I guess I have a different view of bizarre. I thought these would be wierd holidays from the past or very different holidays they celebrate in other countries we wouldn't be used to in North America. It seems they have official days for everything now but these are not holidays. I do not find chess bizarre or that the US has an official day for it wierd.
Having said this the actual content of the box was good quality, nice magnetic chess set, interesting water bottle representing the King or Queen (my daughter loved this) and a book that looks very interesting.
Not exactly bizzare or wierd but good products.
