'Appointed Time' in the Bible

After [this, they presented] the daily sacrifice of burnt offerings, [the offerings] for the New Moon Festival, and for all of the appointed times consecrated for Yahweh and for all who gave a freewill offering to Yahweh.

Let now our rulers of all the congregation stand, and let all them which have taken strange wives in our cities come at appointed times, and with them the elders of every city, and the judges thereof, until the fierce wrath of our God for this matter be turned from us.
