Answer 1

The Reckoning of Time from the Two Trees Years 1-1100
The Count of Time begins on Aman. After an hour of waxing, Telperion shines at its full for six hours, then wanes for an hour into darkness. Laurelin, likewise, first has an hour of waxing while Telperion wanes, and then shines at its full for six hours until its hour of waning mingles with the hour of Telperion's rekindling. Taken together, the two six-hour periods of full shining are accounted a single day of twelve hours.Aulë makes the Seven Fathers of the Dwarves. For Yavanna's sake the Ents are born; for Manwë's, the Eagles.They first appeared after the awakening of the Elves, when spirits sent by Eru entered the World and inhabited certain of its living things (the Ents first appeared at about this time, for the same reason).
