7. 'Olekukahi (first 'Oleku, days 7-10 mark the transition from less than half-lit moon to the more than half-lit moon): "the farmer does not plant on this day" (Kepelino); "'Ole" means "nothing," so planting and fishing may be not productive in the three "'ole" days [7-9 on the lunar calendar] (Handy and Handy).
8. 'Olekulua (second 'Oleku; Olekulua is the first quarter moon; the names for days 7-10 match the names of days 21-24 of the last quarter moon.): "farmers generally dislike it for planting"; "a good night for torching fishing" (Kepelino).
9. 'Olekukolu (third 'Oleku): "the farmer thinks little of this day"; "a good night for torch-fishing" (Kepelino).
10. 'Olepau (last 'Oleku): "it is a productive day, say the cultivators" (Kepelino). "Pau" means "end" so non-productivity is at an end (Handy and Handy).
