How many working days in year 2085?

Here is the detail of the calculation:

Because 2085 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 2085.

Here is the list of these 7 public holidays:

1. Pesach : вторник, 10 апрель, 2085
2. Shvi'i shel Pesach : понедельник, 16 апрель, 2085
3. Yom Ha-Atzmaut : вторник, 1 май, 2085
4. Shavuot : среда, 30 май, 2085
5. Rosh Hashanah : четверг, 20 сентябрь, 2085
6. Sukkot : четверг, 4 октябрь, 2085
7. Shemini Atzeret / Simchat Torah : четверг, 11 октябрь, 2085

And here are the 2 public holidays falling on a weekend:
