Appendix A contains genealogies of the royal house of Númenor. Appendix D gives details of the Númenórean calendar, including special intercalation in the years 1000, 2000 and 3000, and notes on how this system of intercalation was disrupted by the designation of S.A. 3442 the first year of the Third Age. In addition, several sections of Unfinished Tales deal extensively with Númenor and several of its kings. Also, at the end of The Silmarillion, Akallabêth recounts the fall of Númenor and its kings, and also the rise of Gondor and Arnor.
