Elijah will resolve all disputes in the end of days, including those about the calendar and the times appointed for redemption.
The world will last for 6,000 years: 2,000 years of desolation, 2,000 years of Torah, and 2,000 years of the days of the Messiah. In the seventh millennium, the world will be rebuilt in glory.
The Holy One, Blessed be He, has set a time for redemption, but if Israel merits, the Messiah will come earlier.
The seventh millennium will be a time of peace and renewal, as it is written: ‘And on the seventh day, God rested and was refreshed’ (Exodus 31:17). So, too, the world will rest in the seventh millennium.
