Calculate your exact age in years, months, and days. Find your next birthday and total days lived with our precise age calculator
Enter your date of birth to calculate your exact age
Our precise age calculator determines your exact age in years, months, and days from your date of birth. It also shows how many total days you've been alive and counts down to your next birthday, making it perfect for age verification, planning celebrations, or simple curiosity about your life timeline.
Using the calculator is straightforward: simply enter your date of birth using the calendar picker, and click Calculate Age. The tool instantly provides comprehensive age information including years, months, days, total days lived, and days remaining until your next birthday. The calculation accounts for leap years and varying month lengths for complete accuracy.
This tool is useful for many purposes including filling out forms that require precise age, planning age-milestone celebrations, calculating age eligibility for various programs, tracking developmental milestones for children, and satisfying curiosity about exactly how long you've been alive. It's also helpful for calculating age differences between people or determining someone's age on a specific future date.
Age calculation might seem simple, but accurately accounting for varying month lengths and leap years requires careful computation. Our calculator uses precise date arithmetic to ensure accuracy.
Example: If today is January 15, 2024, and date of birth is March 25, 1995:
Initial calculation: 2024 - 1995 = 29 years, 1 - 3 = -2 months, 15 - 25 = -10 days
After adjustment: 28 years, 9 months, 21 days
The calculator also computes total days lived by calculating the difference between birth date and current date in milliseconds, then converting to days. For the next birthday countdown, it determines when your next birthday occurs and calculates days remaining. These precise calculations ensure you always get accurate age information regardless of leap years or month variations.
Understanding age milestones helps in planning life events and understanding developmental stages. Here are some significant age markers across different cultures and contexts.

Manual age calculations often miss accounting for varying month lengths (28-31 days) and leap years. Our calculator uses precise date arithmetic that considers all calendar variations, ensuring your age is calculated down to the exact day with complete accuracy.
The calculator automatically accounts for leap years when calculating your age. If you were born on February 29 (leap day), the calculator considers February 28 as your birthday in non-leap years when calculating age and next birthday countdown.
Yes, you can enter any date of birth to calculate that person's current age. While this version calculates age as of today, the same principles apply. You can manually calculate age at a specific past or future date by knowing the target date.
Chronological age (what this calculator shows) is your age in years since birth. Biological age refers to how old your body appears based on health markers and can be younger or older than chronological age depending on lifestyle, genetics, and health habits.
Exact age is crucial for legal documents, age-restricted services, eligibility verification for programs, academic admissions, pension calculations, insurance policies, and medical records. Many official processes require precise age in years, months, and sometimes days.
