The lower profile February 2 holiday

Although it isn't as well-known as Groundhog Day, former family cat Rosie once declared February 2 Calico Day.  She would look for her shadow upon waking up February 2.  If she saw it, she decreed there would be an early Spring.  If she didn't see it, she still decreed there would be an early Spring.  Although this same end result in either case compromised the suspense, I would still listen for her decree.  Here she is in 2007, after having seen her shadow:

With a countenance this serious, I wasn't about to argue with her early Spring decree.
