Calculate your exact age in years, months & days
Our free online age calculator computes your exact age from your date of birth to any given date. Simply enter your birth date, and the tool instantly shows your age broken down into years, months, and days. It also displays your total time alive in months, weeks, days, and hours for a fun perspective on your life so far.
The calculator uses precise date arithmetic that correctly accounts for varying month lengths and leap years. Beyond basic age computation, it reveals your zodiac sign based on your birth date, tells you the day of the week you were born, and counts down the days until your next birthday. Whether you need your exact age for official documents, visa applications, or just curiosity, this tool delivers accurate results instantly with zero server processing -- everything runs right in your browser.
An age calculator returns your exact age from a date of birth — years, months and days — by counting calendar dates rather than dividing total days by 365.
SnoopTool's age calculator also shows your age in total months, weeks, days, hours and minutes, and tells you how many days remain until your next birthday. It handles leap years and month lengths correctly.
