Setsubun, while tied to the lunar calendar, usually falls on the 3rd of February. This year's shift to the 2nd of February is rare and happened in 2021 for the first in over a century. While Setsubun has occasionally been on the 4th of February, it will return to the 3rd in 2022, then shift to the 2nd every four years starting in 2025. A double 2nd of February Setsubun will happen in 2057 and 2058, and a 4th of February Setsubun won't occur again until the 22nd century. This shifting has caused confusion, with some 2021 calendars incorrectly marking the date. Therefore, the National Astronomical Observatory of Japan has issued a reminder of the correct date.
