Understanding Age Calculations

Leap year considerations: Age calculations account for leap years occurring every 4 years, with exceptions for century years not divisible by 400. This ensures accurate day counts over long periods.

Time zone factors: Age calculations use the selected date without time zone adjustments, focusing on calendar dates rather than precise time differences.

Cultural age counting: Different cultures calculate age differently - some count time in the womb, others start from birth, and some use lunar calendars instead of solar years.
