编年史略（Tale of Years）is the second Appendix to The Lord of the Rings. It is entitled The Tale of Years (Chronology of the Westlands). It primarily contains timelines (lists of years) from the Second, Third, and Fourth Ages and the events of those years. There are also a few brief narrative sections, including a short discussion of the Wizards and how Gandalf received the Ring of Fire from Círdan.
The Tale of Years was said to have been put together at the Great Smials with the assistance of material collected by Meriadoc Brandybuck, who collected much information from Rivendell.
