Constitution Day (Danish: Grundlovsdag) is observed in Denmark on 5 June.^[1][2] The day honours the Constitution of Denmark, as both the first constitution of 1849 and the current constitution of 1953 were signed on this date of their respective years.^[3] Denmark is one of only a handful countries in the world not to have an official national day, but Constitution Day is sometimes considered the equivalent of such a day, and a day for celebrating Danish democracy.

Though it has never been an official national holiday, Constitution Day was a half-day off work from 1891 until 1975. Since then, collective labour agreements have usually given workers a half-day or the whole day off on Constitution Day.^[4] Stores with an annual turnover of at most 43.4 million kroner can stay open on Constitution Day, but most stores must keep closed.^[5]

The day is widely celebrated throughout Denmark with church congregations, associations and political organisations meeting for what are essentially "secular services".^[3] These services include the raising of the Dannebrog (the Danish flag), a short speech by a local politician or celebrity, and collective singing (Danish: fællessang).
