Differences between 2 values

[HishamAT]

Hi

I have a field called NHC that has a numerical value and I need to calculate the difference between NHC for the current month and NHC for the same month in the year 2019 or any year before.

Can anyone please guide me on how to create it? 

Thanks

• Let's say that I have a field called NHC = 7.6 at year 2022 on the month of December 
• Same field at year 2019 was 10.4 at the month of December 
• I need to calculate the difference between the same fields for the same month between the years 2022 and 2019
