Today is the first day of the recently announced curfew in the Netherlands. The curfew is from 21:00 to 04:30 every day until at least 9 February. If you are outside without a valid reason and official form then you face a €95 fine. You can download the official form at rijksoverheid.nl, with the form currently available in Dutch, Frisian and English.

This of course means that grocery stores and late-night convenience stores need to closer earlier:
Curfew will not affect starting times of football matches from nltimes.nl. Which makes sense – this way at least people have something to watch on television while they are stuck at home.
