How It Works
How is age calculated? ▾
Age is calculated by finding the difference between your date of birth and today's date (or the custom date you choose). The result shows exact years, months, and days — accounting for leap years and varying month lengths.
What is a leap year and how does it affect age? ▾
A leap year has 366 days instead of 365, occurring every 4 years (e.g., 2000, 2004, 2024). If you were born on February 29, your birthday technically falls on March 1 in non-leap years, and the calculator handles this correctly.
How is the Zodiac sign determined? ▾
The Western zodiac sign is based on the Sun's position on your birth date. There are 12 signs, each covering about 30 days of the year — from Aries (Mar 21) to Pisces (Feb 19). This calculator shows your sign based on your birth month and day.
What is a generation? ▾
Generations are groups of people born in the same era, sharing cultural experiences. Examples: Silent Generation (1928–1945), Baby Boomers (1946–1964), Gen X (1965–1980), Millennials (1981–1996), Gen Z (1997–2012), Gen Alpha (2013–present).
