Calculate your exact age, compare birthdays, and discover your zodiac sign — all for free.
Enter your birth year to find your Chinese zodiac animal. Note: the Chinese zodiac year starts on Chinese New Year (late Jan – late Feb). If you were born in January or early February, you may belong to the previous year's animal.
Enter your date of birth in the Age Calculator above and select the reference date (it defaults to today). The calculator returns your age in years, months, days, hours, and total days lived — all calculated in your browser with no data sent to any server.
Use the Age Comparison tab. Enter two birthdays and the calculator finds who is older and by exactly how many years, months, and days. This is great for comparing the age gap between partners, siblings, or friends.
The Chinese Zodiac is a 12-year cycle where each year is associated with one of twelve animals: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. Your birth year determines your zodiac animal, which is said to influence your personality and destiny.
Western astrology divides the year into 12 signs based on your birthday: 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), and Pisces (Feb 19–Mar 20).
If you were born in 1990, you are either 35 or 36 years old in 2026, depending on whether your birthday has passed. Use the calculator above for the exact result including months and days.
The Age Calculator shows your total days lived. For example, a person who is 30 years old has lived approximately 10,950 days. Enter your birthday above to get your exact number of days.
