How many working days in year 2081?

Here is the detail of the calculation:

Because 2081 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 2081.

Here is the list of these 6 public holidays:

1. Purim : вторник, 25 март, 2081
2. Pesach : четверг, 24 апрель, 2081
3. Shvi'i shel Pesach : среда, 30 апрель, 2081
4. Yom Ha-Atzmaut : среда, 14 май, 2081
5. Rosh Hashanah : воскресенье, 5 октябрь, 2081
6. Yom Kippur : понедельник, 13 октябрь, 2081

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

1. Shavuot : пятница, 13 июнь, 2081
2. Rosh Hashanah : суббота, 4 октябрь, 2081
3. Sukkot : суббота, 18 октябрь, 2081
