🎂 Age Calculator
Calculate your exact age in years, months, days, hours and minutes — or find the age between any two dates.
Years, Months & Days
Age is calculated by finding the exact difference between your date of birth and today (or a chosen date). The calculator accounts for leap years and varying month lengths to give a precise result.
Age Between Two Dates
Change the "Age at Date" field to any past or future date. This is useful for calculating how old someone was on a specific date, or for planning future milestones like retirement or anniversaries.
Total Days, Hours & Minutes
The calculator converts your full age into total days (including leap years), total hours (days × 24), and total minutes (hours × 60) — great for milestone celebrations.
Age is calculated by finding the difference between your birth date and the current date (or a chosen date), broken down into years, months, and days. Leap years and varying month lengths are accounted for.

The days remaining until your next birthday are calculated by finding the next occurrence of your birth month and day from today's date. If today is your birthday, it shows 0 days!
Our calculator shows the day of the week you were born using the Gregorian calendar, which is accurate for all modern dates.
