To put second in perspective: a heartbeat (about 1 s). In month, common references include a human pregnancy (about 9 mo).
The second was redefined in 1967 based on the vibration frequency of a cesium-133 atom (9,192,631,770 cycles), replacing earlier definitions tied to Earth's slightly irregular rotation.
Calendar months don't align neatly with the Moon's actual orbital period (about 29.5 days) — they were adjusted historically, notably by the Romans, to fit a 365-day solar year evenly.
