Japan has their own way to call the month.
For an example, October is called ‘Kan-na-zuki’ or ‘Kami-nashi-zuki’ which stands for the Gods absent month.
Japanese Shito believers consider that there are millions of Gods in the world. In October, these Gods gather at Izumo Shrine in the state of Izumo, which is a part of Shimane prefecture today, to have an annual meeting.
By the way, citizens living in the Izumo area calls October ‘Kami-ari-zuki’ which stands for Gods existing month. Interesting, isn’t it?
