(CNN) - Move over, Valentine's Day, you've got some competition.
Nivea launched the first annual National PDA Day on Wednesday encouraging people to kick off summer and sunshine with a kiss.
The skin-care brand's website says it's a day dedicated "to making the world a more affectionate place."
And it looks like summer and love go hand in hand, according to research from one Arizona State University professor.
Americans also show more PDA during the summer than any other month.
The research also says Americans are more likely to marry and date in the summer-time.
