'Festival' 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.

With joy they celebrated the festival of unleavened bread [for] seven days, because Yahweh had made them joyful and had turned the heart of the king of Assyria toward them in order to help them with the work of their hands on the house of the God of Israel.
