Because flowers in February makes no sense and every day should be an opportunity to show people that you love them, not just once a year. We still get to keep the candy companies happy, the restaurants will lose a chance to price gouge, but bars will have increased liquor sales for a week instead of one sad lonely night. Also, I believe it goes without saying, but: Costumes. Halloween in February means a costume-focused festival instead of a skin showoff. People helping people. Did I mention costumes?
