How many working days in year 2002?

Here is the detail of the calculation:

Because 2002 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 2002.

1. Pesach : Thursday, 28 March, 2002
2. Shvi'i shel Pesach : Wednesday, 3 April, 2002
3. Yom Ha-Atzmaut : Wednesday, 17 April, 2002
4. Rosh Hashanah : Sunday, 8 September, 2002
5. Yom Kippur : Monday, 16 September, 2002

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

1. Shavuot : Friday, 17 May, 2002
