Are you an August baby? Well, join the club. More people celebrate their birthdays in August than any other month (about 9% of the population).

July and September are next in line. (This would mean November and December are fairly, um, busy months behind closed doors. New Year’s Eve is also a popular time to procreate, making October 5 the most frequent birthday in the U.S.)

Now, if you’re born on May 22nd or February 29th, consider yourself an oddity; it is the least common birth date of the year.

Speaking of oddities, if a garden snail starting crawling on your last birthday, it would have tracked 263 miles by your next birthday. (Take that one to the bank.)

The most popular rendition of Happy Birthday? Well, you can probably guess that one. “Happy Birthday, Mr. President” was sung by actress and singer Marilyn Monroe on Saturday, May 19, 1962, for President John F. Kennedy at a celebration for this 45th birthday at the third Madison Square Garden in New York City.

Monroe’s performance was notable for several reasons. It was one of her last public performances before she died on August 5, 1962. Monroe was also allegedly having an affair with President Kennedy, which gave her racy, intimate performance a whole new meaning.

Monroe’s dress is almost as famous as her performance that evening. The dress was so skintight, Monroe had to be sewn into it (and of course, she wore nothing underneath). Under stage lights, the fabric, chock full of sparkling rhinestones, had a melting away effect, adding to the sexiness. It sold at an auction in 1999 for a cool $1.26 million.

Close to 2 billion birthday cards are sent each year in the U.S. alone, accounting for nearly 58% of all cards sent. So if you have a loved one with a birthday coming up (or you simply want to be part of a 2 billion person movement), check out our wide array of birthday e-cards.
