- Dear John, et al,
-
- Can we cease this pointless discussion of decades and calendars? Surely it
- has little to do with MacApp.
-
- Hoping to give no offense, I remain
-
- Yours,

-
- P.S.: Although it is true that the Gregorian calendar system was derived from
- the pre-existing Julian system in 1582, the era, or year number, had been
- based on the birth of Christ since the Venerable Bede began the practice in
- 8th century.
-
- Further,the Gregorian calendar did not introduce leap years; every fourth
- year was a leap year in the Julian calendar. The Gregorian system added the
- rule than century years (those evenly divisible by 100) would only be leap
- years if they were also evenly divisible by 400, and supressed the 10 days
- that had accumulated in the Julian calendar by 1582 due to its lack of this
- rule.
-
- The Gregorian Calendar is still imperfect. It needs two additional rules to
- bring it into harmony with the solar year (365.2422 days): it should drop 1
- leap day every 4,000 years, and another every 20,000 years.
-
- It major deficiency, however, is the irregular lengths of the months, and the
- mismatch between the cycle of years/months and that of weeks. Both problems
- can be resolved by adopting a calendar of 13 months of 28 days each, with the
- year ending on an intercalated day belonging to no month or week. In this
- system (the Universal Fixed Calendar), every month would end on a Saturday,
- including the last month of the year, which would then be followed by the
- intercalated day, which would in turn be followed by the 1st of January, which
- would fall on a Sunday, as would the 1st days of all other months. Leap days
- would be intercalated at the end of the year, using the rules described above.
-
- The Universal Fixed Calendar ensures that all months are the same length and
- that any given day in the year falls on the same day of the week, in all
- years. One printed calendar would be good for all years; in the Gregorian
- system, there are 14 possible calendars.
