Duration calculation based on lables on Status column

Hi,
I have a column named Stages that shows each stages of the entire deals.
And I set the automation on each date column to set it today when column changes to every each column.

I’d like to calculate the duration of each stages between newly changed stage and item creation date.

How should I set the function for it?

Thank you

Hi @davelight,

Use the Days function.

DAYS({Date1} , {Date2})
