Easter was 40 days ago, meaning that today is Ascension Thursday. In Sweden it’s a national holiday, and since there’s just one more day until weekend, many will be taking tomorrow off too. This means that today is actually the start of a four-day weekend.
This occurs almost every time a workday gets squeezed in between a holiday and the weekend. So whenever we get a Tuesday or Thursday off, we also take the Monday or Friday off respectively as a bonus to get four days off work.
These bonus days off are called klämdagar (“squeeze days”) in Swedish, and everyone here loves them.
