By Anna Duncan

In this article, we will explore the current time in London and whether it is AM or PM. London, the capital city of the United Kingdom, follows Greenwich Mean Time (GMT) during standard time and British Summer Time (BST) during daylight saving time.

What is GMT?

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory located in Greenwich, London. It serves as a reference point for timekeeping worldwide. GMT does not observe daylight saving time adjustments and remains constant throughout the year.

What is BST?

British Summer Time (BST) is observed in London and other parts of the United Kingdom during the summer months. It starts on the last Sunday in March when clocks are set forward by 1 hour, advancing from GMT to GMT+1. BST ends on the last Sunday in October when clocks are set back by 1 hour, returning to GMT.

The Current Time in London

The current time in London can be determined based on whether it is currently observing GMT or BST.

If it is currently observing GMT:

In London, if it is currently observing Greenwich Mean Time (GMT), you would need to refer to Coordinated Universal Time (UTC) to find the current time. UTC is a global standard for timekeeping.

  • To find out the current UTC time:
  • Check your local time offset from UTC.
  • Add your local time offset to the current UTC time.

For example, if your local time offset from UTC is -5 hours and the current UTC time is 12:00 PM, then in London, it would be 5:00 PM (GMT).

If it is currently observing BST:

In London, if it is currently observing British Summer Time (BST), you would need to consider the time offset from GMT+1.

  • To find out the current BST time:
  • Check your local time offset from GMT+1.
  • Add your local time offset to the current BST time.

For example, if your local time offset from GMT+1 is -4 hours and the current BST time is 2:00 PM, then in London, it would be 10:00 AM (BST).

Conclusion

The current time in London depends on whether it is observing Greenwich Mean Time (GMT) or British Summer Time (BST). By considering the appropriate time offsets, you can determine whether it is AM or PM in London.

Remember to check for any daylight saving adjustments when calculating the current time in London as it transitions between GMT and BST. Stay aware of any changes in local time offsets to ensure accurate calculations. Now you have the tools to determine whether it’s AM or PM in London!
