How many working days in year 2087?

Here is the detail of the calculation:

Because 2087 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 6 public holidays that do not fall during a weekend and we obtain 255 working days in 2087.

Here is the list of these 6 public holidays:

1. Purim : вторник, 18 март, 2087
2. Pesach : четверг, 17 апрель, 2087
3. Shvi'i shel Pesach : среда, 23 апрель, 2087
4. Yom Ha-Atzmaut : среда, 7 май, 2087
5. Rosh Hashanah : воскресенье, 28 сентябрь, 2087
6. Yom Kippur : понедельник, 6 октябрь, 2087

And here are the 4 public holidays falling on a weekend:

1. Shavuot : пятница, 6 июнь, 2087
2. Rosh Hashanah : суббота, 27 сентябрь, 2087
3. Sukkot : суббота, 11 октябрь, 2087
