February 14 (valentine's day, of course, for those who are in a relationship) For those without a significant other, the advertisements, cards, flowers and attention given to this particular day make one acutely aware of one's lack of couplehood.

Alternate name for Valentine's Day (Feb. 14th), usually used in a negative sense by those who have no valentine.

February 14th, the day that every single man realizes "Damn, I forgot to get a girlfriend." Usually the wiser of the men realize this days ahead based on the many pink and red hearts and fluffy overpriced things found as they go to purchase their beer, or perhaps whilst sitting on the couch enjoying the rerun of 'Independence Day' realizing that every other television advertisement contains the word 'love' or a suggestion to the holiday most refer to as "Valentine's day".

Singles Awareness Day is also abbreviated "SAD" which can be found quite fitting to many people, ironic to the people in relationships, and quite clever to those who don't give a shit either way.

Celebrated or more like grieved on Valentine's day. S.A.D. stands for Singles Awareness Day. You get the point.

Valentine's Day for single people. I heard about it from a friend.

Feb. 13th, the day before Valentine's Day. Because so many people don't have relationships (or do, and they hate Valentine's Day anyway), Feb 13th is the day where single people do nothing, there are no cards, no flowers or anything like that.
