How many working days in year 2017?

Here is the detail of the calculation:

Because 2017 is not a leap year, it has 365 days.

Let's remove 52 saturdays and 52 sundays. It remains 261 days.

Now, let's remove 7 public holidays that do not fall during a weekend and we obtain 254 working days in 2017.

Here is the list of these 7 public holidays:

1. Pesach : вторник, 11 апрель, 2017
2. Shvi'i shel Pesach : понедельник, 17 апрель, 2017

6. Sukkot : четверг, 5 октябрь, 2017
7. Shemini Atzeret / Simchat Torah : четверг, 12 октябрь, 2017
