A care schedule proposal device comprising: a urination data storage unit that stores, together with urination time instant data, urination amount data of a wearer as acquired from a urine absorption amount of an absorbent article that absorbs urine; an absorbent article information storage unit that stores article information including a urine absorption capacity of the absorbent article; a changeable time storage unit that stores a changeable time instant or a changeable time period that can serve as a candidate for a changing time instant for changing the absorbent article; and a changing schedule proposal unit that proposes a changing schedule for changing the absorbent article, wherein: the changing schedule proposal unit includes a changing schedule computation unit and a changing schedule outputting unit; the changing schedule computation unit finds, on the basis of the urination amount data and the urination time instant data stored in the urination data storage unit, a total urination amount within a predetermined time period defined by a wearing-start candidate time instant and a wearing-end candidate time instant which are selected from the changeable time instant or the changeable time period stored in the changeable time storage unit; characterised in that the changing schedule computation unit performs, by comparing the total urination amount that has been found and the urine absorption capacity of the absorbent article stored in the absorbent article information storage unit, computation for finding at least either the absorbent article or the predetermined time period in a manner that the urine absorption capacity of the absorbent article does not fall below the total urination amount; and the changing schedule outputting unit presents schedule information including at least either the absorbent article or the predetermined time period found by the changing schedule computation unit. a urination data storage unit that stores, together with urination time instant data, urination amount data of a wearer as acquired from a urine absorption amount of an absorbent article that absorbs urine;
