Calculators
Calculate your exact age in years, months, days, hours, and minutes from a birthdate. Also shows next birthday countdown and day-of-week for any historical date.
Follow these simple steps to get instant, accurate results directly in your browser:
Choose your birth year, month, and day using the calendar dropdowns.
Leave set to today, or select a specific past or future date to compute age at that point.
View your exact age in years, months, and days, plus days remaining until your next birthday.
The Age Calculator calculates a person's exact chronological age down to years, months, weeks, days, hours, minutes, and seconds based on their date of birth.
The calculator accounts for leap years, variable calendar month lengths, and the current local clock time. It also reports upcoming birthday milestones, day of the week of birth (e.g. born on a Tuesday), and total lifetime statistics (such as total breaths taken and heartbeats estimated).
All date arithmetic executes locally in your web browser. Your personal birth dates and milestone details remain strictly private.
Age Years = Current Year - Birth Year (adjusted if current month/day precedes birth month/day)Calculates completed years, borrowing days from preceding calendar months when calculating month and day remainders.
Birth Date: September 15, 1995 | Current Date: September 5, 2026 Year Difference: 2026 - 1995 = 31 years Because September 5 precedes September 15, borrow 1 month from August (31 days): Completed Age = 30 Years, 11 Months, and 21 Days.
