If you were born in 1987, you will be turning 36 years old in 2023. But here’s the thing: your exact age depends on whether your birthday has already passed this year. Before your birthday, you’re still 35.
On or after your birthday, you hit 36.
I’ll show you how to calculate this for yourself and for any other year. It’s a common question people search for when they need to remember their own age, a friend’s age, or just for filling out forms.
We’ll cover the simple math, the important ‘birthday rule,’ and some interesting facts about the year 1987. Trust me, it’s easier than you think.
The Simple Math: Calculating Your Age from 1987
Calculating your age is a no-brainer, and just use this simple formula:
Current Year – Birth Year = Age
Let’s apply it to the keyword: 2023 – 1987 = 36. This means if you were born in 1987, you’ll turn 36 on your birthday in 2023.
I was talking to a friend the other day, and they said, “I always forget how old I am until I do the math.” It’s a common feeling. But with this formula, you can quickly figure it out.
For another example, let’s calculate the age for someone born in 1992 in 2023: 2023 – 1992 = 31. So, if you were born in 1992, you’ll be 31 this year.
This method is the fastest way to get a definitive answer for the age someone will turn in a given year. No need to overthink it.
| Birth Year | Current Year | Age |
|---|---|---|
| 1987 | 2023 | 36 |
| 1992 | 2023 | 31 |
Remember, Current Year – Birth Year = Age. It’s that simple.
The ‘Birthday Rule’: Why Your Exact Age Might Be Different
You might think age is a straightforward number, but it can get a little tricky. Especially when you’re in the middle of a calendar year.
If your 2023 birthday has already passed, you are 36 years old. Simple enough, right?
But if your 2023 birthday hasn’t happened yet, you’re still 35 years old.
Imagine someone with a birthday in November 2023. They’re 35 from January through October, and then, in November, they turn 36.
This is why you might hear people say, “I’m 35, but I’ll be 36 in November.” It’s like that scene in The Big Lebowski where Walter says, “Yeah, well, you know, that’s just, like, your opinion, man.”
So, if you were born in 1987, the basic subtraction formula (2023 – 1987) always gives you the age you will be at the end of the year, after your birthday has passed. 1987 age in 2023
A Snapshot of 1987: Your Birth Year in History

If you were born in 1987, you’re part of the Millennial generation. We’re known for being tech-savvy and value-driven, always looking for ways to make a difference.
But let’s be real. Sometimes, it feels like we’re stuck between two worlds. The analog world of our parents and the digital world that’s all around us now.
It can be frustrating.
In 1987, a lot was happening. “The Simpsons” made its debut on The Tracey Ullman Show. It’s amazing how that show has been around for so long.
Then there was the “Black Monday” stock market crash. That one still gives people chills. And, of course, the signing of the Intermediate-Range Nuclear Forces Treaty.
Big stuff, right?
You know who else was born in 1987? Lionel Messi, Blake Lively, and Kendrick Lamar. It’s kind of cool to share a birth year with such big names.
At 36 years old in 2023, it’s easy to feel like time is flying by. But looking back at 1987, it’s clear that it was a year full of significant events.
So, next time someone asks about your birth year, you can drop some serious knowledge. Trust me, it’s a conversation starter.
Beyond 2023: A Timeless Formula for Calculating Your Age
Transitioning from a specific query to a universally useful tool, let’s empower you with a simple method to calculate your age for any year.
Step 1: Choose the Target Year (e.g., 2030).
Step 2: Subtract the Birth Year (e.g., 1987). The result (43) is the age they will turn in that year.
Step 3: Remember to apply the ‘Birthday Rule’—subtract one if the birthday hasn’t passed in the target year.
Here’s a small, easy-to-read table to show how this works:
| Target Year | Age for Someone Born in 1987 |
|---|---|
| 2025 | 38 |
| 2030 | 43 |
| 2035 | 48 |
This formula is incredibly handy for planning and understanding your age in future years.
1987 age in 2023 is 36, demonstrating the formula’s practicality.


Cathleena Camachora has opinions about digital infrastructure strategies. Informed ones, backed by real experience — but opinions nonetheless, and they doesn't try to disguise them as neutral observation. They thinks a lot of what gets written about Digital Infrastructure Strategies, Expert Breakdowns, Tech Workflow Optimization Tips is either too cautious to be useful or too confident to be credible, and they's work tends to sit deliberately in the space between those two failure modes.
Reading Cathleena's pieces, you get the sense of someone who has thought about this stuff seriously and arrived at actual conclusions — not just collected a range of perspectives and declined to pick one. That can be uncomfortable when they lands on something you disagree with. It's also why the writing is worth engaging with. Cathleena isn't interested in telling people what they want to hear. They is interested in telling them what they actually thinks, with enough reasoning behind it that you can push back if you want to. That kind of intellectual honesty is rarer than it should be.
What Cathleena is best at is the moment when a familiar topic reveals something unexpected — when the conventional wisdom turns out to be slightly off, or when a small shift in framing changes everything. They finds those moments consistently, which is why they's work tends to generate real discussion rather than just passive agreement.
