Which country uses BST?

Could you please clarify which country typically utilizes British Summer Time, or BST? BST is a form of daylight saving time that is observed in various regions around the world, primarily in the United Kingdom and some of its territories. It's important to note that BST is not exclusive to a single country, but rather a timekeeping convention that adjusts clocks forward one hour during the summer months to make better use of daylight. So, while the United Kingdom is a notable example, there may be other countries or regions that also adopt BST as part of their timekeeping practices.
