Age calculation

Yes, it's possible to auto-calculate the mother's age on the baby's birth date using a script or formula in the read-only text box. Consider using an Age calculator because this feature saves time, ensures accuracy, and simplifies record-keeping.

Try this as custom calculation script of 'age' field:

var date1 = this.getField("BM DOB").valueAsString;
var date2 = this.getField("Acq Date").valueAsString;

if (date1 === "" || date2 === "")
 event.value = "";
else {
 var mdob = new Date(date1);
 var bdob = new Date(date2);
 var age = bdob.getFullYear() - mdob.getFullYear();

 if (bdob.getMonth() < mdob.getMonth() ||
   (bdob.getMonth() === mdob.getMonth() && bdob.getDate() < mdob.getDate()))
    age--;
 event.value = age;}
