially when you need to have business meetings with people in London or when traveling. However, calculating time in London can be a bit confusing due to differences in time zones and changes to daylight saving time. In this article we'll detail how to accurately calculate time in London, as well as the division into AM and PM.

1. London’s time zone

The time zone in London is called “Greenwich Mean Time” (Greenwich Mean Time, GMT). GMT is the world's standard time, and other time zones are calculated relative to GMT. However, it is important to note that London adopts Daylight Saving Time during the summer, moving the time forward one hour, which is known as British Summer Time (BST). Therefore, when calculating time in London, we need to take into account changes to daylight saving time.

2. Calculate the time in London

To calculate the time in London, you first need to know your time zone. Take China as an example. The time zone in China is "China Standard Time" (CST), which is 8 hours different from GMT. So when the time in China is 9 am, the time in London is 1 am. When the time in China is 5 pm, the time in London is 9 pm.

However, when London adopts daylight saving time, the time needs to be moved forward one hour. Daylight saving time usually starts on the last Sunday in March and ends on the last Sunday in October. Therefore, during daylight saving time, when the time in China is 9 am, the time in London is 2 am. When the time in China is 5 pm, the time in London is 10 pm.

3. Division of morning and afternoon

In the UK, the division of morning and afternoon is different from that in China. In China, morning starts at 6 am and afternoon starts at 12 noon. However, in the UK, morning starts at 12am and afternoon starts at 12noon. So when the time in China is 9am, the time in London is 9am. When the time in China is 5 pm, the time in London is 5 pm.

4. Summary

In order to accurately calculate the time in London, we need to consider the differences in time zones and changes in daylight saving time. First, determine the difference between your time zone and GMT. Then, based on the start and end dates of daylight saving time, determine whether the time needs to be moved forward one hour. Finally, determine the specific time according to the British morning and afternoon division rules.

When having a business meeting or traveling to London, it is important to accurately calculate the time in London. I hope this article has been helpful and given you a better understanding of how time is calculated in London.
