Field notes
The interface pairs front and back mechanism views with controls to advance a turn, month, year, or the next eclipse. Its guide explains the 235-month Metonic spiral and 223-month Saros cycle, and notes that the Egyptian calendar ring needed manual adjustment because its year is a quarter-day short. Date presets include the eclipse of Thales and a 2027 total solar eclipse.
