About the month
The month derives from the Moon's orbital period (about 29.53 days). Calendar months were standardized by Julius Caesar in 46 BCE and later refined by Pope Gregory XIII in 1582.
In everyday use the month appears in billing cycles, rent payments, subscription services, and seasonal planning. As a point of reference: human pregnancy lasts about 9 months (approximately 280 days).
