Roughly a fifth of all English boys in the later Middle Ages were named John, a name that once faced almost no competition.
No documented founder or formal establishment record has been identified for National John Day. Holiday-listing sites carry the September 25 date, but none names an originator and no primary record has been found.
In the later Middle Ages, John was given to approximately a fifth of all English boys. Not a fifth of the names in use, a fifth of the boys. National John Day belongs to a name that once faced almost no competition.
The day itself arrived without paperwork, and with a name that invites a mix-up. National John Day is September 25. St. John's Day, the ancient feast for John the Baptist, falls on June 24.
Two names, two days, two entirely different things. The name is the part with a paper trail.
John began as a sentence rather than a label. In Hebrew it is Yoḥanan, built from yo, which refers to God, and ḥanan, which means to be gracious. Read whole, it says Yahweh is gracious.
The English form arrived by relay. Yoḥanan became the Greek Ioannes, then the Latin Iohannes, then John. How that particular sentence took over a continent is the harder question.
The name was in use long before the church had anything to do with it. A high priest named Johanan was active around 407 BC. King John Hyrcanus, another early bearer, died in 104 BC.
John the Baptist was a Jewish ascetic, considered the forerunner of Jesus. The apostle John is traditionally regarded as the author of the fourth gospel and Revelation. Between them they put the name into common use.
Adoption was uneven. The name was initially more common among Eastern Christians in the Byzantine Empire. It flourished in Western Europe only after the First Crusade.
Then it settled in and refused to leave. By the 1200s John was the most common male name in England. It typically held that rank there into the 1900s.
The reign ended slowly. John was the most popular name given to male infants in the United States until 1924. Robert took the top spot in the 1920s and did not give it back for decades.
Nobody has claimed the day that sits at the end of this story. No founder, establishing document or organization behind it has surfaced, and no source records why the date is September 25. The name is documented from ancient priests to modern government tables; the day named for it is documented nowhere.
TIMELINE
WHY THIS DAY MATTERS
Six days on the church calendar already belong to one John.
John the Baptist is commemorated on six separate days in the church calendar. One of them, the Beheading, falls on August 29.
John is theophoric, a name with a god's name inside the personal one. Hebrew carries a longer form of it too, Yəhôḥānān.
The nativity of John the Baptist is kept in the Catholic, Eastern Orthodox, Anglican and Lutheran churches. It carries a colloquial name of its own, Johnmas.

No. It is an unofficial observance with no legal standing, so it is a normal working day.
COLOPHON
Before 1066 Thomas appears in England only as a priest's name; it went on to become common enough to stand for anyone taken at random.
Aaron cracked America's top 100 boys' names in 1968 and never left, a 56-year streak only 19 names share; not bad for a name the reference books decline to translate.
Any Beth, Betty, Eliza, Libby, Lisa or Isabel is invited too: all are forms of Elizabeth, one name worn a dozen ways for centuries.
