One for the steps

Rico says that, having one of each, we should also celebrate Stepmother's Day and Stepfather's Day.
He hereby declares that the second Sunday in November shall henceforth be Stepmother's Day and the third Sunday in December shall henceforth be Stepfather's Day. (That's six months, or a step-year, off the traditional dates.)
Consider yourself officially notified and, if you have a step-anything, put them in your calendar.
