Post-election
Polls close at 21:00 and the votes are counted immediately. For national elections, the first results usually come within the first five minutes after the polls are closed (from the municipalities with the fewest inhabitants, Schiermonnikoog and Renswoude). The final results are generally known around midnight and semi-officially announced the next morning, after which the 150 seats are allocated. However, recounting over the course of the following days sometimes throws up minor shifts in the allocation of seats.
