How many working days in year 2050?

Here is the detail of the calculation:

Because 2050 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 2050.

Here is the list of these 5 public holidays:

1. פסח : Thursday, 7 April, 2050
2. שביעי של פסח : Wednesday, 13 April, 2050
3. יום העצמאות : Wednesday, 27 April, 2050
4. ראש השנה : Sunday, 18 September, 2050
5. יום כיפור : Monday, 26 September, 2050

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

1. שבועות : Friday, 27 May, 2050
2. ראש השנה : Saturday, 17 September, 2050
3. סוכות : Saturday, 1 October, 2050
