How many working days in year 2031?

Here is the detail of the calculation:

Because 2031 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 2031.

Here is the list of these 8 public holidays:

1. Nytårsdag : Wednesday, 1 January, 2031
2. Skærtorsdag : Thursday, 10 April, 2031
3. Langfredag : Friday, 11 April, 2031

7. Juledag : Thursday, 25 December, 2031
8. 2. juledag : Friday, 26 December, 2031
