As for when the Hon-keizu was drawn up, it is speculated that from the words 'Jushiinoge Kono-myojin' (Kono-jinja Shrine, Junior Forth Rank, Lower Grade) of the central phrase, it was drawn up between July 3, 871 and January 24, 878, when Kono-jinja Shrine was ranked as Junior Forth Rank, Lower Grade (Reference: "Nihon Sandai Jitsuroku" (sixth of the six classical Japanese history texts)), supported by a footnote in the 'Kanchu-keizu' (see below) that says it was drawn up during the Jogan era (859 to 877).
また成立年代については、標記中に「従四位下籠名神」とあることから、籠神社が「従四位下」であった期間、すなわち貞観(日本)13年（871年）6月8日(旧暦)を上限とし、元慶元年（877年）12月14日(旧暦)を下限とするが（『日本三代実録』）、下述「勘注系図」の注記にも貞観年中（859～77年）の成立とある。
