Hi all,
I am looking for some help with 2 formulas please, first I need to work out the difference in the XyXm format between the information in the column SA against AA. So for this versions 39y4m - 36y4m, but I need this in in formula to be able to copy it for all pupils. The AA is a formula I input based on the dated 20/08/2019 - 29/03/1983 and then SA is manual input based on a test from another system that I manual transfer across.
| Pupil | Date of Birth | August | 20/08/2019 | |
| dd/mm/yyyy | AA | SA | DIFF | |
| Simone Evans | 29/03/1983 | 36y4m | 39y4m | I need help here! |
This test will be conducted 4 times over the year, so my second formula I would like to add is the impact from the second time this test is conducted. I know there AA and SA would need to be calculated, but we would also need to take into account the difference from the August test.
| Pupil | Date of Birth | August | 20/08/2019 | Nov | 15/11/2019 | ||
| dd/mm/yyyy | AA | SA | DIFF | AA | SA | I | |
| Simone Evans | 29/03/1983 | 36y4m | 39y4m | formula 1 | 36y10m | 39y11m | ???? |
I hope this makes sense! Please ask any questions.
Thanks, Simone

Hi Simone,
It makes sense, but not too much I'm afraid, mixing text with calculations is usually a bad choice.
The difference can be calculated with a formula like this:
=LEFT(B1,FIND("y",B1)-1)+SUBSTITUTE(RIGHT(B1,LEN(B1)-FIND("y",B1)),"m","")/12-(LEFT(A1,FIND("y",A1)-1)+SUBSTITUTE(RIGHT(A1,LEN(A1)-FIND("y",A1)),"m","")/12)
As you can see, it's not easy to break the text to make calculations, you should use numbers and format them to display in other formats.
39.3333 is 39+4/12, can be displayed as 39 y 4/12 m with this custom format: ## "y" #/12 "m"
The cell holds a real numeric value that you can make calculations with, much easier in next calculations.
