What This Calculator Does
The Age Calculator converts a date of birth into years, months, and days. It also shows total days lived, zodiac sign, and how many days until your next birthday.
How It Works
The calculator uses UTC date math to count exact years, months, and days between your birth date and today. Zodiac sign is determined from birth month and day.
Example
Someone born on June 15, 2000 is exactly 26 years old with 3 months and 5 days. Total days lived: about 9,600.

Frequently Asked Questions
How is age calculated in months?
Months are counted as full calendar months between your birth date and today. If your birthday has passed this year, months start from your last birthday.
What is my zodiac sign?
Zodiac signs are based on birth month and day. The calculator determines your sun sign from the standard Western zodiac date ranges.
Does it handle leap year birthdays?
Yes. If born on February 29, the calculator uses March 1 for non-leap years to keep the count accurate.
