Hello AutoGen,

Unfortunately, you asked the question about holidays very superficially, as this is very much based on religious cult and the reference to timekeeping.

Holidays in cultures that follow the moon cannot be implemented using the Logo.

However, this is possible for cultures that follow the Gregorian calendar. To do this, you first have to derive the current date from the Logo and then calculate Easter Sunday as the basis for the variable holidays in your country.
