The Dutch celebrate this 5-5-…. ,this was the day the germans signed their surrender.
O wait history also says 6-5-1945 and since their was no royalty present this is not a legal document.
The Queen vacated her seat in the govrnement in 1940 by leaving for England.
Germans/nazi's filled the position and it was really not legally given back.
The Netherlands is still a provence of Germany??
