How many working days in year 2065?

Here is the detail of the calculation:

Because 2065 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 8 public holidays that do not fall during a weekend and we obtain 253 working days in 2065.

Here is the list of these 8 public holidays:

1. Purim : воскресенье, 22 март, 2065
2. Pesach : вторник, 21 апрель, 2065
