About time in Guernsey
Sark, a short boat ride away, has no cars and was designated the world's first Dark Sky Island in 2011, so many visitors plan a night around the clock and the moon, not just the sun.
Guernsey follows the UK and EU clock-change dates, so its time is the same as London all year. It is one hour behind France and the rest of Central Europe.
- About 63,000 residents.
- Capital: St Peter Port.
- Sark was named a Dark Sky Island in 2011.
