Leap Day!

This year February 29 falls within Lent. This is an interesting day for several reasons. It is a remarkable quirk of the calendar that it has a movable day that appears only once in four years. This variable is necessary to make our solar calendar work and even then it needs the occasional tweaking. February 29 is a rare day and I find that fascinating.
I am also fascinated by the day because it is my dad's birthday. He only has a birthday every four years, so this is his 15th birthday.
Happy Birthday Dad!
