How to calculate your age
Enter your date of birth and the date on which you want to calculate your age. Leave the second field on today for your current age, or choose a past or future date for a historical or planned age.
How does the Age Calculator work?
WCODX compares calendar dates and accounts for different month lengths and leap years. It treats each input as a date, not as a timestamp, so the selected day remains stable across time zones.
Calculate age in years, months and days
Exact calendar age cannot be found reliably by dividing total days by 365. The calculator first counts complete calendar years and months, then the remaining days, including month-end and leap-year cases.
How many days old am I?
The age summary includes total whole calendar days between the two dates. Weeks, hours and minutes are derived from those days and are useful estimates because no birth time was entered.
Calculate age on a specific date
Use the Calculate Age On field to answer questions such as how old you were on a past date or how old you will be on a future date. The selected target date does not depend on your device's current date.
Leap years and birthdays
February 29 birthdays are calculated using valid calendar dates. For the next-birthday display only, WCODX uses February 28 in non-leap years, while historical age arithmetic remains calendar-accurate.
Age Calculator FAQ
How old am I today?
Enter your date of birth and leave the calculation date set to today. The calculator uses your browser's local date and shows your calendar age.
How is exact age calculated?
WCODX compares calendar years, months and days rather than dividing the number of days by 365. This accounts for different month lengths and leap years.
Can I calculate my age on a future date?
Yes. Select any valid future calculation date to see how old you will be on that date.
Can I calculate how old I was on a past date?
Yes. Select a past date after your birth date to calculate your historical age.
How does the calculator handle leap years?
The calculation uses calendar arithmetic and validates leap years. For a February 29 birthday, the next birthday is shown as February 28 in non-leap years.
What happens if I was born on February 29?
Your historical age remains calendar-accurate. For the next-birthday countdown, WCODX uses February 28 in non-leap years as its consistent convention.
How many days old am I?
The age summary shows the whole calendar days between your date of birth and the selected calculation date, followed by derived weeks, hours and minutes.
Does WCODX store my date of birth?
No. The calculation is performed locally in your browser. Your dates are not sent to or stored by WCODX.
