Age Calculator: Determine Age from Birth Year
When someone is asked how old they are, most of us answer in terms of years – so how many years have passed since their birth. This is what people commonly refer to as their biological age, and it can be useful for determining things like legal drinking or voting ages. However, when we are talking about human life expectancy, we tend to use a slightly different definition of age, which is called chronological age.
Our age calculator is designed to help you determine your Tool to Calculate Age from Birth Year current age based on a date of your choice. You simply enter the data for your date of birth and another date in mm/dd/yyyy format, and we will calculate the number of years, months, and days you have been alive. The calculations are made to account for leap years, and the varying number of days in each month, so you can be sure that you will have an accurate result.
You can also use this calculator to find the age of something that was born on a certain date, such as a historical monument or a vintage/collectable item. This is especially useful when the full date of birth might be considered personally identifiable information, but you want to know how old a building or object was at a particular point in time. To do this, simply fill in the ‘Date of Birth’ field with the required date and leave the ‘Current Age or Age as of’ field blank.
If you need to find your age from a specific date, and the date of birth is not known, you can calculate your age in Excel using the DATEDIF function. To do this, select the cell you wish to insert your age formula in, and click the DATEDIF button in the Ablebits Tools tab. This will display a list of all possible DATEDIF formulas, including one that will find the age from the date of birth. To use this formula, select it and click OK. This will automatically insert the DATEDIF formula into the selected cell, and you can double-click the fill handle to copy it down the column.
Alternatively, you can make your own age calculator in Excel by using the AGE() function, which is available in all versions of Microsoft Excel. This is a little bit more complicated, because it requires that you know the day and year of a person’s birthday, which might be difficult to obtain for some people. The AGE() function will work for any date in the future or past, so you can use it to figure out how old you will be on any future date. This method is more accurate than the DATEDIF method, but it will require you to know the exact date of a person’s birth. It will also take longer to run, because it will need to perform a series of complex mathematical operations. This is why many people choose to use an online age calculator instead of a manual calculation.
