Week-ends are the main operating time of a planetarium. Saturday and Sunday afternoons are normally reserved for the astronomical standard shows. Some planetaria exchange their principal topics in a certain cycle, others offer their broad spectrum of issues in accord to a variable schedule. Music shows prevail in the evenings, they are not offered in every place, though. Concerts with live music or radio plays, readings and movie presentations are dispersed to all days of the week on average.

After the start of the show, no entrance is permitted. This action suits the safetiness of the visitors. The star hall is pitch-dark, and late comers would not orient themselves while searching for a seat. The same reason holds for the re-entry after a possible leaving. Mobile phones have to be swiched off. Smoking is not permitted neither in the star hall nor in the foyer. Pets also have no access.
