I have a work sheet which provides the ID number of a person (the first 6 digits are the birth date of the person YYMMDD). Another column requests age. How can I create a formula that will automatically calculate the age of the person as at the current date?

You can use the a formula...If yy is less that current year century is considered as 20.If yy is greater than current year century is considered as 19.. With the ID in A1 try the below formula and feedback =DATEDIF(DATE(IF(LEFT(A1,2)>TEXT(TODAY(),"YY"),"19"&LEFT(A1,2),"20" & LEFT(A1,2)),MID(A1,3,2),MID(A1,5,2)),TODAY(),"y") If this post helps click Yes --------------- Jacob Skaria "Tracey" wrote: > I have a work sheet which provides the ID number of a person (the first 6 > digits are the birth date of the person YYMMDD).

Ah, your question brings to mind the Year 2000 problem, which was due in part to the custom of using only two digits to specify a year. If no one was born in this century, then: =DATEDIF(DATE(LEFT(A1,2),MID(A1,3,2),MID(A1,5,2)),TODAY(),"y") But that may only be true for an unknown number of years, so you are going to have to supply the possible age range for your persons in order to devise a formula that will continue to work for the foreseeable future, or change your ID's to use four digit years. --ron
