I'd like to substract 1 from the date.

 

Thank you

Hi @FranckGbadamass ,

 

You might wanna consider this M Power Query:

 

Date.AddDays ( [Merged.1], -1 )

 

Does this help?

Hi @FranckGbadamass ,

 

I may have reproduced your wrong scenario.

You should use Date.ToText() and Number.ToText().
