The Holiday Committee organises activities at certain holidays.
For example, the Winter Holidays Activity where we celebrate Christmas, 'Sinterklaas' (the Dutch Santa Clause) and New Years Eve. Furthermore, they hand out roses on Valentines day, bake pies at Pi Day or hide easter eggs on Easter. But don't limit yourself to the conventional holidays. Every holiday can be celebrated (such as Talk-like-a-Pirate Day)!
The committee consists of approximately five people and organises these activities. Organising the Holiday activities does not cost a lot of time (or money). Creativity does come in handy sometimes.
There was a Holiday Committee in these years:
