Happy June 5th to you Danes out there!
5 June - Constitution Day
5 June is the anniversary of the coming in force of the first Danish Constitution, the June Constitution of 1849. The day, which in many places is a full or half holiday, is celebrated around the country with political rallies, which especially formerly were in the nature of popular festivals, for instance on the popular nature spots Himmelbjerget and Skamlingsbanken in Jutland.
It is also Fatherís Day, which was introduced from the USA in 1935.
