Frequently Asked Questions (FAQ)

Q: How does the age calculator work?
A: The calculator uses the difference between the two dates you provide. It calculates the total number of years, then the remaining months, and finally the remaining days to give you a precise breakdown.

Q: Does this calculator account for leap years?
A: Yes! Our algorithm correctly factors in leap years, ensuring the day count is always accurate.

Q: What date format should I use?
A: You can use the calendar picker or enter the date in the DD/MM/YYYY format (e.g., 25/12/1990). The calculator will automatically understand it.

Q: Can I calculate age for a future date?
A: Absolutely. If you set the “Age At The Date Of” field to a future date, the calculator will tell you how old you will be on that specific date.

Q: Why are there different results for months and weeks?
A: A month is not a fixed number of days (they vary from 28 to 31), and a year is not an exact number of weeks (52 weeks + 1 day, or +2 in a leap year). The “years, months, days” result is the most accurate reflection of your calendar age.
