Later incarnations boiled down to "Anything that can go wrong will go wrong."

The law has numerous corollaries involving the exacerbation of the potential for and/or likelyhood of disaster.

35 years later, in 700 BC, two more months were added, bringing the "year" to 355 days. The new months were: Januarius (after Janus, the two-faced god); and Februarius (from Februa, a Roman Festival).

By 46 BC the calendar had slipped badly in synchronization from the seasons so Julius Caesar reformed it again, bringing the day total to 365 per year. The Roman Senate renamed the month Quintilis after Caesar, calling it Julius (July), and giving it 31 days.

Later, Augustus had the number of days of each month standardized to their current count and the month Sextilis renamed Augustus and also given 31 days ... he swiped one day from Februarius making it 28 days long. Lastly, he changed the beginning of the year from March to January 1st.

After almost 1600 years the vernal equinox had again drifted from the expected March 21 date causing Easter to become later and later in the church calendar. Pope Gregory XIII reformed the calendar to make centennial years NOT be leap years except for centennial years divisible by 400. His 1578 edict went into effect in October, 1582, dropping ten days by having Thursday the 4th be followed by Friday the 15th. Non-Catholic countries took a while to adopt the Gregorian calendar: Britain adopted it in 1752, while Russia waited another 160 years to change (they adopted the leap year rules but didn't do a date shift as other countries had).

The calendar still has a +1 day error for every 3233 years, so a "centennial years divisible by 4,000 are not leap years" rule has be proposed but not adopted.
