National Day, or Ullortuneq, is observed in Greenland every June 21. This major national holiday celebrates Greenland's national and cultural values across all settlements and towns. The day was introduced in 1983 as part of the Home Rule traditions following Denmark's grant of Home Rule to Greenland in 1979. The date was chosen as it coincides with the longest day of the year. Celebrations typically include morning songs, speeches, and the hoisting of the Greenlandic flag, followed by a church service. People often wear national costumes and carry small flags, and festivities include kaffemik, local entertainment such as music and folk dance, and displays of kayaking skills. Additionally, June 21 marks the anniversary of Denmark granting further autonomy to Greenland in 2009.
