- There was never a month lost!!!
- Because the year is defined by the cyclic extermal position of the sun
- (southmost, winter, for Romans; equal day, spring, for semetic and Persian).
- If the year the year was defined by when it crossed a certain point in its
- yearly run through the zodiac, then there would be a month lost, but no
- current culture defines the year as such. (The Egyptians defined the year
- by the rising of the star Sirius. Precession would cause the "star year"
- to be off from the "sun year" by 20 minutes each year or a month every
- 2000 years.)
