How the dates are computed
These calendars compare apparent ecliptic longitude at noon UTC on successive days and report the day-level boundary where motion changes direction. Each annual table includes the transition into retrograde and the return to direct motion; it does not claim an exact station time. Read the full calendar method and precision limits.
