Jon D. Mikalson 
The Sacred and Civil Calendar of the Athenian Year [PDF ebook] 

From epigraphical, archaeological, and literary evidence Jon D. Mikalson has here assembled all relevant data concerning the dates of Athenian festivals, religious ceremonies, and legislative assemblies. This information has been used to revise and update our knowledge of the calendar as it reflects Athenian life.
The facts and conclusions that emerge from the author’s analysis correct some earlier assumptions. He brings to light new information concerning the meeting days of the Athenian Assembly and the Council, and establishes the days of the monthly festivals. Annual festivals are either dated exactly or fixed within closer time limits. The result of the author’s rigorous approach is a collection of reliable evidence as to what religious and secular activities occurred on specific days of the Athenian year.
