What is Valentine's Day all about anyway?

There is sometimes a sense among Christians that since (1) Valentines Day isd after Saint Valentine and (2) the BIble is big on "love", that Valentines Day must be a Christian holiday. Not so says Christianity Today.

So why do people send "valentines" or "love-tokens" to one another on that day? The origin of that tradition is not thought to have any connection with the saint's day. Rather it comes from an early European belief that the second week of February was when birds began to mate. The idea suggests that lovers should probably exchange notes and gifts on February 14 in conjunction with what nature practiced.

This is not to say that exchanging tokens of affections is WRONG. It is a nice and quaint practice. But it has nothing to do with Christianity.
