Replying to Drinking on Birthday?

Okay I know this is a little random, but my birthday is next sunday. I am wondering if they would let me drink at 12:01am sunday morning down in salt lake. I have heard that a ton of bars in the city won't serve someone during their "power-hour' or until a certain point on their birthday. This sounds completely ridiculous to me being from ohio where they hand out shots like candy, but one of my friends swears that a lot of bars won't serve you. This would absolutely blow being that my birthday is on a Sunday and a bunch of friends are coming into town. I have also heard that park city is a different story. Any info would be appreciated
