Happy Annual Solar Rotation Day. Celebrating your birthday is just you making another rotation around the Sun. For those who are born Feb 29, there are no birthdays for 3 years. What they do have are Solar rotation days.
Hey, whats an obnoxious/nerdy way to say "Happy Birthday"?

Tell them its their HASR Day! For today, they've revolved around the Sun one more time!
