Hi Djibril,

You can actually use the d2 adddays function to substract days.
Just use a negative number.
For example d2:addDays(V{current_date}, -3) will return the date three days ago.

Best,

Edouard

Djibril,

What if you use a negative value in d2:addDays()? Something liked d2:addDays(your_date, -10).

I haven’t used that specific function, but I imagine it will accomplish what you’re looking for with a date returned.
