Happy Birthday in Morse code is …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.–, two words, 13 letters, 41 signals. It is the longest greeting phrase in common Morse use. If you have already learned something like I love you or I miss you, this one will take more work. But it has something built into its structure that makes it easier than it looks: the letter H appears in both words, and Y closes both words. The phrase rhymes with itself in Morse.
What Is “Happy Birthday” in Morse Code?
The full pattern is …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.–. Two words separated by a word gap. The slash marks that gap, seven units of silence.
Here is how the signal weight breaks down between the two words:
| Word | Morse Code | Letters | Signals |
|---|---|---|---|
| HAPPY | …. .- .–. .–. -.– | 5 | 18 signals |
| BIRTHDAY | -… .. .-. – …. -.. .- -.– | 8 | 23 signals |
| Total | …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.– | 13 | 41 signals |
BIRTHDAY is five signals heavier than HAPPY despite being only three letters longer. That comes down to which letters are in each word. BIRTHDAY contains B, R, and D, all of which are 3 or 4 signals each, plus it has H and Y again.
Happy Birthday in Morse Code: Letter by Letter
13 letters. A few of them show up twice. That is part of what makes this phrase stick once you learn it.
| Letter | Morse Code | Dots and Dashes | Spoken (dit-dah) | Signals |
|---|---|---|---|---|
| HAPPY | ||||
| H | . . . . | dot dot dot dot | dit-dit-dit-dit | 4 signals |
| A | . – | dot dash | dit-DAH | 2 signals |
| P | . – – . | dot dash dash dot | dit-DAH-DAH-dit | 4 signals |
| P | . – – . | dot dash dash dot | dit-DAH-DAH-dit | 4 signals |
| Y | – . – – | dash dot dash dash | DAH-dit-DAH-DAH | 4 signals |
| BIRTHDAY | ||||
| B | – . . . | dash dot dot dot | DAH-dit-dit-dit | 4 signals |
| I | . . | dot dot | dit-dit | 2 signals |
| R | . – . | dot dash dot | dit-DAH-dit | 3 signals |
| T | – | dash | DAH | 1 signal |
| H | . . . . | dot dot dot dot | dit-dit-dit-dit | 4 signals |

| A | . – | dot dash | dit-DAH | 2 signals |
| Y | – . – – | dash dot dash dash | DAH-dit-DAH-DAH | 4 signals |
| HAPPY = 18 | BIRTHDAY = 23 | Total signals in HAPPY BIRTHDAY | 41 | ||
Three things worth noticing in that table. First, H appears twice: once at the start of HAPPY and once in the middle of BIRTHDAY. Same four-dot pattern both times. Learn H once and you get it in both words for free.
Second, Y closes both words. HAPPY ends on Y and BIRTHDAY ends on Y. The same heavy pattern, dash-dot-dash-dash, lands at the end of each word. The phrase has a structural echo built into it.
Third, T is the single easiest letter in the whole phrase. One dash. That is all. BIRTHDAY contains T right in the middle and it is the only 1-signal letter in the entire Morse code alphabet. When you hit T while tapping, it is one long hold and you move straight on.
How to Say “Happy Birthday” in Morse Code
14 sounds, one phrase. The double-P in HAPPY is the most unusual part: two identical patterns back to back, like the double-S in I miss you but longer.
How to Tap “Happy Birthday” in Morse Code
41 signals is a lot to hold in your head all at once. The trick is not to learn it all at once.
Learn it in three parts, not two. HAPPY on its own. Then BIRTH (B-I-R-T-H, 14 signals). Then DAY (D-A-Y, 9 signals). BIRTHDAY broken into BIRTH and DAY is much more manageable than treating it as one 23-signal block. Once each part feels automatic at slow speed, connect them one at a time. HAPPY plus BIRTH first, then add DAY. The double-P in HAPPY is the first real challenge, two identical 4-signal patterns back to back with just a letter gap between them.
Use the player above set to slow speed and listen for the anchors: H is four quick beeps, and it appears twice. If you can identify H by ear, you can orient yourself in both words. Y is the heavy landing at the end of both words: long-short-long-long. Once you can pick out H and Y, the rest of the phrase fills in around them. Play it until those two markers are automatic before trying to recognise the whole phrase.
Sending …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.– in a birthday message or posting it on someone’s wall lands completely differently than just writing happy birthday. Most people will not know what it says. The right person will. It is a small, specific thing that takes actual effort, which is exactly why it works as a birthday gesture.
The Numbers Behind “Happy Birthday” in Morse
41 signals is a lot. To understand what that actually means, here is where Happy Birthday sits among phrases you might already know:
| Phrase | Signals |
|---|---|
| No | 5 signals |
| OK | 6 signals |
| Yes | 8 signals |
| SOS | 9 signals |
| Hello | 16 signals |
| I miss you | 22 signals |
| I love you | 24 signals |
| Happy Birthday | 41 signals |
Happy Birthday is almost double the length of I love you. A birthday greeting in Morse takes significantly more effort than a declaration. That is probably appropriate. Saying happy birthday is a whole thing. I love you is three words. Happy birthday is a performance.
Of the 13 letters in Happy Birthday, seven of them are 4-signal letters (H, P, P, Y, B, H, Y). Only one letter has fewer than 2 signals, and that is T with its single dash. Everything else sits at 2, 3, or 4. This phrase does not rush. It settles into each letter and takes its time, which is exactly how a good birthday greeting should feel.
If you are curious how I love you sounds in comparison, the I Love You in Morse Code page has the full 24-signal breakdown. Both are worth learning, for completely different reasons.
“Happy Birthday” in Other Languages in Morse Code
If you want to wish someone happy birthday in their language, the Morse just changes with the words. A few of the most common translations:

|---|---|---|
| Spanish | Feliz cumpleanos | ..-. . .-.. .. –.. / -.-. ..- — .–. .-.. . .- –.— |
| French | Joyeux anniversaire | .— — -.– . ..- -..- / .- -. -. .. …- . .-. … .- .. .-. . |

| Italian | Buon compleanno | -… ..- — -. / -.-. — — .–. .-.. . .- -. -. — |
| Indonesian | Selamat ulang tahun | … . .-.. .- — .- – / ..- .-.. .- -. –. / – .- …. ..- -. |

Ways to Use “Happy Birthday” in Morse Code
Write the full pattern under or instead of “Happy Birthday” in a physical card. Most people will not know what it says. If the person knows Morse, they will. Either way it is more interesting than just writing the words.
41 signals in dot-dash form makes a distinctive visual. Bracelets, necklaces, ring engravings, and personalised gifts with …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.– are genuinely meaningful to people who know what they are looking at.
Posting the Morse pattern on someone’s birthday on a social wall or in a message takes maybe three seconds and lands completely differently than a gif or an emoji. It signals that you took a moment to look it up. That counts.
If you are on a video call and the other person knows Morse, tap it out on the desk. At normal speed, 41 signals takes about eight seconds. It is a good eight seconds.
Frequently Asked Questions
Happy Birthday in Morse code is …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.–. That is 41 signals across 13 letters and two words. HAPPY is …. .- .–. .–. -.– (18 signals) and BIRTHDAY is -… .. .-. – …. -.. .- -.– (23 signals).
41 signals total, making it the longest common greeting phrase in Morse. HAPPY contributes 18 (H=4, A=2, P=4, P=4, Y=4) and BIRTHDAY contributes 23 (B=4, I=2, R=3, T=1, H=4, D=3, A=2, Y=4). For comparison, I love you is 24 signals and Hello is 16 signals.
In Morse code the phrase is …. .- .–. .–. -.– / -… .. .-. – …. -.. .- -.–. You can tap it, flash it with a light, send it as audio, or write the dots and dashes in a birthday message. The player at the top of this page lets you hear exactly how it sounds at different speeds.
Three letters appear twice. H (….) appears at the start of HAPPY and inside BIRTHDAY. A (.-) appears in HAPPY and near the end of BIRTHDAY. Y (-.–) closes both words. Learning these three letters once gives you their patterns in two places each, which makes the phrase easier to learn than it first looks.
T. It is one dash. That is the entire code for T, and it is the only 1-signal letter in the whole Morse alphabet. BIRTHDAY contains T right in its middle. When you get to it while tapping, it is one long hold and you continue.
I love you in Morse code is .. .-.. — …- . / -.– — ..-, 24 signals across 8 letters. Happy Birthday is 41 signals across 13 letters, nearly double the length. A birthday greeting in Morse takes considerably more effort than a declaration of love. The full I love you breakdown is on the I Love You in Morse Code page.
Break it into three pieces rather than two. Learn HAPPY as one unit, BIRTH (B-I-R-T-H) as a second, and DAY (D-A-Y) as a third. Once each piece is automatic at slow speed, connect HAPPY and BIRTH, then add DAY. The double-P in HAPPY needs the most attention because two identical 4-signal patterns run back to back with only a letter gap between them.
Want to hear the full 41 signals? Use the audio player above and try slow speed first. Listen for H at the start of HAPPY and again in BIRTHDAY: that four-dot anchor is what ties the whole phrase together.
