About Converting Centuries to Months
Centuries and Months are both everyday units of duration, and converting between them is one of the most routine calculations there is — scheduling, project planning, and billing all depend on it. Specifically: A century is 100 average Gregorian years, and a month uses the average Gregorian month.
Formula
months = centuries × 1200
This factor comes from each unit's defined relationship to the category's base unit: 1 centuries equals 3155695200 base units, and 1 months equals 2629746 base units, so dividing one by the other gives the direct centuries-to-months factor of 1200.
Simple example
1 century × 1200 = 1,200 mo
1 centuries = 1,200 months.
Real-world example
24 century × 1200 = 28,800 mo
24 centuries = 28,800 months.

History of the Months
The month originated from the Moon's roughly 29.5-day orbital cycle (a 'lunation'), used by many ancient calendars. The Gregorian calendar (1582), used internationally today, decoupled month lengths from the actual lunar cycle to fit 12 months evenly into the solar year, producing the familiar unequal 28-31 day months.
Historical origin. Months was not the invention of a single named person; it developed through the process described above.
