How many working days in year 2001?

Here is the detail of the calculation:

Because 2001 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 2001.

Here is the list of these 8 public holidays:

1. Pesach : воскресенье, 8 апрель, 2001
2. Yom Ha-Atzmaut : четверг, 26 апрель, 2001
3. Shavuot : понедельник, 28 май, 2001
4. Rosh Hashanah : вторник, 18 сентябрь, 2001
5. Rosh Hashanah : среда, 19 сентябрь, 2001
6. Yom Kippur : четверг, 27 сентябрь, 2001
7. Sukkot : вторник, 2 октябрь, 2001
