The last day of February. Traditionally this is the day that the lady in a relationship get's her man a new golf club in anticipation of spring and the start of golf season.

If the man doesn't play golf then she should get him something related to his favorite activity.

If the lady gets the man something for Golf Club Day he is expected to return the favor on Jewelry Day.
Ryan: Dude, what did your wife get you for Golf Club Day?

Rob: I don't play golf so she got me the hot new XBOX game.

Ryan: Now you gotta get her something for Jewelry Day.
