Difference in date

[vmjan02]

I have this records below

If the “PROJECT_NUMBER” is repeated AND “INCIDENT_CREATION_DATE” between the two incidents is less than 31 days then mark it as a "repeat"

I am confused as how shall I do it, as did countif as well to find the duplicate and then the diff in date but the records can be in any row.
