An age calculator works out the precise difference between your date of birth and any chosen date. While a quick mental calculation can give years, the full breakdown into years, months and days requires careful date arithmetic that handles month lengths and leap years correctly. The InstantTool age calculator does this instantly and also shows your age in total months, weeks and days.
