I am trying to create a formula that references a date of birth field (Date), and acts as a countdown until that date occurs again next. For instance, if someone has a Date of Birth of 06-09-1983, I want to know how many days until 06-09 occurs again.

Make a formula duration field and use the following:


var number Age=(Year(Today())-Year([DOB])-1)
+If(Month(Today())>Month([DOB]),1,0)
+If(Month(Today())=Month([DOB]) and Day(Today())>=Day([DOB]),1,0);

var date Birthday=AdjustYear([DOB], $Age+1);

$Birthday-Today()



You are basically finding the age, finding the next birthday, and then finding the difference (duration) between the birthday and today.
