date format

[Carlaf_93]

Good morning,

i'm writing a date like this:  01/01/2018 in a variable

i would like to calculate a year before from this in another variable.

It works if i define it like: variable2= $(variable1)-345 but i would like to set like year()-1

Any ideas?

Hi @Carlaf_93 , please try this :

variable2 = addmonths($(variable1), -12)
