Etymologically, the entry records: From military time, in which hours before 10:00 am are prefixed with a zero, read as "oh", and 00 minutes is read as "hundred", as in oh five-hundred for 5:00 am. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is oh dark hundred, spelled O-H- -D-A-R-K- -H-U-N-D-R-E-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
