Frequently Asked Questions
How do I calculate my age from date of birth?
Subtract your birth year from the current year, then adjust by whether your birthday has passed this year. This calculator does it automatically down to the minute.
How do I calculate age in months?
Multiply completed years by 12, then add the number of full months since your last birthday. A 25-year-old born in March (today is October) is 307 months old.
What's my age in days?
For most adults it's between 7,000 and 25,000 days. A 30-year-old is about 10,950 days old. This tool computes the exact figure for you.
Does this handle leap years?
Yes. The calculator uses native date arithmetic so February 29 birthdays and leap-year day counts are handled correctly.
