How many working days in year 2047?

Here is the detail of the calculation:

Because 2047 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 5 public holidays that do not fall during a weekend and we obtain 256 working days in 2047.

Here is the list of these 5 public holidays:

1. Pesach : четверг, 11 апрель, 2047
2. Shvi'i shel Pesach : среда, 17 апрель, 2047
3. Yom Ha-Atzmaut : среда, 1 май, 2047
4. Rosh Hashanah : воскресенье, 22 сентябрь, 2047
5. Yom Kippur : понедельник, 30 сентябрь, 2047

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

1. Shavuot : пятница, 31 май, 2047
2. Rosh Hashanah : суббота, 21 сентябрь, 2047
3. Sukkot : суббота, 5 октябрь, 2047
