“What’s the difference between you and a calendar?”/“A calendar has a date on Valentine’s Day.”

A Valentine’s Day riddle is:
 
Q: What’s the difference between you and a calendar?
A: A calendar has a date on Valentine’s Day.
 
“What’s the difference between you and a calendar? a calendar has a date… LOL” was posted on Twitter on January 25, 2012. “What’s the difference between you and a calendar on valentine’s day? The calendar has a date” was posted on Twitter on January 26, 2012. The joke has been printed on many images (both with and without “Valentine’s Day”).
 
“Do you have a date for Valentine’s Day?”/“Yes. February 14th” is a different phrasing for the same Valentine’s Day “date” riddle.
