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.

Now, let's remove 5 public holidays that do not fall during a weekend and we obtain 257 working days in 2040.

Here is the list of these 5 public holidays:

1. Pesach : Thursday, 29 March, 2040
2. Shvi'i shel Pesach : Wednesday, 4 April, 2040
3. Yom Ha-Atzmaut : Wednesday, 18 April, 2040
4. Rosh Hashanah : Sunday, 9 September, 2040
5. Yom Kippur : Monday, 17 September, 2040

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

1. Shavuot : Friday, 18 May, 2040
2. Rosh Hashanah : Saturday, 8 September, 2040
