Interesting Facts
How It Works
Your age is calculated by comparing your birth date to the reference date using calendar-aware logic. The calculator accounts for different month lengths, leap years, and century rules to provide the most accurate result possible.
Frequently Asked Questions
How accurate is the age calculation?
Your age is calculated to the exact day using calendar-aware arithmetic that accounts for month lengths and leap years. All time values (hours, minutes, seconds) are derived from the total days lived.
Why is my age different from other calculators?
Some calculators use simplified 365-day years or 30-day months. Our calculator uses the actual calendar for precise results on any date.
How is my next birthday calculated?
By adding your current age + 1 to your birth date. If your birthday falls on February 29, we use February 28 in non-leap years.
What does the 90-year reference mean?
It is an illustrative reference span that puts current age on a simple percentage scale. It is not a universal lifespan, a statistical life-expectancy claim, or a prediction about any person.
Can I calculate someone else's age?
Yes. Enter any date of birth and reference date — the calculator works for yourself, family members, or historical figures.
How are leap year birthdays handled?
If born on February 29, your birthday is correctly handled. February 28 is used in non-leap years.
