HAPPY + BIRTHDAY
two signs, performed in sequence
"Happy birthday" — signed as two separate signs, one after the other.
For HAPPY, both open hands brush upward on your chest a couple of times, palms facing you — a motion often described as patting happiness upward. For BIRTHDAY, signers commonly combine the signs for "born" and "day." Exact hand shape and rhythm are easiest to learn by watching, not reading — see the note below.
More Ways to Say It
Unlike spoken languages, sign language doesn't really have "formal vs. casual" registers in the same way — but there are a few related signs worth knowing.
ASL Isn't Universal — Here's Why That Matters
A common misconception is that sign language is the same everywhere English is spoken — it isn't.
American Sign Language (ASL)
Used primarily in the US and parts of Canada. This page covers ASL specifically, since it's the overwhelming search intent for English queries.
British Sign Language (BSL)
A completely different, unrelated sign language used in the UK — despite both countries speaking English.
Learn From Video, Not Text
Hand shape, motion, and facial expression all matter in ASL. A short tutorial video from a reputable ASL source will teach the sign far more reliably than any written description, including this one.

Frequently Asked Questions
Is sign language the same in every English-speaking country?
No — American Sign Language (ASL), British Sign Language (BSL), and Auslan (Australia) are distinct, largely unrelated languages, despite all being used in English-speaking countries.
Is there one single, universal sign for "happy birthday"?
Generally it's a combination of the HAPPY and BIRTHDAY signs, though exact form can vary slightly by region or community — similar to accents or dialects in spoken language.
What's the best way to actually learn the sign correctly?
A short video tutorial from a reputable ASL resource is far more reliable than any text description, since hand shape, motion, and facial expression are all part of the sign and hard to capture in writing.
