General elections is nominally held every 4 years, but the Prime Minister can at any point call a snap election. All Danish citizens over the age of 18 years who are living permanently within Denmark is eligible to vote, except those placed under legal guardianship. The same group of people is able to run for office. The electoral system is characterized as a party-list proportional representation system, with an election threshold on 2%. As a result, Denmark has a multi-party parliamentary system, where no single party has an absolute majority.
