When you live in Sweden, you will get acquainted with ”klämdag.”
If a public holiday happens on a Thursday or Tuesday, there will be one day, a Monday or Friday, between the holiday and the weekend. It's squeezed in between the holiday and weekend. ”Klämdag” means ”squeeze-day” in Swedish. Many Swedes take the opportunity to take a day off on ”klämdagar” to have a long weekend. If, for instance, a national holiday is on a Thursday, you can take Friday ”klämdag” off and have four whole days free.
Yesterday was Ascension Day in Sweden. Since it was a Thursday, today is a typical klämdag.
