Omigoromo called 'suinou no omi' appears in documentary records, such as "Daihajime-washo" (written by Kanera ICHIJO), but the actual state has remained unclear; in recent times, it has been said to be another name for Becchoku no omi (or Nyogyo no omi (如形小忌), according to another account).
※なお『代始和抄』(一条兼良)などに「出納小忌」の名称があるが、実態は不明で、近世では別勅小忌の(一説では如形小忌の)別名とされていた。
