Age Calculator
Exact age or the gap between two dates — years, months, days, totals, day born, and next birthday.
How to use
Pick a birth or start date and an end date (defaults to today) — the exact gap in years, months, and days updates live, plus totals in months, weeks, days, and hours. When the start is a birthday it also shows the day of the week you were born and a countdown to your next birthday. Order doesn't matter; it always shows a positive span.
