Use this free age counter to see exactly how old you are in years, months, and days. It doubles as a day counter for your life, with totals in weeks, days, and hours, plus a countdown to your next birthday.
Your dates stay in your browser — nothing is uploaded.
This free age calculator works like a counter for the time between your date of birth and any date you choose. By default it uses today, so you get your current age right away, but you can set the second date to the past or future to see how old you were, or will be, on a particular day. Many people use it as a simple age counter for birthdays, anniversaries, and milestones.
The result is shown the way people normally say it — full years, then the leftover months, then the leftover days — using the real length of each calendar month. Leap years are handled automatically because the math is based on actual dates, not a fixed 30 or 365 day approximation. Below that you also get the totals some people prefer: how many months, weeks, days, and hours old you are, plus how many days are left until your next birthday.
