365.2425

THESIS Main (won): the Gregorian calendar (1582), with a mean year of 365.2425 days. Ghost (lost, slowly): the Julian (365.25), kept by Britain until 1752, hence Salem's 10-day gap. COMPUTEDAgainst the tropical year (≈ 365.24219 d), the Julian calendar drifts about 1 day per 128 years; the Gregorian about 1 day per 3,200 years. The equinox date drifts live as centuries pass.

MNEMONIC "Skip three leap days in four hundred years."
