About time in Alderney
Only about three miles long, Alderney is the closest of the Channel Islands to France, about eight miles from Cap de la Hague. France is one hour ahead of the island, so a short trip across the Alderney Race changes the clock by an hour.
Alderney has its own States of Alderney, which handles local matters, while defence and foreign affairs rest with the Crown through the UK.
The island is known for its puffins and gannets, the Alderney Week festival in August and the Alderney Race, one of the strongest tidal races in Europe, which makes the clocks on tide tables essential for sailors. Tide times are quoted in local time, which follows GMT or BST.
Flights to Alderney from Southampton and Guernsey take 15 to 40 minutes, with flight times in local UK time. Alderney is about 2.2 degrees west of Greenwich, so sunrise is about nine minutes later than in London.
- About 2,000 residents.
- Capital: St Anne.
- France is one hour ahead of Alderney.
