Still trying to make my first post

I have placed it here to be checked on. Appears to be a Swedish film but I cannot find it in IMDB or here on a search. I got it from the Newsgroup.

No subtitles so difficult to follow but title is something to do with an invitation (birthday?). A young boy and girl meet at a play area and the film becomes surreal towards the end.
