/sipasu/ → /ɕifasu/ → /ɕihasu/

Од Old Japanese of unknown derivation. First appears in the Nihon Shoki of 720 CE.^[3].

Possible etymologies

From 師(し) (shi, “Buddhist monk”) + 馳(は)す (hasu, “to hurry, to make run”, modern 馳せる), as there were traditionally many services for monks to attend during this month. However Old Japanese verbs usually do not form nouns with their terminal form.^{[note 1]}^[4]^[5] If this is a folk etymology, the kanji would be ateji, as it is generally regarded.
はす (hasu) may be derived from 果(は)つ (patu, “to come to an end”, modern 果てる), or a perhaps related root *pas- meaning "edge; division between two things", referring to the end of a year. Compare 橋(はし) (hashi), 端(はし) (hashi), 挟(はさ)む (hasamu).^[4]^[5] However all these sound changes remain unexplained.
