Morse Code Day

Morse Code Day is celebrated every year on April 27, the birthday of Samuel F. B. Morse, the American inventor and painter who helped create the telegraph and the code that carries his name. It is an unofficial holiday, not a public one, but it is a favorite among amateur radio operators, history buffs, and anyone who enjoys the dots and dashes. If you want to join in, you can start by sending your name in the translator.

Why April 27

The date is simply Morse's birthday. Samuel Morse was born on April 27, 1791, in Charlestown, Massachusetts. He trained as a painter and had a successful art career before he turned to the idea of sending messages instantly over wire, so the code was almost a second act for him. Tying the celebration to his birthday keeps the focus on the person, even though the practical dot-and-dash code owes a lot to his collaborator Alfred Vail as well. You can read more about both of them on the history page.

A very short history

Morse demonstrated a working telegraph in the late 1830s, and in 1844 he sent the famous first public message, "What hath God wrought," over a line between Washington and Baltimore. That moment kicked off the telegraph age and, with it, decades of Morse code as the backbone of long-distance communication. The original American Morse code was later revised into the International Morse code used worldwide today. For nearly a century, if a message crossed an ocean quickly, it very likely traveled as Morse.

How to celebrate Morse Code Day

You do not need any special gear to take part. A few easy ideas:

  • Learn to send your own name or initials. Type them into the translator and practice the rhythm.
  • Memorize the one signal everyone should know, SOS, which is three dots, three dashes, three dots.
  • Flash a short message to a friend with a flashlight using the light tool, then have them decode it.
  • Print the Morse code chart and keep it on your desk for the day.
  • If you are a licensed ham, get on the air and make a CW contact. Many operators plan a Morse session around the date.

Amateur radio clubs sometimes run special activity days near April 27, and you will see the date pop up every year in communities like r/amateurradio and r/morse, usually with people sharing their first decoded message or a photo of an old telegraph key. It is a low-key holiday, which is part of its charm.

Is it "Morse Code Day" or "International Morse Code Day"?

You will see both names. Some calendars call it Morse Code Day and others call it International Morse Code Day, but they refer to the same April 27 date and the same idea. There is no single official body that owns the holiday, so the naming is just a matter of preference.
