Events that occurred on 15 February.
 On Earth
- 1896 - Arthur Tolkien, J.R.R. Tolkien's father, dies.
- 1991 – The first "Colloquium on the Languages of Middle-earth" starts at the house of E.L.F. member Bill Welden. It lasts until the 18 February.
 In Arda
- T.A. 3019: (See note)
In editions prior to the 50th Anniversary Edition, the Tale of Years lists the two events of T.A. 3019 at 14 February. Since it is clear from the narrative that the latter event occurred one day before departure on 16 February, this causes a problem in the chronology. Hammond and Scull decided to fix the Tale of Years so that the Mirror of Galadriel-sequence happened on 15 February. The return to life of Gandalf was also moved to today, for reasons unclear.
