Thanks for your reply.
Yes, I can copy stuff from private to public calendar, but I want to import e.g. public holidays and other "events" that covers the whole year.
It is too big a job to copy them one by one.
And I can´t find a way to mark them up to copy them in batches.
I´m looking for a way to fill all year form a text file.
Maybe it´s not possible?
