How many working days in year 2100?

Here is the detail of the calculation:

Because 2100 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 7 public holidays that do not fall during a weekend and we obtain 254 working days in 2100.

Here is the list of these 7 public holidays:

1. New Year's Day : пятница, 1 январь, 2100

5. Good Friday : пятница, 26 март, 2100
6. Mesadi : среда, 14 апрель, 2100
7. Christmas Eve : пятница, 24 декабрь, 2100

And here are the 3 public holidays falling on a weekend:

1. Independence Day : воскресенье, 15 август, 2100
