Your exact age in years, months and days — plus how many days you have lived and when your next birthday lands.
The calculator takes your date of birth and today's date and works out the complete years first, then the complete months, then the leftover days — exactly the way official forms ask for age. It also converts your whole life into fun totals: days, weeks and hours lived, and counts down to your next birthday (including the milestone of your next "round" day, like day 10,000).
Full years first, then full months, then remaining days, comparing your birth date with today — the same method used on official forms.
Your result includes total days lived, plus totals in weeks and hours — fun for milestones like your 10,000th day.
The result shows the date of your next birthday and the exact number of days until it. If today is your birthday — happy birthday!
Leap-day birthdays are handled correctly; in non-leap years the next-birthday countdown treats 1 March as your birthday, the most common convention.
