Since the dates are 24/07/2009, that's July 24, 2009. Maybe this relates to a release or an event on that date. "Moona and Mirja" could be characters from a show, book, or game. If I can't find exact references, perhaps I should treat them as fictional characters.
I should structure the piece by first explaining the possible context, then the individuals or entities involved (Abbywinters, Moona, Mirja), the date significance, and details about the "fri new". Since information is limited, I should mention that details are speculative if not confirmed. abbywinters 24 07 09 moona and mirja with a fri new
