Lunisolar faggotry.
Babylonians used intercallary days (monthless days) to make up for the discrepancy between lunar cycles and solar cycles.
Jews, and later the Romans, decided that was needlessly complicated and retarded so they shifted away from relying on moon phases for calendar days while keeping approximate month length.

easy, romans are superstitious and prideful, 2 days were subtracted from their unluck month and added to july (caesar the great-uncle) and august (octavian) by octavian himself
