Mistake

 * The Gregorian calendar is approximately $1$ day ahead every $3333$ years.

Correction
This is at odds with Discrepancy between Gregorian Year and Tropical Year, which appears in section $365 \cdotp 2422$.

This demonstrates that after approximately $3318$ Gregorian years, the Gregorian calendar starts one day later relative to the tropical year.

This section has been dropped from of $1997$.
