A couple of days late to the party but during this Lockdown period the days are all merging in to one! I could have sworn yesterday was Thursday (it was in fact Tuesday).
If you haven't heard, Koningsdag is celebrated on the 27th April every year. This huge festival is to celebrate King Willem-Alexander's Birthday. Both Tourists and the Dutch flock to their nearest Cities to celebrate in style from morning to late into the night. Orange is the Royal's colour therefore the streets and people choose to be covered in orange clothing, flags and other novelties.
