Also, it's important to note that two Swedish red days always fall on Saturdays: Midsummer Day and All Saints' Day. In 2017, there were "only" 8 red days on Mon-Fri, plus two unofficial red days of Midsummer Eve and All Saints' Eve.
Same for Denmark and Norway.
Here in Japan any public holiday falling on a Sunday will become on a Monday. The bank holidays in the UK are the same.
