Greco-Roman Sacred Calendar
A source-visible 2026 historical reference calendar. Ancient dates remain primary; Greek Gregorian dates are clearly identified as modern Attic-calendar planning reconstructions.
Dating discipline: Roman fixed festivals map directly to their calendar month/day. Greek civic dates are lunisolar and move each year. This 2026 display is cross-checked to a published modern working reconstruction, while every card preserves the historical Attic date and dating confidence.
