Months

The month is a unit of time derived from the Moon's orbital period (approximately 29.53 days per synodic cycle). The Gregorian calendar uses months of 28, 29, 30, or 31 days. In science, the average calendar month is often approximated as 30.44 days (365.25/12). Financial calculations, loan amortisation schedules, and rental agreements are almost universally structured around calendar months.

Days

The day is defined for civil timekeeping as exactly 86,400 seconds (24 hours). Two definitions coexist in astronomy: the solar day (averaging 86,400 seconds) and the sidereal day (approximately 86,164 seconds — 4 minutes shorter), as Earth must rotate slightly more than 360° to bring the Sun back to the same sky position due to its orbital motion. In medicine, the circadian rhythm operates on a near-24-hour cycle tightly coupled to the solar day.
