How many working days in year 2067?

Here is the detail of the calculation:

Because 2067 is not a leap year, it has 365 days.

Let's remove 52 saturdays and 53 sundays. It remains 260 days.

Now, let's remove 5 public holidays that do not fall during a weekend and we obtain 255 working days in 2067.

Here is the list of these 5 public holidays:

1. Pesach : четверг, 31 март, 2067
2. Shvi'i shel Pesach : среда, 6 апрель, 2067
3. Yom Ha-Atzmaut : среда, 20 апрель, 2067
4. Rosh Hashanah : воскресенье, 11 сентябрь, 2067
5. Yom Kippur : понедельник, 19 сентябрь, 2067

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

1. Shavuot : пятница, 20 май, 2067
2. Rosh Hashanah : суббота, 10 сентябрь, 2067
3. Sukkot : суббота, 24 сентябрь, 2067
