How many working days in year 2030?

Here is the detail of the calculation:

Because 2030 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 6 public holidays that do not fall during a weekend and we obtain 255 working days in 2030.

Here is the list of these 6 public holidays:

1. Purim : вторник, 19 март, 2030
2. Pesach : четверг, 18 апрель, 2030
3. Shvi'i shel Pesach : среда, 24 апрель, 2030
4. Yom Ha-Atzmaut : среда, 8 май, 2030
5. Rosh Hashanah : воскресенье, 29 сентябрь, 2030
6. Yom Kippur : понедельник, 7 октябрь, 2030

And here are the 4 public holidays falling on a weekend:

1. Shavuot : пятница, 7 июнь, 2030
2. Rosh Hashanah : суббота, 28 сентябрь, 2030
3. Sukkot : суббота, 12 октябрь, 2030
