Bible prophecy contains several periods of time. God uses catchphrases to help us identify these periods of time. In this case, He uses these "signs" in the heavens repeatedly to identify at period of time which takes place after the Tribulation period......
Matthew 24: 29Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
......but before the "day of the Lord.
Joel 2: 30And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke. 31The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of the LORD come.
