How many working days in year 2105?

Here is the detail of the calculation:

Because 2105 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 7 public holidays that do not fall during a weekend and we obtain 254 working days in 2105.

Here is the list of these 7 public holidays:

1. Pesach : вторник, 31 март, 2105
2. Shvi'i shel Pesach : понедельник, 6 апрель, 2105
3. Yom Ha-Atzmaut : вторник, 21 апрель, 2105
4. Shavuot : среда, 20 май, 2105
5. Rosh Hashanah : четверг, 10 сентябрь, 2105
6. Sukkot : четверг, 24 сентябрь, 2105
7. Shemini Atzeret / Simchat Torah : четверг, 1 октябрь, 2105
