Please let me know the format of the of the date of birth field so that we can trace out the day,month and year separeately then after the logic is so simple.

dd/mm/yyyy is the format

Create a new Date object for today's date, get the input and split to get the day/month/year values and then compare. I'm sure you know how to work out someone's age from two dates.

var date_of_birth=$('Id of the field where you have entered the DOB');
var currentDate=new Date();
var day = currentDate.getDate();
  var month = currentDate.getMonth();
  var year = currentDate.getFullYear();
  month+=1;//As month returned starts from 0 like 0 for January
 
var Dob=date_of_birth.split('/');
var Dob_day=Dob[0];
var Dob_month=Dob[1];
var Dob_year =Dob[2];

Now you can calculate using different function I know this will be a tricky but I hope you can do because this is one of the basic programming
