Why use this age calculator & birthday countdown?
Calculating age seems simple until accounting for leap years, differing month lengths (28, 30, 31 days), and daylight savings shifts. This tool performs Gregorian calendar arithmetic to accurately compute the precise span of time between any two dates without off-by-one errors.
