26 years, 0 months, and 0 days — happy birthday! 🎉
Today is your birthday.
How your age is calculated
Your age is the time elapsed from your date of birth to today (or any date you choose in the second field). The calculator works it out as full years first, then the remaining whole months, then the leftover days — the same way ages are stated in everyday life.
Age in months, weeks, and days
Below the main figure you also get your age expressed entirely in months, in weeks, and in days, which is handy for baby milestones, anniversaries, or quick comparisons.
Leap-day birthdays
If you were born on February 29, your birthday only occurs in leap years. In other years this tool treats February 28 as the birthday for the countdown, which is the most common convention.
Frequently asked questions
- Can I calculate my age on a past or future date? Yes — change the “Age at date” field to any date on or after your birth date.
- Is my date of birth stored anywhere? No. It stays in your browser and is never sent to a server.
