An honest compact calendar
Phase dates use a mean 29.530588853-day synodic cycle. Moon positions use a compact low-order geocentric longitude estimate sampled and refined in UTC. Dates and times are approximate; near a boundary, use a current high-precision ephemeris.
No planetary retrograde dates are shown because this dependency-free calendar does not have the high-precision planetary ephemeris required to publish them responsibly.
What the downloaded calendar contains
The .ics file contains only this month’s principal lunar phases and approximate Moon-sign changes. Each event repeats the approximation note. It contains no account, birth data, note, or tracking identifier.
