(1) there are 11 days of national holidays in Singapore.
(2) 52 weeks x 2 = 104 days of Saturday and Sunday.
(3) approximately 14 days of annual leaves.
Add them all up, and most of us are actually not working for 129 days a year.
And that equates to you not working on 129/365 = 35% of the days. It could be even more if you add in MCs, or if your company gives you more annual leaves.
So cheer up, for every 3 days, you get to rest for slightly more than 1 day.
