Why is National Julia Day on March 30?

Julia already has traditional name days across nine European countries, and May 22 is the most widely shared of them. March 30 is not one of those dates, and no source identifies who chose it or why.

Is National Julia Day the same as Julia Child Day?

No. Julia Child Day falls on August 15, the chef's birthday, and the City of Santa Barbara proclaimed it in 2019, while National Julia Day on March 30 is for everyone who carries the name.

Nobody has settled what Julia means: Latin scholars split between a Greek word for downy-bearded and the god Jupiter. March 30 gives the name a day that no Roman girl ever got to choose.

INTRO

Every daughter of every Julius was a Julia

National Julia Day celebrates a name that nobody in ancient Rome ever picked. A girl born into a citizen family did not receive Julia as a personal name. She inherited it, because every daughter of every man named Julius was a Julia.

That turned sisters into a filing problem. A household with more than one daughter told them apart as elder and younger, or as first, second and third. The name identified the family, not the girl.

Two thousand years later the name is still being handed out in bulk. In Poland it was the most-given girls' first name for twelve years running. What nobody can say is who put the day on March 30, or why that date rather than one of the many the name already keeps across Europe.

ORIGINS

Julia Day history

INTRODUCTION

One Julia had her life arranged for her from the day she was born. She arrived in 39 BC, the only child the emperor Augustus would ever have. Her mother Scribonia was divorced within days of the birth, and the girl grew up with her every word and action watched.

Augustus married her off three times, each match built for his succession. The first, Marcellus, died in 23 BC. When the second, Agrippa, died in turn, Augustus forced Tiberius to divorce his own wife and marry her instead.

CHAPTER 01

Exile on a rock off Campania

In 2 BC her father banished her to Pandataria. Livius describes the island, now called Ventotene, as less than 1.75 square kilometres and almost uninhabited. Scribonia went into exile with her daughter.

Julia died at Rhegium in AD 14, the year Tiberius took the throne and withheld her allowance. Rome never agreed about her. The fifth-century writer Macrobius called her witty and intelligent, and recorded that the people loved her.

CHAPTER 02

How the name got out of Rome

The name left the family and joined the church. Paul's letter to the Romans closes with greetings to a list of believers, and one of them is a Julia (Romans 16:15). Early saints and martyrs carried it too, among them the patron saint of Corsica.

Its masculine twin left the clearer trail. Julius was rare through the Middle Ages, and Italy and France revived it in the Renaissance before England imported it. Julia became common in English only in the 18th century, well after Shakespeare had given a heroine the name in The Two Gentlemen of Verona.

CHAPTER 03

A day arrives without a signature

The day itself is the one part of this story with no paper trail. No founder, organization, or proclamation is on record for National Julia Day, and nothing accounts for the choice of March 30. What is on record is that people mark it, including a Michigan public library that posted about missing the date and marked it late anyway.

TIMELINE

Timeline

An emperor's only child is born

Julia is born to Scribonia and the future emperor Augustus, who divorces her mother within days of the birth.

Banished to a bare island

Augustus exiles his daughter to Pandataria, now Ventotene, a nearly uninhabited island off the coast of Campania.

The Two Gentlemen of Verona gives an English comedy a heroine named Julia, more than a century before the name caught on in English.

In the first decade of American federal name data, Julia ranks 36th among girls' names, with 9,800 girls.

Poland's most-chosen girls' name

Julia takes first place on Poland's national register of girls' first names, ahead of Natalia and Wiktoria.

A Julia leads Australia

WHY THIS DAY MATTERS

Why We Love National Julia Day

CURRENT

A top-ten name in four European registries.

Behind the Name's popularity index puts Julia inside the ten most-given girls' names in the latest rankings for Spain, Catalonia, Poland and the Netherlands. The day is aimed at a name parents are still choosing, not one that survives only in the record.

STAYING

It never dropped off the American charts

The Social Security Administration has published the 200 most popular names for every decade since the 1880s, and Julia appears in all fifteen of those tables. Its worst decade across that entire span is 131st place.

MEANING

The meaning is still an open question

The Roman family name Julius is traced, tentatively, to a Greek word meaning downy-bearded. A rival reading points to Jupiter instead, and reference works still offer both as possibilities rather than a verdict.

How well do you know National Julia Day?

In ancient Rome, how did a girl end up with the name Julia?

Answer

No. It is an unofficial observance with no proclamation or resolution behind it in the Federal Register or the congressional record, so banks, schools and offices stay open.
