There are two ways to calculate age in Microsoft Access:

1. Using the DateDiff function

2. Using the Expression Builder

Using the DateDiff Function

The DateDiff function can be used to calculate the number of days, months, or years between two dates. To calculate age in years, simply specify “yyyy” as the interval. For example, the following formula will calculate the age of a person born on January 1, 1960:

DateDiff(“yyyy”,#1/1/1960#,Date())

This formula will return the number of years between the specified date and the current date.

Using the Expression Builder

The Expression Builder can be used to create more complex expressions, such as those that calculate age in years, months, and days. To access the Expression Builder, open the query in design view and click on the field that you want to calculate age in. Then, click on the Build button in the toolbar.

In the Expression Builder, type the following expression:

DateDiff(“yyyy”,[BirthDate],Date()) & ” years, ” & DateDiff(“m”,[BirthDate],Date()) & ” months, and ” & DateDiff(“d”,[BirthDate],Date()) & ” days”

This expression will calculate the number of years, months, and days between the BirthDate field and the current date.
