Here are five top terms from our list that you can use to talk about that person who shares this fun coincidence with you.
Birthday Twin
Your “birthday twin” is someone born on the exact same day as you. This term suggests shared celebrations and mutual good wishes.
While other names or phrases that describe someone who shares your birthday might have astrological or more flexible meanings, “birthday twin” is a straightforward way to refer to such a person.
So, if you bump into each other at a party and find out you share a birthday, you’ve just met your birthday twin!

Time Twins
“Time twins” takes the shared birthday idea a step further. It’s used for people born on the exact same date, year, and time. The term points out a special synchronicity: your lives started at the exact same second.
The focus on “time” makes this term different from ones that are more about the date. It’s a specialized term used less often, adding its own unique touch to your shared birthday story.
Check out the examples below for the use of the term in sentences:
- “We’re not just born on the same day, but at the same time. We’re time twins!”

- “You were born at 9:15 AM too? That makes us time twins.”

Astro Twin
An “astro twin,” or “astrological twin,” is someone who not only shares your birthday but was also born in the same year. This makes their astrological sign and birth chart almost the same as yours.
This term goes beyond just the date to look at the astrological meaning of your shared birthday, adding a cosmic twist.
An astro twin has a very specific celebratory significance. Astro twins might believe or find they have a lot in common, like personality traits, likes, and dislikes.
Given below are example sentences using the term astro twin:
- “My astro twin and I have similar personalities, which isn’t surprising given our shared astrology.”
- “Meeting my astro twin and seeing how similar we were made me believe more in astrology.”
- “Having an astro twin means sharing a cosmic connection.”
- “My astro twin and I always discuss about our shared star sign traits.”
Star Twin
Your “star twin” is someone who shares your birthday, with a focus on the stars or planets’ positions when you both were born. It’s similar to “astro twin” but broader, not needing as close a match in astrological charts.
“Star twin” has a sense of awe, appealing to those who like to think of their connections as part of a bigger celestial pattern. What sets it apart is the suggestion of a shared fate or cosmic bond, which offers a less personal but more whimsical reason to celebrate together.
Consider the examples below to see the term used in sentences:
- “We’re star twins, born under the same celestial configuration.”
- “I truly believe that my star twin and I have a special bond.”
- “It’s fascinating to compare life experiences with my star twin.”
- “My star twin and I were both born when the constellation Orion was visible.”
Birthday Buddy
The idea of a “birthday buddy” shows a fun connection between people, whether they’re friends, classmates, coworkers, or even strangers. The word “buddy” suggests a friendly and less formal relationship compared to “twin.” This is perfect for situations where you want to celebrate the coincidence with someone who isn’t necessarily your same age.
“Birthday buddy” highlights the shared experience and often sparks a sudden sense of friendship at a birthday party, unlike other terms, which might suggest a deeper or more formal connection.
Having a birthday buddy can make your own birthday feel even more special, as it gives you a chance to share the fun and double the celebration with someone else.
Look at the following examples to understand how the term is used in sentences:
- “My birthday buddy and I always throw a joint party.”
