You know your age. Obviously. But do you know how many days you’ve been alive? How many hours? When’s your next birthday in exact days? This calculator is about to make you feel ancient or surprisingly young, depending on how you look at it.

What it does: Takes your birth date and calculates your exact age in years, months, days, weeks, hours. Everything. It’s like that friend who’s too detailed but you secretly appreciate them.

How to actually use it:

Open the calculator. You’ll see one field asking for your date of birth. Pick your birthday. If you’re one of those people who lie about their age, now’s your chance to come clean, at least to yourself. Hit “Calculate My Age.”

Watch the magic happen. Three big boxes pop up showing your age in years, months, and days. Below that, you get the extra sauce. Total months you’ve existed. Total weeks. Total days. Total hours. Then, because the calculator really wants you to plan ahead, it tells you exactly how many days until your next birthday.

When this becomes useful:

That visa application asking for your exact age in years and months? You're covered. Your friend's betting you can't be 25 because you still watch cartoons? Show them the receipts. You're wondering if you've lived 10,000 days yet (spoiler: if you're over 27, you have)? Check it.

Here's the thing: Age is just a number until you see it broken down into 292,000+ hours. Then it hits different. You start wondering what you did with all that time. Did you really spend 600 hours arguing on Twitter? Probably. Was it worth it? Also probably.

The interface is clean. No confusing buttons. No signing up. Just you, your birthday, and the cold hard facts about how long you've been on this Earth dealing with Nigeria's economy.
