Younger Days

From Tolkien Gateway
"The Elder Days are gone. The Middle Days are passing. The Younger Days are beginning."
Saruman[1]

The Younger Days were those that succeeded the Middle Days in Middle-earth. This term was applied to the years of the Fourth Age (and beyond it) following after the Downfall of Barad-dûr. It was a time when the Dominion of Men at last came into its full extent.[2]
