Formula field for calculate age by using DOB

HI All,

 

How to create a fomula field for my age field ? It will be calculated by using the Date_of_Birth__c field. I have a fomula.

 

IF(MONTH(TODAY())>MONTH(DOB_API),YEAR(TODAY())-YEAR(DOB_API),IF(AND(MONTH(TODAY())=MONTH(DOB_API),DAY(TODAY())>=DAY(DOB_API)),YEAR(TODAY())-YEAR(DOB_API),(YEAR(TODAY())-YEAR(DOB_API))-1))  

 That's from Ankit's blog. But I don't know how to use it and where to use it.

 

Thanks in Advance

Yes thats a correct formula , you can use above

If you want to go for smaller formula

 

Use this one : From http://forceschool.blogspot.com/2011/06/age-calculation-formula.html

 

IF(ISNULL(DOB__c) , DOB__c , FLOOR((TODAY()-DOB__c +1)/365.2425))

 Now to your question how to use it.

 

1) Create a formula field return type Integer

2) Use any of the formula , replace your date field API Name with DOB__c

 

Then you will see this Calculated Age in your formula field.

@Chamil Good to know someone is reading my blog :)

 

@Shashikant Thanks for sharing this sort trick and it worked for me too, but there was a small change :

 

I have converted the return type from integer to text and formula to :

 

IF(ISNULL(SLAExpirationDate__c) , TEXT(SLAExpirationDate__c) , TEXT(FLOOR((TODAY()-SLAExpirationDate__c +1)/365.2425)))

 As I was unable to compile the formula provided.

 

Thanks

Problems:

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

code:

if(
MONTH(ramki__DOB__c) = 2 &&
DAY(ramki__DOB__c) = 29 ,
DATE(IF(Year(today())<=Year(ramki__DOB__c),
Year(ramki__DOB__c),
IF(
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))
),
MONTH(ramki__DOB__c),DAY(ramki__DOB__c)),
if(Year( today()) <= Year( ramki__DOB__c)  ,
DATE(Year(ramki__DOB__c),MONTH(ramki__DOB__c),DAY(ramki__DOB__c)) ,
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)

Use Simple Formula If You show only Age

1) Create a formula field return type "Number"
2) Use Formula i below mentioned  , replace your date field API Name with DOB__c

     
       ( TODAY() - DOB__c )/365
