Happy Birthday! I hope you have a great day today and the year ahead is full of many blessings.

May your birthday be sprinkled with fun and laughter. Have a great day!

Happy Birthday! I hope you have a fabulous day and be sure to eat an extra slice of cake for me!

I wish I could rewind the clock just to get back to the right time to say happy birthday. Please forgive me! I hope you had a great day.

I'm so sorry I forgot your birthday. The good news is that if you forget mine next year I'll forgive you. Happy Belated Birthday!

I'm so sorry I forgot your birthday. The good news is that I also forgot your age. Happy belated Birthday!

Sorry I missed your birthday by several days, but happy birthday anyways!

Happy Birthday! Don't think of this as a late birthday card. Consider it a very early one for next year. Here's wishing you a wonderful year ahead!

I know you think this card is a few days late. It's actually worse than that. This is your card from 2010 that I only just got around to sending. Happy Belated Birthday!

Dear [name], HBBD! That stands for Happy Belated Birthday! Love, YTDF (Your Terribly Disorganized Friend)

I promise this card isn't late. It is intentionally arriving after your birth-day, because I think you deserve a whole birth-month. Happy Birth-month!
