What should I Do On My Birthday 12/28?

That is really going to depend on how much you want to spend, what you like to do etc. I would get a pedicure (love those) go to a couple of after Christmas sales and buy a new sweater or something colorful, then go to a bakery and ask them to make some special cupcakes for me, buy live flowers, and maybe go out to a sushi dinner. But that is just me!
