'Appointed Time' in the Bible

the Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them, so that it should not fail, that they would keep these two days according to the writing thereof, and according to the appointed time thereof, every year;

to confirm these days of Purim in their appointed times, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had ordained for themselves and for their seed, in the matter of the fastings and their cry.
