Tips for a birthday message that lands

  • One specific memory beats three adjectives. "Still thinking about that terrible campsite in Wales" says more than "you're amazing and fun".
  • Mention the age only if they'd enjoy it. Milestones (18, 30, 50) are fair game; 37 usually isn't.
  • Use their birth date as a hook. A Leo's love of an audience or an April diamond gives you an opening line that is about them, not a generic card.
  • Edit the draft. Treat the generated message as a first version: swap in your own words and a name they actually go by.

Short birthday messages you can adapt

  • Another lap around the Sun. Glad I get to share the orbit with you.
  • Happy birthday! May this year be as bold as a Tiger and as lucky as a Rabbit.
  • Here's to the next 365 days, and to celebrating properly this weekend.
  • You don't look a day over whatever you've decided you are this year.

Questions people ask

How does the birthday message generator work?

It calculates facts from the birth date (the age they are turning, zodiac sign, Chinese zodiac, birthstone and flower) and asks an AI model to write a short card message in the tone you choose, weaving in one of those facts and any details you add.

Is it free?

Yes. There is a fair-use limit of a few messages every ten minutes to keep it free for everyone.

Is the information I type stored?

No. The birth-date facts, name and details are sent once to generate the message and are not saved by BirthdayBump.
