It is one of those dates that feels etched into the collective memory of the world, yet somehow, it remains just a number on a page until you really sit with it. Anne Frank was born on June 12, 1929. She came into a world that was, on the surface, relatively normal in the city of Frankfurt, Germany. But if you look at the timeline of the early 20th century, that year was a tipping point. She wasn't born into a vacuum. She was born exactly when the Weimar Republic was starting to fray at the edges.
Honestly, when you think about the question of when is Anne Frank born, you have to look at the hospital records from the Maingau Red Cross Clinic. It was a Wednesday. Her parents, Otto and Edith, were already raising her older sister, Margot, who was three at the time. They were a typical liberal Jewish family. They didn't live in a "Jewish quarter." They lived in a diverse neighborhood on Marbachweg. Anne was a loud baby. A "spunky" kid from day one.
The World in 1929: A Heavy Year for a Birthday
Context matters. If you just memorize June 12, 1929, you’re missing the point. That was the year of the Great Depression. The stock market crashed just months after she was born. In Germany, this wasn't just about money; it was the fuel for the fire of radicalism.
While Anne was learning to crawl, the Nazi party was gaining seats in the Reichstag. It's a chilling realization. Her entire infancy was synchronized with the rise of the very regime that would eventually force her into a hidden annex in Amsterdam.
Most people don't realize that the Franks were German citizens. They weren't "refugees" in the way we think of them today until the Nuremberg Laws stripped them of their identity. When Anne was born, her father was a businessman who had served as an officer in the German army during World War I. He was a patriot. He probably thought his children would grow up as proud Germans.
Life in Frankfurt was briefly sweet. There are photos of Anne as a toddler, playing in the sand, looking exactly like any other kid from the late twenties. She had these big, dark eyes that seemed to take in everything. Her mother, Edith, kept a baby book. She recorded Anne's first words and steps. It's so painfully ordinary.
Moving to Amsterdam
By the time Anne was four, everything changed. 1933 was the year Hitler took power. That’s when the question of where she lived becomes as important as when Anne Frank was born. The family realized Germany wasn't safe. Otto moved to Amsterdam first to set up a business—Opekta, which sold pectin for jam-making. Anne and her mother stayed behind with her grandmother in Aachen for a bit before joining him.
Imagine being five years old and moving to a country where you don't speak the language. Anne did it. She thrived. She went to a Montessori school. She made friends like Hanneli Goslar and Sanne Ledermann. To her, 1934 to 1939 were years of freedom. She was a Dutch girl in every way that mattered. She loved ice skating. She loved film stars. She was obsessed with the Dutch Royal Family.
The Birthday That Changed History: June 12, 1942
We have to talk about her 13th birthday. If you're looking for the most significant moment related to when she was born, it’s this one. On June 12, 1942, Anne woke up and found a small, red-and-white checkered diary among her presents.

"I hope I will be able to confide everything to you, as I have never been able to confide in anyone, and I hope you will be a great source of comfort and support."
That was the first entry. She didn't know that in less than a month, her sister Margot would receive a call-up notice for "labor" in Germany, forcing the whole family into hiding. That diary, given to her because it was her birthday, became the most famous document of the 20th century.
It’s weird to think about. If she had been born a year later, or a year earlier, maybe the diary wouldn't have been the gift. Maybe she wouldn't have had the maturity to write the way she did. She was exactly the right age—a precocious, somewhat moody, incredibly observant teenager—at exactly the wrong time in history.
Common Misconceptions About Her Early Years
A lot of people think Anne was born in Holland. She wasn't. She was a German refugee. Another thing? People often assume she was always "Saint Anne."
If you read the unedited versions of her diary, you see a girl who could be kind of a brat. She was sharp-tongued. she clashed with her mother constantly. She was "the spicy one" compared to the "perfect" Margot. This is why her story resonates. She wasn't a symbol; she was a girl who liked movies and complained about her housemates.
- Birthplace: Frankfurt am Main, Germany.
- Birth Weight: 8.25 pounds (roughly).
- Astrological Sign: Gemini (which, if you believe in that stuff, totally fits her talkative, dual-natured personality).
- The "Kitty" Name: Her diary wasn't always called Kitty. That came later, inspired by a series of books by Cissy van Marxveldt.
Why Does the Date June 12 Matter Today?
Every year, the Anne Frank House and schools around the world use June 12 as a day of reflection. It’s called "Anne Frank Day." It’s not just a celebration of a writer; it’s a benchmark for human rights.
When we look at when Anne Frank was born, we are looking at the fragility of democracy. In 1929, Germany was a modern, cultured, technological society. Within fourteen years of her birth, that same society had built a system to systematically erase people like her.
It’s also worth noting the age gap. If Anne were alive today, she would be in her late 90s. There are people still living who were born in 1929. When you frame it that way, the Holocaust doesn't feel like "ancient history." it feels like yesterday. It’s within the span of a single human life.
Looking at the Records
If you’re doing deep research, you’ll find her birth certificate under the name Annelies Marie Frank. The "Anne" was a nickname that stuck. The archives in Frankfurt still hold the census data from that era. You can see the names of her neighbors. You can see the shops that were on her street.

Researchers like Melissa Müller, who wrote one of the most definitive biographies of Anne, emphasize that her early childhood in Frankfurt was actually quite happy. This is the tragedy. Her life didn't start in a dark attic. It started in a sunlit apartment with a family that had every reason to believe they belonged.
What You Can Do Now
Knowing the date is just the start. If you want to actually honor the history behind when Anne Frank was born, you need to engage with the primary sources.
First, read the "Definitive Edition." Many people only read the version edited by her father, Otto, in the 1940s. He cut out a lot of her more "teenager" moments—her comments on puberty, her harsher critiques of her mother, and her burgeoning sexuality. The newer versions give you the real Anne.
Second, visit the digital archives. The Anne Frank House in Amsterdam has an incredible online collection. You can see high-resolution scans of the actual red-checkered diary. Seeing her handwriting—which starts out very "child-like" in 1942 and becomes much more sophisticated by 1944—is a gut punch.
Third, support modern education. There are organizations like the Anne Frank Center for Mutual Respect that use her life to teach about contemporary prejudice.
Finally, check out the genealogy. Understanding the Frank and Holländer family trees helps you see the scale of the loss. Most of Anne’s extended family did not survive. When you look at the birth dates of her cousins and aunts, you see entire branches of a family tree pruned in the 1940s.
Anne Frank wasn't just a girl in an attic. She was a girl from Frankfurt, born in a year of economic chaos, who happened to have a pen and the courage to use it. Her birth date isn't just a fact for a history quiz. It's a reminder of how quickly the world can turn upside down.
