Years are estimated from elapsed days divided by 365.2425, rather than an exact birthday-based legal age.
Read KitNelo data and privacy detailsChoose a birth date and view the elapsed-day result together with its approximate year estimate. Check the date carefully; the estimate uses an average year length rather than counting completed birthdays.
Enter the birth date to see the number of days elapsed since that date. Review the selected day, month and year before copying the figure into a personal record or informal milestone calculation.
Use a birth date to obtain an age estimate calculated from elapsed days divided by 365.2425. Treat the year value as approximate; verify completed birthdays separately when a form or rule requires an exact age.
