In Italy we work approximately 220 days a year, 5 days a week, we have 52 weekends (as everybody else) 24 days of payed holidays and another 10 days of national holidays.

six months, 6 days a week it's about 160 days.

Working an hour and half more everyday day is like working 7/7, so about 185 working days.

It's totally doable.

But admittedly not for a long time and not if you're forced to do it
