Is there a way to calculate age in years, months & days?

Oops, one more change...


I had to modify one of the formulas, it was giving negative numbers.  Here is my revised formula



3)  [Age - Months] - Formula Numeric field - with formula: 


var Date OneMonthOldBirthday = AdjustMonth( [Date of Birth], 1);

var Number TodayMonth = Month( Today() );

var Number TodayDay = Day( Today() );

var Number BirthdayMonth = Month( [Date of Birth] );

var Number BirthdayDay = Day( [Date of Birth] );



If ( 

Today() < $OneMonthOldBirthday, 0,

$TodayMonth = $BirthdayMonth  and  $TodayDay >= $BirthdayDay, 0,

$TodayMonth = $BirthdayMonth  and  $TodayDay < $BirthdayDay, 11,



$TodayDay = $BirthdayDay and $TodayMonth > $BirthdayMonth, $TodayMonth - $BirthdayMonth,

$TodayDay = $BirthdayDay and $TodayMonth < $BirthdayMonth, $TodayMonth + 12 - $BirthdayMonth,



$TodayMonth > $BirthdayMonth  and  $TodayDay > $BirthdayDay, $TodayMonth - $BirthdayMonth,

$TodayMonth > $BirthdayMonth  and  $TodayDay < $BirthdayDay, $TodayMonth - $BirthdayMonth -1,



$TodayMonth < $BirthdayMonth  and  $TodayDay > $BirthdayDay, $TodayMonth + 12 - $BirthdayMonth,

$TodayMonth < $BirthdayMonth  and  $TodayDay < $BirthdayDay, $TodayMonth + 11 - $BirthdayMonth
