Incidentally, the reform of the calendar for the first time in 800 years gained topicality at that time; thus, Saikaku IHARA wrote "Koyomi (Ukiyozoshi), Calendar (Literally, Books of Floating World)," and Monzaemon CHIKAMATSU wrote "Kenjo no tenarai narabini shingoyomi (Wise Woman's Penmanship and the New Calendar)."
なお、800年ぶりの改暦は当時話題となり、井原西鶴は『暦(浮世草子)』、近松門左衛門は『賢女手習並新暦』を執筆している。
