How many working days in year 2000?

Here is the detail of the calculation:

Because 2000 is a leap year, it has 366 days.

Let's remove 53 saturdays and 53 sundays. It remains 260 days.

Now, let's remove 10 public holidays that do not fall during a weekend and we obtain 250 working days in 2000.

1. New Year's Day : Monday, 3 January, 2000
