# How Many Days in an Egyptian Year? Evidence from the Antikythera Mechanism

R. J. Dickens, Stuart Malin, 2024. _Horological Journal, April 2024, 140–145_.

Least-squares re-analysis of the same hole data by two retired Royal Greenwich Observatory astronomers; criticises the 2020 statistics (triplet overcounting), finds N = 352.3 plus or minus 1.5, puts 365 below one chance in ten thousand and supports a count near 354.
