Calculate your exact age in years, months, days, hours, and minutes — plus your next birthday countdown and zodiac sign.
An Age Calculator is a free online tool that calculates your exact age from your date of birth. Unlike a simple year difference, it provides a precise breakdown in years, months, days, hours, minutes, and total weeks. It also shows the day of the week you were born, your zodiac sign, and the number of days until your next birthday. It is useful for forms, legal documents, visa applications, or satisfying your curiosity.
Age is calculated by finding the difference between today's date and your date of birth. The tool accounts for leap years and varying month lengths to provide an exact breakdown in years, months, and days.
Chronological age is the actual time elapsed since you were born, which is what this calculator measures. Biological age reflects how old your body appears based on health markers and can differ from chronological age.
