Denmark's climate is mild for a Scandinavian country -- New England farmers experience harsher winters. Summer temperatures average between 61°F and 77°F (16°C-25°C). Winter temperatures seldom go below 30°F (-1°C), thanks to the warming waters of the Gulf Stream. From the weather perspective, mid-April to November is a good time to visit.
Holidays -- Danish public holidays are New Year's Day, Maundy Thursday, Good Friday, Easter Sunday, Easter Monday, Labor Day (May 1), Common Prayers Day (fourth Fri after Easter), Ascension Day (mid-May), Whitsunday (late May), Whitmonday, Constitution Day (June 5), Christmas Day, and Boxing Day (December 26).
