Age Calculator — Calculate Exact Age in Years, Months & Days
Free online age calculator. Enter your date of birth and instantly see your exact age, total days lived and a countdown to your next birthday.
Skycally's Age Calculator gives you a precise breakdown of your age the moment you enter your date of birth. Instead of just a year count, you get years, months and days — the same way a doctor or official document would describe an age — plus useful totals like the number of days, weeks, hours and minutes you've been alive.
It also tells you exactly when your next birthday falls and how many days are left until then, which makes it handy for planning, gifts, paperwork, or just a bit of fun. The calculation accounts for varying month lengths and leap years, so the result is always accurate.
Everything is computed in your browser. Your date of birth is never sent to a server, never stored and never logged. Use it for yourself, your kids, friends or any historical figure whose birth date you're curious about.
Frequently Asked Questions
How is the exact age calculated?
We compare year, month and day separately, borrowing from the next-larger unit when needed. This matches how official documents and doctors describe a person's age.
Does it handle leap years?
Yes. The calculation uses real calendar dates, so leap years and varying month lengths are accounted for automatically.
Can I calculate someone else's age?
Yes. Just enter their date of birth — the tool works for anyone, living or historical.
Is my data saved?
No. The date of birth stays in your browser and is cleared when you close the tab.
