If you have offices worldwide, it is useful to know which public holidays and subsequently, non-working days there are in each country.
Productive does this automatically. When you create a new subsidiary, Productive will ask you to assign it to a country:
Using this, Productive will generate a list of non-working days for that country. This will affect the capacity, availability, and scheduling of your teammates. As laws can change, you can edit the date of the holiday or you can add a custom non-working day as well by going into Settings - Holidays.
