Calculate Your Age by Date of Birth.

To calculate your age, subtract your date of birth from today's date. For example, if you were born on August 26, 1995, and today is August 26, 2025, you are exactly 30 years old. For a more precise result — including months, days, hours, and live seconds — use our free Age Calculator by Date of Birth above. Just enter your DOB and hit Calculate!

Age is calculated by comparing your date of birth (DOB) to a reference date (usually today). The standard method used internationally (ISO-8601) subtracts the birth year, month, and day from the current date, accounting for whether the birthday has passed this year. Our tool handles all edge cases including leap years and timezone differences automatically.

Human age is calculated from the date of birth to the current date using the Gregorian calendar. The formula counts complete years, then remaining months, then remaining days. For example: Born January 1, 1990 — as of January 15, 2025, you are 35 years, 0 months, and 14 days old. Our age calculator does this instantly and also shows hours, minutes, and live seconds.

Body age (also called biological age) refers to how old your body functions relative to your chronological age. While our tool calculates your exact chronological age from your date of birth, body age depends on factors like fitness level, diet, sleep, and lifestyle. Your chronological age is a starting point — use our calculator to know your exact age, then consult a health professional for body age assessment.

To calculate age by DOB (Date of Birth): (1) Note your date of birth — e.g., 15 March 1998. (2) Note today's date — e.g., 26 August 2025. (3) Subtract: 2025 - 1998 = 27 years. Then check if the birthday (March 15) has passed in 2025 — yes, so the age is 27 years, 5 months, and 11 days. Use our online age calculator by DOB at the top of this page for instant, precise results.

A person born in 2007 would be 17 or 18 years old in 2025, depending on whether their birthday has already occurred in 2025. For example: if born on January 1, 2007, they turn 18 on January 1, 2025. If born on December 31, 2007, they are still 17 years old until December 31, 2025. Use our age calculator to get the exact age including months and days for any 2007 birth date.

A quick mental math trick to calculate age: Take the current year (e.g., 2025), subtract the birth year (e.g., 1995) = 30. Then check if the person's birthday has occurred this year — if not, subtract 1. So someone born in October 1995 would still be 29 in August 2025.

Instead of multiplying by 7, modern veterinary standards (AVMA & AAHA) calculate that a dog's first year equals approximately 15 human years, their second year adds 9 years (making a 2-year-old dog 24 human years old), and each subsequent year adds 4 to 7 years depending on whether the dog is a small, medium, large, or giant breed.

Veterinarians divide pet life into four distinct phases: (1) Puppy/Kitten/Juvenile (rapid growth & immunity), (2) Young Adult (peak vitality & social maturity), (3) Mature Adult (stable prime companion years), and (4) Senior/Geriatric (specialized joint, organ, and dietary care).

Cats age very similarly to small dogs: by age 1, a cat is roughly 15 human years old; by age 2, they reach 24 human years. Each additional calendar year adds approximately 4 human years. A 10-year-old indoor cat is about 56 human years old.
