When an Otoshiyori served for a month in the monthly rotation, she entered 'Chidorino-ma' (literally, plover room) in the Gotenmuki area around 10 AM, and summoned female servants, directing everything there without going out of the room.
月番は毎朝四ツ時（10時ごろ）に御殿向の「千鳥之間」に詰めて自身はそこを出ることなく、女中たちを呼びつけて一切を指図したという。
