Calculator
Exact age with a live countdown to your next birthday.
Life expectancy is set to 82 years for visualisation.
Guide
The calculator measures the exact time between your date of birth and the current moment, then breaks that span into years, months and days. It also locates your next birthday and plots life expectancy progress so you can see where you stand.
Subtract the birth date from today. If the current month/day is before your birthday, borrow a month and the matching number of days from the previous month to keep the values positive. That yields the familiar Y/M/D breakdown we show in the UI.
We compute the next birthday and milestones like 40 and 65 by adding fixed year offsets to your birth date. The progress bars compare days lived to the days required to reach each milestone, giving a quick glance at how close you are.
Precise age is required for passports, medical screenings, benefits eligibility and planning for retirement or schooling. Seeing the countdown encourages proactive planning rather than reacting when deadlines appear.
