Hi, One easy way can be to add a helper column and use =MONTH ( B7) to find the Month number for the date of birth in column B and then in the lower part of column B we can use =COUNUTIF($B$7:$B$81, B84) to see how many people were born in the first month which gives the result as 4 in this case. Same can be achieved through a pivot table also.
Alternatively SUMPRODUCT function can be used to give a similar result. Would like to see what other methods can be used to solve this test. Hope that helps, Warm regards, Anand Kumar -- ---------------------------------------------------------------------------------- Some important links for excel users: 1.
