Are post game party events in random order?

I finish the main story and plat the game already, so i'm just playing for fun and this question sudennly appear on my mind. Do the weekly party events have a specific order or are they random? I have a lobster party in 2 days. Is there a way to know what party will come next? It would be great if I could farm spices, vegetables and fish based on what's coming next week!
