Before Taylor Swift's transition from a country/pop sweetheart to a crazed vengeful victim, I was a huge fan of hers. I've been listening to her music for as long as I can remember.

Over the years, as an observant T Swift fan, I've noticed her penchant for mentioning ages in her songs. Maybe she does this so she can look back on these songs and remember how old she was when she had these experiences. Or maybe she does it so her fans have another level to relate to her on. For at least my past seven birthdays, I've checked to see if Taylor Swift mentioned my new age in one of her songs.

Not only does it make me feel closer to her, but it also gives me a song to cling to for a while. By my count, Taylor Swift mentions 13 different ages in her songs.

1. 3

This is the youngest age mentioned in a Taylor Swift song, which means you probably didn't listen to this song on your third birthday. This age comes from the song The Best Day off of her second album, Fearless. The song chronicles Swift's life at multiple ages and is above all a love letter to her family.

The lyrics:

"There is a video I found from back when I was three. You set up a paint set in the kitchen and you're talking to me. It's the age of princesses and pirate ships and the seven dwarfs."

2. 5

This is another age mentioned in The Best Day. It is part of the song's opening line. Unlike age three, where Swift is seeing something and not actually remembering it, this appears to be a memory from age five with her mother sometime in October.

The lyrics:

"I'm five years old, it's getting cold. I've got my big coat on. I hear your laugh, and look up smiling at you. I run and run past the pumpkin patch and the tractor rides. Look now, the sky is gold. I hug your legs and fall asleep on the way home."

3. 7

This is one of five ages mentioned in Mary's Song (Oh My My My) from Swift's self-titled debut album. This song tells the story of a guy and a girl going from young friends to an old couple, from the perspective of the girl. Swift was inspired to write this song by an elderly couple that lived next door.

The lyrics:

"She said, I was 7 and you were 9. I looked at you like the stars that shined in the sky. The pretty lights. And our daddies used to joke about the two of us, growing up and falling in love. And our mommas smiled, and rolled their eyes, and said 'Oh, my my my.'"

4. 9

This is the second of five ages in Mary's Song. It is mentioned directly after age 7 since it is the age of the guy in the song, who is two years older than the girl.

The lyrics:

"She said, I was 7 and you were 9. I looked at you like the stars that shined in the sky. The pretty lights."

5. 13

This goes back to The Best Day. Swift is no longer five, and she has new problems to deal with. Thankfully, her mom is by her side, like always. I was always able to relate to this part of the song, even before and since I turned 13.

The lyrics:

"I'm 13 now and don't know how my friends could be so mean. I come home crying, and you hold me tight, and grab the keys. And we drive and drive until we've found a town far enough away. And we talk and window shop 'til I've forgot all their names."

6. 15

You don't have to look hard to find this one. In fact, it's the name of the song. This song is also on Swift's Fearless album. It's about her beginning high school. She talks about friendship, love, and dreams. She even mentions the name of her real life best friend at the time, who she is still friends with now. Since it's the name of the song, 15 is mentioned multiple times.

The lyrics:

"'Cause when you're fifteen and somebody tells you they love you, you're gonna believe them. And when you're fifteen, feeling like there's nothing to figure out. Well, count to ten, take it in. This is life before you know who you're gonna be. Fifteen."

"When you're fifteen and your first kiss makes your head spin 'round. But in your life you'll do things greater than dating the boy on the football team. But I didn't know it at fifteen."

"When you're fifteen, don't forget to look before you fall. I've found time can heal most anything, and you just might find who you're supposed to be. I didn't who I was supposed to be at fifteen."

7. 16

We return to Mary's Song for this one. After the two young kids have grown up a little, their perspective on both life and each other changes. This is a turning point in their relationship. Remember, the song is told from the girl's perspective, so she's talking about her age.

The lyrics:

"Well, I was sixteen when, suddenly, I wasn't that little girl you used to see. But your eyes still shined like pretty lights. And our daddies used to joke about the two of us. They never believed we'd really fall in love. And our mommas smiled, and rolled their eyes, and said 'Oh, my my my.'"

8. 17

We jump forward a few albums for this one. The song Starlight on Swift's Red album tells the story of young Ethel and Bobby Kennedy. She saw a picture of Ethel and Bobby as teenagers, which inspired her to write a song about it. She actually played it for Ethel, who enjoyed it.

The lyrics:

"I met Bobby on the boardwalk, summer of '45. Picked me up late one night out the window. We were seventeen and crazy, running wild, wild. Can't remember what song it was playing when we walked in. The night we snuck into a yacht club party pretending to be a duchess and a prince."

9. 19

We skip over age 18 because apparently that's been done too many times for Taylor Swift to bother with it. 19, which happens to be the age of yours truly, is mentioned in Dear John, off of Swift's third album, Speak Now. This song is allegedly about Swift's relationship with John Mayer, which fits the timeline since she was 19 when they dated. I have always loved this song but felt a deeper connection to it when I turned 19.

The lyrics:

"Dear John, I see it all now, it was wrong. Don't you think nineteen's too young to be played by your dark, twisted games when I loved you so? I should've known."

10. 22

Certainly, everyone is familiar with this one. It is Swift's second song titled with an age and a popular anthem for people who are proud to be 22 and aren't afraid to dance like it. This is a song from the Red album, which came out shortly before Swift's 23 birthday.

The lyrics:

"I don't know about you, but I'm feeling 22. Everything will be alright if you keep me next to you. You don't know about me, but I'll bet you want to. Everything will be alright if we just keep dancing like we're 22."

11. 25

This age is mentioned in a song off Swift's most recent album, Reputation. As I subtly mentioned at the beginning, I'm not a fan of Taylor Swift's new music. For the sake of being thorough, though, I scanned Reputation for ages. I found 25 mentioned in the song Dancing With Our Hands Tied.

The lyrics:

"I, I loved you in secret. First sight, yeah, we love without reason. Oh, twenty-five years old. Oh, how were you to know?"

12. 87

We jump ahead quite a bit for this one! Obviously Taylor Swift isn't 87 yet, so she's not speaking from experience. At this point, you can probably guess which song this is from. If you thought Mary's Song, you're correct! This is at the end of the song, where the young friends are finally an old couple. The future tense implies that the couple this song is based on aren't quite that old. However, they intend on staying together until they are.

The lyrics:

"I'll be 87, you'll be 89. I'll still look at you like the stars that shine in the sky. Oh my, my, my."

13. 89

I could have combined 7 and 9, and 87 and 89 since they're so close together, but I wanted to make a point. If you've been paying attention to the numbers before the ages, you'll notice that this is the 13th age mentioned in a Taylor Swift song. If you're a Taylor Swift fan, you probably already know what that means. If not, let me enlighten you. 13 is Swift's lucky number. She was born on December 13 and turned 13 on Friday the 13. The number 13 is also connected to her music. Some of her songs have 13-second intros. Some of her albums have 13 songs. Some songs peaked at #13 on the Billboard Hot 100.

Could that fact that Taylor Swift mentions 13 different ages in her music be a coincidence? It could, but it seems unlikely. When it comes to Taylor Swift, there are hardly any coincidences. Since she has been using ages in songs since her first album, it is likely she will mention more on subsequent albums. However, she has never gone less than four years in-between albums, so this 13 reference will stick around for quite some time.
