Frequently Asked Questions

How do I calculate my exact age in years, months, and days?
To calculate your exact age, subtract your birth date from today's date. First, count the full years from your last birthday. Then count complete months since that birthday. Finally, count remaining days. For example, if born March 15, 1990, and today is January 10, 2025: you're 34 full years old (since March 15, 2024), plus 9 months (March to December), plus 26 days (December 15 to January 10). Total: 34 years, 9 months, 26 days.
How many days have I been alive?
To find total days lived, multiply your age in years by 365.25 (accounting for leap years), then add days for remaining months and days. A simpler method: count days between your birth date and today. For someone born January 1, 2000, as of January 1, 2025: that's exactly 25 years = 9,131 days (including 6 leap years). Our calculator does this instantly and includes hours and minutes too.
What is my zodiac sign based on my birth date?
Western zodiac signs are determined by your birth date: Aries (Mar 21-Apr 19), Taurus (Apr 20-May 20), Gemini (May 21-Jun 20), Cancer (Jun 21-Jul 22), Leo (Jul 23-Aug 22), Virgo (Aug 23-Sep 22), Libra (Sep 23-Oct 22), Scorpio (Oct 23-Nov 21), Sagittarius (Nov 22-Dec 21), Capricorn (Dec 22-Jan 19), Aquarius (Jan 20-Feb 18), Pisces (Feb 19-Mar 20). Enter your birth date to see yours.
How do I find my Chinese zodiac animal?
The Chinese zodiac follows a 12-year cycle, with each year represented by an animal: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. The cycle repeats, so if you know one year's animal, you can count forward or backward. 2024 is Dragon, 2023 was Rabbit, 2025 will be Snake. Note: The Chinese New Year falls between January 21 and February 20, so early-year birthdays should check the exact date.
How many days until my next birthday?
To calculate days until your birthday: if your birthday hasn't occurred this year, subtract today's date from your birthday date. If it already passed, add your birthday to next year and subtract today's date. For example, if your birthday is July 15 and today is January 10: July 15, 2025 minus January 10, 2025 = 186 days. Our calculator updates this daily and shows the exact countdown.
