In this post, we uncover what makes September babies unique – from their astrological signs to science-proven personality traits.

Let’s dive in!

Welcome, fall! So long, summer.

As you know, September is the 9th month, which begins the final quarter of the year.

In the Northern hemisphere, it marks the beginning of autumn and the end of summer. In the Southern hemisphere, in countries like Argentina or South Africa, it’s the start of spring.

The autumn equinox typically falls on September 22 or 23. It is a wonderful month to have a baby, as it’s a time of change. Colorful leaves fall from the trees. The last of the hot air of summer is stirred by refreshing fall breezes, promising new possibilities and a path to a new year ahead.

Get ready: September also means that the holidays are just around the corner. By December, your newborn will already be a 3-month-old infant—so remember to capture lots of adorable holiday photos while you can!

What does September mean?

The name September comes from the Latin word “septem,” which means seven. Why seven? Because September used to be the seventh month in the old Roman calendar, which began in March.

The old Roman calendar was used until as late as 153 B.C. Even though the calendar was eventually adjusted to add January and February, turning the seventh month to the ninth, the name September was not changed.

September Holidays and Special Dates

September has its fair share of significant dates and celebrations. Here are some of the most interesting dates that parents like to know when they’re expecting a September baby:

  • Labor Day: Celebrated on the first Monday of September, Labor Day is a U.S. national holiday that honors workers. It’s also considered the unofficial end of summer, when many American children go back to school after the summer break.
  • Talk Like a Pirate Day (September 19): Ahoy! Among the more bizarre holidays, this one has become one of the most well-known around the world. The celebration involves just what you think: talking like a swashbuckling pirate.
  • Rosh Hashanah: A 2-day holiday, Rosh Hashanah is the Jewish civil New Year. It’s a celebration of the creation of life, occurring each year 163 days after Passover.
  • Yom Kippur: Known as the Day of Atonement, Yom Kippur is the holiest day of the year in Judaism and for many means 25 hours of fasting and prayer. Each year, it begins at sundown on the 10th day of the Jewish month of Tishrei, 9 days after the first day of Rosh Hashanah.
  • Oktoberfest: Beer lovers know that Oktoberfest in Germany actually begins in mid-September, and ends the first weekend of October. So, your baby’s arrival is the perfect time for a toast—cheers!

Also notable in September: the start of the NFL season and “Baby Safety Month.”

September Birthstones & Flowers

September has several birth flowers: the forget-me-not, the morning glory, and the aster, all of which represent forms of love. Specifically, forget-me-not flowers represent love and memories. Aster also represents love and morning glory flowers represent unrequited love. These are all considered to be passionate flowers due to their vibrant colors and spectacular blooms.

The birth stone for the month is the sapphire. Sapphire is usually envisioned as a blue stone, but it also comes in green, pink, purple, and clear. The blue sapphire in particular represents clarity of thought, intuition, and peacefulness. In certain cultures, it has been believed to have medicinal properties and has been used to treat fevers and inflammation. Black sapphire is seen as a grounding and protecting stone. Some believe that sapphire reduces anxiety and procrastination and gives the wearer good luck.

Astrology & Zodiac

A baby born in September is either Virgo (August 23-September 22) or Libra (September 23-October 22). Here’s what this could mean for your baby’s personality traits in the future, according to the zodiac:

  • Virgo: Virgo is a mutable earth sign which is ruled by the planet Mercury. Virgos are well known for their industrious, reliable natures. If a Virgo is given a task, as a child or as an adult, he or she will work toward completion and excellence of that task. Virgos seek the same excellence in their interpersonal relationships as they do in their work and studies, but they tend toward being more critical of other people than they are of themselves. What do Virgos look for in others? They seek stability, and this is true in the workplace and in the home as well. If your baby is a Virgo, it will be your job to provide a stable environment as he or she grows up (the same for all zodiac signs, really, but your little Virgo will especially crave that stability). When your child becomes an adult, that stability will be carried on to his or her own family.
  • Libra: If your newborn is a Libra, he or she will likely have very clear ideas of what is right or wrong, and will seek for balance in interpersonal relationships. Libras work toward harmony at home and at work, and are very interested in the people around them. If you have a Libra child, make sure to remember that he or she may not express everything in the interest of preserving the peace—so you should take extra care that he or she is happy in the deepest sense.

Both Virgos and Libras are very harmonious signs, so you can look forward to a balanced and personable child!

Personality Traits Proven by Science

Not everybody believes in the tenets of astrology, and that’s okay! If you’re curious what other factors might contribute to your September baby’s personality, simply look to science.

Research has shown that people born in certain months do tend to display similar patterns of personality traits. So, what does this mean for babies born in September?

Here’s what the data tells us:

  • Low levels of depression: Babies born in the fall, including September, tend to be less depressed as adults, research shows. Similarly, they are less likely than people born in other seasons to develop bipolar disorder. Scientists don’t yet have a reason why this may be. But some believe it may have something to do with how our species has benefited from harvest season, when food and nutrients are most bountiful.
  • Irritability: They may not get as depressed, but September-born people can get irritable. Research shows that those born in the fall tend to experience higher rates of irritability.

It’s worth noting that this research applies to adults, not babies – and they’re based on patterns, not definite personality traits. Your baby’s personality will naturally blossom over the next few years, as influenced by a wide range of factors, from genetics to the other personalities in your home.

Milestones: How soon will my baby … ?

Once you know your due date, it’s easy to predict when your baby will hit various developmental milestones. Yes, every baby is unique – and if you have multiple kids, then you know how differently their development can be in those first few years. Still, you can use general timelines to predict roughly when these big events will occur.

Here’s when your September baby will:

  • Crawl: Most likely between April and July of next year (7 to 10 months)
  • Walk: Probably sometime between summer and Christmas (about 9 to 15 months)
  • Smile: Not too long now! Your baby’s first smile (not from gas) should occur before the end of December (6 to 12 weeks)
  • Eat solid food: Probably sometime between January and March (4 to 6 months)
  • Laugh: Get ready! Baby’s first laugh should come by the New Year (approximately 4 months)

When was your conception date?

It’s fun to think about your baby’s earliest beginnings, isn’t it? And since you know that your conception is roughly 40 weeks prior to your due date, then you might be able to narrow down “when it all began.”

Figuring out your conception date can be fun for expectant parents, because sometimes it can tell you interesting things that were happening in your life at the time.

For example, if your baby is born in September, that means your conception date was last December or January.

Ring any bells? Your baby was conceived right around the holidays. Were you traveling? What was the weather? What were you watching on Netflix? Tiny details like these can provide an interesting backdrop to the “story” of your pregnancy.

September in History

Okay, so you won’t be able to tell much about your baby’s personality based on history. But it can be fun to know that your baby was born on the same date as significant historical events. Here are a few big ones in September:

  • VJ Day (September 2, 1945): “Victory over Japan,” which marked the end of World War II.
  • Patriot Day (September 11, 2001): Remembrance for victims of the terrorist attacks of September 11, 2001.
  • Treaty of Paris signed (September 3, 1783): The official end of the American Revolutionary War.
  • S. Constitution approved (September 17, 1787): Delegates from 12 states voted unanimously to approve the constitution.
  • Creation of United States Army (September 29, 1789): Congress created the first official U.S. Army following the Revolutionary War, consisting of 1,000 enlisted men and officers.
