How many working days in year 1910?

Here is the detail of the calculation:

Let's remove 52 saturdays and 53 sundays. It remains 260 days.

Now, let's remove 8 public holidays that do not fall during a weekend and we obtain 252 working days in 1910.

Here is the list of these 8 public holidays:

1. Pesach : воскресенье, 24 апрель, 1910
2. Yom Ha-Atzmaut : четверг, 12 май, 1910
3. Shavuot : понедельник, 13 июнь, 1910

7. Sukkot : вторник, 18 октябрь, 1910
