IF(DAY(Birthdate) >=

global class memberBirthdayBatch implements Database.batchable<contact>

      We cannot create birthday reminder using workflow because of the workflow conditions we give  flow will fire only when the record is edited or inserted or when ever it is subsequently meeting the user cannot update the record everytime inorder to fire it.

     You can also try creating time based workflow still it wont work for leap years. But there is a solution for this unless your org is not professional edition. You can try creating a apex scheduler class and create  scheduled job. The class will execute whenever time criteria meets. To test it you can run the anonymous code in developer console and check. I'l  post the code it will help you if u r working in Apex environment. check this code if the contact birthday is met todays date mail will trigger.its tested and 100% working.-----------------------


global class MemberIterable implements Iterator<contact>

   public MemberIterable()

   global boolean hasNext()
       if(i >= memList.size())
           return false;
       } else {

   global contact next()
       if(i > memList.size())
           return null;
       return memList[i-1];

1)If DOB is Feb 29 Leap year.How to find next birthday for that particular date?

No Need Validation rule for this code.

End-of-century years 1700, 1800,1900,2100 these years are not leap year in these problems are resolved.........

To find the next Birthday formula

How to create......

step-1: create the custom field for Date of Birth----It's type-Date

step-2: create the formula field for Birthday ---It's type-Date


iIF ( MONTH (ramki__DOB__c)=2 && DAY (ramki__DOB__c)=29,
OR(MOD(Year(Today())+ 4-MOD(Year(Today()),4),400)=0,
AND(MOD(Year(Today())+ 4-MOD(Year(Today()),4),4)=0,
MOD(Year(Today())+ 4-MOD(Year(Today()),4),100)<>0)),
Year(Today())+ 4-MOD(Year(Today()),4),
Year(Today())+ 8-MOD(Year(Today()),4))
IF (DATE (YEAR(TODAY()),MONTH(ramki__DOB__c),DAY(ramki__DOB__c)) > TODAY(),
DATE (YEAR(TODAY()),MONTH(ramki__DOB__c),DAY(ramki__DOB__c)),
DATE (YEAR(TODAY())+1,MONTH(ramki__DOB__c),DAY(ramki__DOB__c))

it's correctly worked for leap year dates.......
this is code for find the next Birthday friends......

Easily Calculate Age:

create formula field -------(Number)

Age=YEAR( ramki__BirthDay__c) - YEAR(ramki__DOB__c)
