I've seen different guides and even the official prima guide is unclear. I understand it is the last friday of april. Some guides say to let weeds pile up so you can get more items but others make it seems that weeds just appear on weeding day to pick. I know you have to go other players towns for items too, but i'm not sure on how that works either. MOSTLY I need to know if I need to turn off beautiful town ordinance a month early in order to get enough weeds or not to worry.
