Enter your date of birth and our calculator instantly shows your exact age in years, months, days, hours, and minutes — calculated to the present moment. It also shows your next birthday and how many days remain. The calculation accounts for leap years and varying month lengths automatically.
Your age in years is the number of complete years between your date of birth and today. If you were born on 15 March 1990 and today is 1 August 2026, you are 36 years old — because your 37th birthday on 15 March 2027 has not arrived yet. The months and days shown represent progress through your current year of life.
If you were born on 29 February (a date that only exists in leap years), most legal systems observe your birthday on 28 February in non-leap years. Our calculator handles this correctly.
In many legal and administrative contexts, your age on a specific date determines your eligibility for benefits, services, or requirements. Retirement age calculations, school enrollment cutoffs, age-restricted purchases, and voting eligibility all depend on precise age determination. Our calculator uses the standard international method where age increases on the anniversary of your birth date, accounting for leap years automatically.
Age calculators are useful for genealogical research, verifying historical records, and calculating how old historical figures were at key events. Enter a birth date from any year and a past date to calculate the age at that point in history. This is helpful for verifying census records, military service eligibility, and marriage records where a person's age is stated but needs verification against a known birth date.
