Get a notification when the date is hit

[DAIRYMAN]

hi newbie here,

Is there a way to set up a bot that sends a notification after 3 months of the entered date. For example, in this app, I want to get a notification that alerts me to get a pregnancy diagnosis done of a cow after 3 months of artificial insemination here the cow number is 1 and its A.I. was done on 6th December and I would get a notification on 6th march telling me to get its P.D. done (I used maxrow slice which grabs the last date of A.I. Done and displays it here since A.I. fails sometimes and we have to do it again and change the date)
