About the Birthday Calculator
The birthday calculator shows how many days are left until your next birthday and how old you will turn. It also reveals fun facts about your birth date: your western zodiac sign, your Chinese zodiac animal, your birthstone and the day of the week you were born.

Formula and How It Works
The next birthday is your birth day and month in the current year, or next year if it has already passed. The countdown is the number of days between today and that date. Zodiac signs follow the standard tropical dates and the Chinese zodiac follows the 12-year animal cycle.
