SAS EuroBonus - What's happening on 27th April in OSL?

Why are all flights seemingly full on SK and NO from OSL to CPH on Friday 27th April? School holidays?

It's a long weekend - Tuesday 1st of may is a national holiday and a lot of people get / take the Monday off as well such that it becomes a 4 day weekend.
(We have our lunch breaks cut from 30 to 25 mins but in return get all such days off without using holiday.)

Ah, the fine Scandinavian tradition of "squeeze-days" (klämdagar). When there is a single workday squeezed in between a public holiday and a weekend, nobody tends to show up for work ;)

In Russia (as well as in Ukraine, I believe) if public holiday ends up on Tuesday or Thursday respective Monday or Friday becomes day off at cost of some nearby Saturday
