Our four picks, then everything day by day. Something that runs for days counts on each of them.

Other cities
Everything that is free in each city over the next seven days.
Questions
01Is everything here really free in Leiden?
Everything the organiser lists as free or pay-what-you-like in Leiden. Sometimes you have to sign up first, or the organiser asks for a donation (that is stated with the outing). Check the organiser's site before you go.
02How do you choose the picks?
In order of what makes it special: one-off or not, who plays and how well it fits the season. Where we can, a pick says why.
03What is not included?
Online events, lectures, courses, weekly classes, church services and business meetings.
