How to Calculate Age Manually
While our tool automates the process, understanding the manual calculation can be helpful. To calculate age manually:
- Subtract the birth year from the current year

- For months, count the full months between dates
- For days, calculate the remaining days after years and months
Our calculator handles all these complexities automatically, including leap years and varying month lengths.
Frequently Asked Questions About Age Calculation
How does the age calculator account for leap years?
Our algorithm automatically accounts for leap years by checking if February 29th falls between the date range and adjusting the day count accordingly.
Can I calculate age at a specific past or future date?
Yes! Use the "Age at This Date" field to calculate how old someone was or will be on any specific date.
Why do months show varying results in age calculation?
Months have different lengths (28-31 days). Our calculator accounts for these variations by comparing the specific calendar dates rather than using average month lengths.
Can I calculate my age in weeks?
Yes, our results include total weeks alongside years, months, and days for comprehensive age tracking.
Is this age calculator accurate for historical dates?
Our calculator uses the Gregorian calendar system and is accurate for dates from the 16th century onward. For earlier dates, calendar system differences may affect results.
