Happy Valentine's Day

[Malte279]

I agree that they might have their own holidays but would definitely not celebrate any holiday derived from human religions. Celebrating Valentine's day millions of years before the birth of St. Valentine would be just as unlikely as the dinosaurs celebrating Christmas.
I suppose their celebrations would be more based on observation of nature (e.g. longest / shortest day of the year or the like) or other things that they can sense.
