Free age calculator — find your exact age and days until your next birthday
Our free age calculator tells you your exact age in years, months, days, hours, and seconds — plus a live countdown to your next birthday. Use it as a birthday calculator to see how many days until your birthday, find out which day of the week you were born, your star sign, and your Chinese zodiac year. The most complete free age calculator online — just enter your date of birth.
Enter your date of birth and click Calculate. The tool shows your age broken down into years, months, days, hours, minutes, and seconds, updating live every second.
The countdown shows the exact number of days, hours, minutes, and seconds remaining until your next birthday at midnight in your local time zone.
The calculator automatically works out the day of the week for any date of birth, so you can find out if you were born on a Monday, Friday, or any other day.
Enter your date of birth as normal — the results show your age as of today. For a future date, you can use the Days Counter tool to add the difference onto your current age.
The calculator automatically determines your Western astrological star sign (e.g. Aries, Taurus, Gemini) based on your day and month of birth and displays it alongside your age.
