  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Let ( [ d1Float = Year ( date1 ) + Month ( date1 ) / 100 + Day ( date1 ) / 10000; d2Float = Year ( date2 ) + Month ( date2 ) / 100 + Day ( date2 ) / 10000 ]; Int ( d2Float - d1Float ) ) Click to copy

This calculation returns an integer year count between the two supplied dates -- perfect for calculating someone's age. It correctly handles all cases and is unaffected by (and unconcerned with!) leap year and other calendar variations/anomolies. This is accomplished by converting each date to a "floating point number" and then simply taking the integer portion of the difference.
