Shubunno hi (Autumnal Equinox Day)
This holiday falls on or around September 22. This day is the counterpart of Vernal Equinox Day, and on this day the sun crosses the equator again, making night and day of equal length.
Just as in spring, in Buddhist temples, special services for ancestors are performed, and people clean the tombs of their ancestors and pay homage to their spirits, offering flowers and incense.
There is a popular saying in Japan, "No heat or cold lasts beyond the Equinox Day." (Atsusa samusa mo higanmade)
