Your age is the exact calendar span from your date of birth to the chosen date. The tool finds the largest whole number of months between the two dates (clamping month-ends, so 31 Jan + 1 month = 28/29 Feb), then the remaining days. Totals in weeks, days, hours, minutes and seconds come from the exact day count, so every leap day is counted.
