Perhaps we’d have entirely solar-based calendars with four month-like divisions for the seasons, based on the angle of shadows cast by the Sun (I hear the Mayans had these huge dial things that just counted from 1 to 365) and leap days added onto one season every few years.
Physical seasons, and the modern western calendar, are both based on the sun. Having two moons wouldn’t make a difference there.
Two moons would make the ocean tides more complicated, though.

You could simply ignore one moon for you calendar. 😄
