March 27. That is the short answer. But if you ask Mariah Carey herself, she might tell you she doesn't actually have a birthday. She has "anniversaries."
Honestly, it’s one of the most Mariah things ever. For decades, fans and journalists have been locked in a low-stakes but high-drama debate: was she born in 1969 or 1970? If you look at her own words, she’s "eternally 12." But the paper trail? That tells a slightly different story.
When is Mariah Carey's birthday and why is there a mystery?
Most people just celebrate their big day with a cake and some awkward singing. Mariah Carey turned her birth date into a philosophical stance. Technically, her birthday is March 27. However, the year has been a moving target for a long time.
For the longest time, bio sheets and early press releases listed her birth year as 1970. Even her mother, Patricia Carey, told Oprah Winfrey in a 1999 interview that Mariah was born in 1970. You'd think a mother would know, right? Well, the plot thickened when fans started digging into the archives.
The 1969 vs. 1970 Debate
Researchers and dedicated "Lambs" (her fanbase) eventually found a birth announcement in The Long Islander newspaper. The date? April 10, 1969. The announcement noted that a daughter was born to Mr. and Mrs. Alfred Roy Carey on March 27.

Mathematically, that puts her birth in 1969.
Why the discrepancy? Some think the record label wanted her to be a "70s baby" to make her seem younger when she debuted in 1990. Others think it was just a clerical error that took on a life of its own. In the grand scheme of things, one year doesn't change much. But in the world of pop superstardom, image is everything.
The "Eternally 12" Philosophy
Mariah doesn't just ignore the year; she basically rebukes the concept of time. She famously told Out Magazine that she doesn't count years. "I have anniversaries, not birthdays, because I celebrate life, darling," she said. It’s iconic. It’s camp. It’s also a very savvy way to never have to deal with the "how old are you" question from nosy reporters.
She often claims she is "eternally 12." This isn't just a random number. She feels that 12 was the age when she truly found her voice and her identity. By staying 12 in her mind, she keeps that creative spark alive.

- No Clocks: She has admitted in interviews, specifically with Capital FM in 2025, that she doesn't even like clocks.
- Anniversary Celebrations: Instead of a birthday party, she has "anniversary adventures."
- The 3:27 Tradition: She once shared a video of herself jumping into the ocean at exactly 3:27 PM on March 27.
How the World Celebrates the Chanteuse
Even if Mariah refuses to acknowledge the ticking clock, the rest of the world doesn't. Every March 27, social media turns into a giant "Happy Anniversary" card.
In 2024, she celebrated her "55th anniversary" (by 1969 standards) with a stunning selfie on a yacht. She wore a sequined indigo gown that basically screamed mermaid royalty. Her fans didn't post "Happy 55th." They posted "Happy Anniversary, Queen." They know the rules. You don't mention the "A-word" (age) around Mimi.
Real Evidence vs. Public Persona
If you look at the U.S. Copyright Office, many of her earliest songs registered in the mid-80s list her birth year as 1969. Her children's birth certificates, however, reportedly list her birth year as 1970. It’s a classic case of a celebrity choosing their own reality and sticking to it so hard that the rest of us eventually just go along with it.
Is it a lie? Is it a "fairyland experience"?

It’s probably a bit of both. In a world that is obsessed with aging women out of the spotlight, Mariah’s refusal to play the game is actually kind of revolutionary. She’s essentially saying that her age is irrelevant to her art. And honestly? She’s right.
What You Should Know for the Next Anniversary
If you want to celebrate like a true Lamb, there are some ground rules. First, never use the word "birthday" in her mentions. Use "anniversary." Second, the festivities don't just last a day; it’s usually a whole season.
- Wear something festive: Preferably something that sparkles or has a butterfly on it.
- Listen to the high notes: Put on "Emotions" or "Fantasy" and appreciate the fact that time hasn't touched those pipes.
- Ignore the calendar: If Mariah can ignore 1969, you can ignore whatever deadline you have on March 27.
Actionable Insights for Fans
If you're looking to track Mariah Carey's birthday or just want to stay in the loop with her latest "anniversary adventures," here is how to stay updated:
- Follow her Instagram: This is where the "Anniversary Adventures Commence" posts usually happen.
- Check the News in Late March: Major outlets like People and Entertainment Tonight usually cover her celebrations, often quoting her latest hilarious stance on the passage of time.
- Use the 1969 Reference for Accuracy: If you are writing a biography or a formal report, 1969 is the year backed by archival newspaper records and early copyright filings. If you are writing a fan tribute, stick with the "anniversary" vibe to stay in her good graces.
Ultimately, whether she was born in 1969 or 1970 doesn't change the fact that she’s the most successful female songwriter and performer of her era. She has 19 number-one hits. She "owns" Christmas. If she wants to be 12 years old forever, we should probably just let her.
