How Your Age Is Calculated

Your age is calculated by comparing your date of birth to the current date (or a specific date you choose). The calculator accounts for leap years, different month lengths, and even the time of day if provided.

Precision Age

We calculate down to the second if you provide your birth time. Results update instantly in "Age Now" mode for the most accurate reading.

Zodiac & Generations

Your Western zodiac is based on month and day of birth. Chinese zodiac follows a 12-year cycle of animals. Generations span 15-20 year cohorts with shared cultural experiences.

Planetary Age

Each planet orbits the sun at a different speed. A year on Mercury is 88 Earth days. On Jupiter it is 4,333 days. Your age in "planet years" is your Earth age divided by that planet's orbital period.

Frequently Asked Questions

How do I calculate my exact age?

Enter your date of birth and optionally your time of birth. The calculator will show your exact age in years, months, days, hours, minutes, and seconds. You can also choose to calculate your age as of a specific date rather than just "now".

What is my zodiac sign?

Your zodiac sign is determined by your birth date. The calculator automatically determines your Western zodiac sign based on your date of birth, along with your Chinese zodiac animal year.

What generation am I?

Your generation is determined by your birth year. The calculator classifies you into Gen Alpha (2013+), Gen Z (1997-2012), Millennial (1981-1996), Gen X (1965-1980), Boomer (1946-1964), or Silent Generation (1928-1945).

How old would I be on other planets?

Each planet has a different orbital period around the sun. Your age on Mercury would be much higher because its year is only 88 Earth days. On Jupiter, with a 4333-day year, you would appear much younger.

What is my birthstone?

Birthstones are gemstones associated with each month of the year. January is Garnet, February is Amethyst, March is Aquamarine, April is Diamond, May is Emerald, June is Pearl, July is Ruby, August is Peridot, September is Sapphire, October is Opal, November is Topaz, and December is Turquoise.
