We're only three months away from one of the biggest events of the year: Prince Harry and Meghan Markle's wedding! The couple is getting ready to exchange "I dos" at 12 p.m. GMT on May 19 at St. George's Chapel at Windsor Castle. So what does that mean for us? Well, if you're planning on tuning in, you can do so from the comfort of your home at 4 a.m. PT. Let the royal wedding countdown begin!
