Happy Birthday in Morse Code
Thirteen letters of celebration. “Happy birthday” is one of the longest phrases people send in Morse — and one of the most fun, because it turns an everyday greeting into a puzzle worth decoding.
How to write “happy birthday” in Morse code
Happy birthday in International Morse code is ···· ·− ·−−· ·−−· −·−− / −··· ·· ·−· − ···· −·· ·− −·−−. Letter by letter:
Long as it looks, the phrase is friendlier than it appears: it reuses letters generously. H appears twice, A twice, P twice in a row, and Y closes both words with the same swooping −·−−. Learn nine distinct letters and you own all thirteen — every one verifiable on the alphabet chart.
How it sounds
HAPPY runs di-di-di-dit di-dah di-dah-dah-dit di-dah-dah-dit dah-di-dah-dah — the doubled P gives it a cheerful, skipping repeat, like a little drum fill. BIRTHDAY answers with a longer, statelier line. Type the phrase into the Morse code translator, slow the speed down, and listen for the twin P patterns — once you hear them, you'll always recognise HAPPY.
Turn it into a birthday surprise
On a card
Write the dots and dashes on the front and the translation inside — the birthday person gets a puzzle before they get the message. The translator gives you a clean, correct pattern to copy.
As sound or light
Download the phrase as a WAV file and text it as an audio message, or flash it with your phone torch at the party — the flash mode shows the exact timing. Our guide to Morse by light flashes and taps has technique tips.
On a gift
Like LOVE and I love you, birthday messages work beautifully as Morse jewellery or engraving — dots as small beads, dashes as bars. Thirteen letters make a long pattern, so bracelets usually carry just HAPPY BDAY or the person's name instead; verify any shortened version in the translator before it goes on metal.
A quick learning path
Don't memorise the phrase cold. Steal from words you may already know: H and A from thank you, Y from yes, I and R from other basics. Then practice HAPPY and BIRTHDAY as separate words for a day each. The full method — and why spaced daily practice beats cramming — is in our guide to learning Morse code.
Try it yourself
Open the Morse code translator, type HAPPY BIRTHDAY, and press Play to hear it — or turn on the flash and vibrate options to see and feel the rhythm. You'll find more everyday examples on our common Morse code words page, and a full study plan in the guide to learning Morse code.
Frequently asked questions
It’s ···· ·− ·−−· ·−−· −·−− / −··· ·· ·−· − ···· −·· ·− −·−− — HAPPY, the word gap, then BIRTHDAY. Hear it in the translator.
Short flashes for dots, long for dashes, a pause between letters and a longer one between words. Rehearse with the flash mode in our translator first — thirteen letters rewards a little practice.
Usually yes — thirteen letters is a lot of beads. Most people shorten it to HBD or use the person’s name on the bracelet, and save the full phrase for the card.
