The term "Handy Tables" has been used repeatedly throughout this website. This is also a historical allusion to Ptolemy's Algamest, a famous book written around 100 C.E. that crystalized then current knowledge about sundials and planetary motion. After completing The Algamest, Ptolemy issued a supplement, called the Handy Tables consisting of useful data lookup tables for solving solar and planetary motion questions. By writing convention, most books about sundials include an appendix of handy tables.
