Early on Sunday 26 March 2017 Swiss clocks move forward one hour. Officially time changes at 2am. This means you will miss one hour of sleep and it will be darker when you get up. On the up side, it will be lighter for longer in the evenings.
The rest of Europe will adjust its clocks at the same time.
On Sunday morning the sun will rise at 7:26am and set at 19:56, according to timeanddate.com. The longest day of the year is 21 June 2017.
