It feels like you just had a birthday the other day. Oh yeah, sorry I am late. Happy birthday.

My best wishes to you, even though are belated.

I might have forgotten your birthday, but at least I got a gift for you.

Sorry I missed your birthday. I swear that this only happens to me like once a year.

Better late than never? Hope you had the most amazing birthday.

Sorry I forgot your birthday. Can you reschedule it for sometime next week?

I hope all your birthday wishes came true.

Even though this message comes to you a little late, the wish it brings for happiness is good on any day date. Happy belated birthday.
