Prince Harry and Meghan Markle [1] have many things in common [2], but their age isn't one of them. In fact, there's a three-year age difference between Harry, 33, and his 36-year-old fiancée. Meghan was born on Aug. 4, 1981 [3], and Harry was born on Sept. 15, 1984 [4].

Another fun, age-related fact: when Harry and Meghan tie the knot next Spring at St. George's Chapel [5] at Windsor Castle, Kensington Palace, Meghan will make British royal family history by becoming the oldest royal bride [6]. Meghan will take over the record that is currently being held by the Duchess of Cambridge [7], who is also a few months older than Prince William. Further proof that age really isn't anything but a number!
