Hi! How are you?
User 03/06/2018 - 05:21
Good thank you. How are you?
Excelchat Expert 03/06/2018 - 05:21
I'm good, thanks for asking. :)
Excelchat Expert 03/06/2018 - 05:22
To confirm my understanding - you need to calculate for difference of an identified date to today's date expressed in "days". Is this correct?
User 03/06/2018 - 05:22
correct
User 03/06/2018 - 05:23
but i would also like to know how long the match length is in years
Excelchat Expert 03/06/2018 - 05:24
Sure. Could you see the updated columns (C and D) on the document preview?
User 03/06/2018 - 05:25
yes this is how I would like it to look. Could you please give me a step by step guide on how to do this?
Excelchat Expert 03/06/2018 - 05:25

So in cell C2, which is the adjacent cell to the first date in column B (10/22/14) - you enter the formula =DATEDIF(B2,TODAY(),"Y")
Excelchat Expert 03/06/2018 - 05:27
The DATEDIF function is composed of three parts - 1) Start Date = B2, 2) End Date = TODAY(), 3) units = "Y" or in years

yes

if I remove the "Y" does it show it in days?
Excelchat Expert 03/06/2018 - 05:30
Cool. So the same formula is applied in cell D2
Excelchat Expert 03/06/2018 - 05:30
if you change "Y" to "d" then you get answer in days

User 03/06/2018 - 05:34
I had problems trying it in my own table
Excelchat Expert 03/06/2018 - 05:34
Cool
Excelchat Expert 03/06/2018 - 05:35
I believe you could do it :)
