'Appointed Time' in the Bible

And when the appointed time of every damsel came that she should come to the king Ahasuerus, after that she had been twelve months in the decking of the women - for their decking must have so much time, namely six months with Balm and Myrrh, and six months with good spices; so were the women beautified -

The Stork knoweth her appointed time; the Turtledove, the Swallow and the Crane consider the time of their travail: but my people will not know the time of the punishment of the LORD.
