On months with less than 31 days, when the third ring in hits the last day of the month, it just skips to the first?

The Javascript just recomputes a new absolute rotational position for the rings on every update. So in effect it is always skipping, so it would skip in that case like all others.

My thoughts exactly, and what about leap years?
