How many working days in year 2040?

Here is the detail of the calculation:

Because 2040 is a leap year, it has 366 days.

Let's remove 52 saturdays and 52 sundays. It remains 262 days.

Here is the list of these 5 public holidays:

1. Pesach : четверг, 29 март, 2040
2. Shvi'i shel Pesach : среда, 4 апрель, 2040

4. Rosh Hashanah : воскресенье, 9 сентябрь, 2040
5. Yom Kippur : понедельник, 17 сентябрь, 2040

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

1. Shavuot : пятница, 18 май, 2040

3. Sukkot : суббота, 22 сентябрь, 2040
