Use this free age calculator to calculate your age online — get your exact age in years, months, days, hours, and minutes, plus your next birthday countdown and zodiac sign.
Enter your date of birth in the first field, then confirm the date you want to calculate your age as of in the second field — it defaults to today so you can see your current age right away. Click Calculate Age and your results appear instantly below.
Your age is broken down six ways: exact years, total months elapsed, total weeks, total days, total hours, and total minutes. The teal panel below the stats shows your next birthday countdown, the day of the week you were born, your Western zodiac sign, and your Chinese zodiac animal year.
Everything runs entirely inside your browser — no data is sent to any server and nothing is stored or tracked. You can also calculate the time between any two dates by adjusting the "Calculate Age As Of" field to any date, past or future.
Enter your date of birth above and click Calculate Age. The tool computes your precise age in years, months, and days — not a rough estimate. It accounts for leap years and the varying number of days in each month so the result is always accurate to the day.
After calculating, the "Total Days" card shows exactly how many days you have been alive. For someone who just turned 30, this is typically around 10,957 days, though the exact number depends on how many leap years fall within their lifetime.
Enter your date of birth and click Calculate. The "Day of Birth" field in the teal panel will tell you the exact day of the week — for example, "You were born on a Wednesday." This works for any date going back centuries.
Enter the earlier date in the "Date of Birth" field and the later date in the "Calculate Age As Of" field, then click Calculate. This works for any two dates — not just birth dates — making it useful for calculating how long ago any event occurred.
Your Western zodiac sign is determined by your birth month and day. The twelve signs are: 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).
