Hatsu-uma is the first Horse day of February, counted on the sexagenary cycle — the sixty-day sequence of stems and branches that Japan still uses alongside the Gregorian calendar for ritual purposes. On it, Inari shrines across the country, from Fushimi Inari in Kyoto to the smallest fox shrine behind a shop, are hung with red banners, and inarizushi is eaten.
No attendance figure applies.
The anchoring rule is the finding here. This is not a weekday rule, a fixed date or a lunar date: it is the first occurrence of a named day in a sixty-day cycle, which lands on a different Gregorian date each year and cannot be derived from any of our six timing classes without a lookup table.
We record it as anchored and flag the inadequacy rather than inventing a seventh class for one entry.
PlanningAnchored to a day of the sexagenary cycle rather than a weekday — a rule no Gregorian calendar carries.

Computed from the recurrence rule we record for this entry, not copied from a listing. A date marked ~ comes from a calendar conversion and the observance may fall a day or two either side.
