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 10 public holidays that do not fall during a weekend and we obtain 251 working days in 2100.

Here is the list of these 10 public holidays:

1. New Year's Day : пятница, 1 январь, 2100
2. Good Friday : пятница, 26 март, 2100
3. Victoria Day : понедельник, 24 май, 2100
4. Canada Day : четверг, 1 июль, 2100
5. Labour Day : понедельник, 6 сентябрь, 2100

9. Christmas (observance) : понедельник, 27 декабрь, 2100
