If I Was Born 1998 How Old Am I

How Old Am I If I Was Born in 1998?

The short answer? Sounds simple, and it kind of is. But the slightly longer answer — the one that actually matters — depends on whether your birthday has already passed this year. It depends on when you're asking. But people get confused because age isn't just "the year you were born subtracted from the current year." If it were, you'd be off by one every time your birthday hasn't happened yet.

So let's break this down properly.

The Quick Math

If today falls after your birthday in 1998, you're currently 27 years old. If today falls before your birthday, you're still 26.

That's the whole trick. Two possible answers, and which one is right depends on one thing: has your birthday already happened this calendar year?

Here's an example. Say you were born on March 15, 1998, and it's currently October. Here's the thing — your birthday has passed, so you're 27. Consider this: easy. But if today is February 10, 2026, and your birthday is March 15, 1998, you haven't turned 27 yet. You're still 26. The year is 2026, but your age doesn't care about the year — it cares about the date.

This is the bit that trips people up the most.

The Korean Age Thing

If you're from South Korea or grew up around Korean culture, you might have heard someone say they're "29" even though they were born in 1998. That's Korean age, and it works completely differently. In the Korean age system, you're 1 at birth, and you gain a year every January 1st regardless of your actual birthday.

So someone born December 31, 1998 would be 1 year old at birth, 2 on January 1, 1999, and would tick up every January 1 after that. By 2026, they'd be 29 in Korean age even if their international age is 27 (or 26, depending on the date).

South Korea officially stopped using Korean age for most legal and administrative purposes in 2023, switching to the international standard. But the old system still shows up in casual conversation, especially among older generations or in certain cultural contexts. So if someone tells you they're 29 and was born in 1998, they're probably using the old system — not inflating their age for fun.

What About Chinese Age or East Asian Age Systems?

Similar idea to Korean age, but slightly different. In the traditional Chinese system, you also start at 1 at birth, and gain a year at the lunar new year rather than January 1. Still, in practice, most Chinese people today use the international age system day-to-day. The traditional version mostly shows up in family contexts, fortune-telling, and a handful of traditional customs.

Worth knowing the difference exists. Not worth losing sleep over unless you're filling out paperwork in another country.

Why People Actually Ask This Question

Honestly, the math isn't hard. So why does this question get searched thousands of times a year? A few reasons come to mind.

Job applications and age cutoffs. Lots of job listings have age preferences, especially in countries where it's legal to ask. A company looking for someone "25–30" might get a flood of applicants born in 1998 trying to figure out where they land. And yeah, it matters whether your birthday has passed.

Insurance and financial products. Some products have age brackets. A "27-year-old" rate might be meaningfully different from a "26-year-old" rate. Insurance companies don't round up out of kindness.

Curiosity about generational labels. Born in 1998? You're usually pegged as the tail end of Gen Z (though some sources put the cutoff at 2000, others at 1997). The exact micro-bracket varies depending on who's defining it. Pew Research, for instance, has placed Gen Z as starting in 1997 in some of their work. So depending on the source, you might be the youngest millennials or the oldest zoomers. Welcome to the identity crisis.

Legal stuff. Voting age, drinking age, renting a car, signing certain contracts — all depend on your exact age down to the day. Some countries and contexts take this very seriously.

Just wanting to know. Not every question needs a deep reason. Sometimes you're filling out a form and your brain blanks. That's fine too.

Age Milestones If You Were Born in 1998

Just for reference, here's a quick mental map of where you are right now and what's coming up.

• You turned 18 in 2016 — legal adult in most countries.
• You turned 21 in 2019 — drinking age in the US, though you could vote and drive years earlier.
• You turned 25 in 2023 — used to matter a lot for car rental; rates often drop at 25.
• You turned 27 in 2025 (if your birthday has passed) — this is the current international age for most 1998 babies as of early 2026.
• You'll turn 28 in 2026 — assuming your birthday hasn't come yet.
• You'll turn 30 in 2028 — the big three-oh. Plenty of time to panic.

So depending on the exact date you're reading this, you're either 26 or 27, and you've got about two years until the next round-number birthday.

Common Mistakes People Make With This Calculation

The first mistake is the obvious one: just subtracting. Someone born in late 1998 doing "2026 minus 1998" gets 28, which is wrong if their birthday hasn't passed. It's a year-off error, and it happens more than you'd think.

The second mistake is forgetting about time zones and date lines. If you're born in 1998 in one country and asking the question from another, the date difference is almost always irrelevant. But if it's right on the edge of midnight somewhere, things can get weird. Don't overthink it.

The third mistake is mixing up calendar systems. Someone hears "you turn a year older at the lunar new year" and applies that to their own age calculation. Now, if you were born in 1998 and you're using the international system, your birthday is your birthday. Lunar new year doesn't change it.

Practical Tips for When You Need to Know Your Exact Age

If you need a precise answer — say, for a legal document or a medical form — don't do the mental math. Use your ID. Now, that's the source of truth. Your driver's license, passport, or government ID has your date of birth. The age on that document is your official age, and that's what institutions care about.

If you're filling out an online form that asks your age and not your date of birth, just count the years from your birth year to the current year, and then subtract one if your birthday hasn't happened yet. Takes about three seconds once you've done it a few times.

For job applications that ask "year of birth" instead of age, you don't have to do any math at all. Just put 1998. They can do the subtraction themselves.
