How many working days in year 2051?

Here is the detail of the calculation:

Because 2051 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 7 public holidays that do not fall during a weekend and we obtain 253 working days in 2051.

Here is the list of these 7 public holidays:

1. Goede Vrijdag : Friday, 31 March, 2051
2. Tweede Paasdag : Monday, 3 April, 2051

6. Eerste Kerstdag : Monday, 25 December, 2051
7. Tweede Kerstdag : Tuesday, 26 December, 2051
