About this time
The United Kingdom uses GMT in winter and BST (UTC+1) in summer via Europe/London. London is the default reference for UK business, media, and international finance sessions overlapping with Europe.
United Kingdom uses the IANA zone Europe/London. The offset adjusts automatically for daylight saving time when applicable.
Daylight saving and seasonal changes
BST starts on the last Sunday of March and ends on the last Sunday of October—the same calendar as most of the EU.
Practical tip
UK time is one hour behind Central European Time in winter and matches it during BST, which simplifies calls with Paris or Berlin for half the year.

FAQ
Why can the displayed time shift during the year?
Many regions change their official offset twice a year for daylight saving time. We hold one absolute instant internally (UTC) and convert using the curated IANA zone for that moment.
Why do some countries have several time zones?
Large countries such as the United States, Canada, Russia, or Brazil cover several offsets. We show the primary zone and let you pick others when available.
How does the comparator work?
Pick two to four countries, set a reference country with a date and time, and the tool projects that instant to every row.
