Western European Summer Time is also known by other names:
- British Summer Time (BST) in the United Kingdom.
- Irish Standard Time (IST) (Am Caighdeánach na hÉireann (ACÉ)) in Ireland. This is sometimes called Irish Summer Time (Am Samhraidh na hÉireann).
The scheme runs from the last Sunday in March to the last Sunday in October each year. At both the start and end of the schemes, clock changes take place at 01:00 UTC. During the winter, Greenwich Mean Time (UTC+0) is used.
