Frequently Asked Questions (FAQ)
How is age calculated?
Age is calculated by subtracting the birth date from the current date. Our age calculator accounts for leap years, varying month lengths, and provides results in years, months, days, hours, minutes, and seconds for maximum precision.
What is the most accurate way to calculate age?
The most accurate age calculation includes the exact time of birth and current time, accounting for time zones and daylight saving time. Our calculator provides precise results down to the second.
How do you calculate age in months?
Age in months is calculated by counting the number of full months that have passed since birth. Our calculator shows both years and months for a complete age representation.
What age is considered a senior citizen?
Senior citizen status varies by country and context. Generally, age 65 is considered senior citizen status in many countries for retirement benefits, while some programs consider age 60 or 62.
How do leap years affect age calculation?
Leap years add an extra day (February 29) every 4 years. People born on February 29 only have actual birthdays every 4 years, but our calculator accurately tracks their age in non-leap years.

Chronological age is the actual time since birth (what our calculator shows). Biological age refers to how old a person's body appears based on health, lifestyle, and genetics.

Legal ages vary: 18 for voting and military service, 21 for alcohol in the US, 16 for driving in many places, 13 for social media. Always check local laws as they vary by jurisdiction.
