You can get one Good Friday a year if you live in a country that treats it as bank holiday, or is Catholic enough that it's effectively a day off, even if not an official one.

You can get extra Fridays off if you move to a country with bank holidays that tend to land on Fridays, which is correlated with history of either communism or organized religion (much like the weekend).

But, if you want every Friday off, your best bet is to embrace hyper-capitalism and worm your way money so you can have four-day work week.

(Easier to achieve than the legendary four-hour work week anyway.)

TL;DR: the more opposing ideologies you can simultaneously hold, the more days off in a week you're morally entitled to :).
