What To Write in a 40th Birthday Card

A 40th birthday can be a touchy subject, as people approach the milestone very differently! Their thirties are officially over, and they’re beginning to see “over the hill” but aren’t quite there yet. Whether you want to poke fun at their age or send a message straight from the heart, receiving a personalized 40th birthday card is sure to make their day. Here are a few different “Happy 40th birthday!” greetings you can try in your card:

  • Congrats on turning the big 4-0!
  • Happy 39th birthday… again!
  • Forty is fab, and so are you. Happy birthday!
  • Enjoy your 40s…they’re like your 20s only double as good!
