'Year' in the Bible

It happened, at the return of the year, at the time when kings go out [to battle], that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David stayed at Jerusalem.

There was a famine in the days of David three years, year after year; and David sought the face of Yahweh. Yahweh said, "It is for Saul, and for his bloody house, because he put to death the Gibeonites."
