What the numbers do and don't tell you
Which sign the Moon is in is astronomy. Astrology reads the Moon's sign as the day's emotional tone. That is an interpretation, and this calendar cannot prove or disprove it.
How we calculated: the Moon's apparent ecliptic longitude from the public-domain (Meeus) lunar formulas in our chart engine, searched every five minutes and refined to the minute at each 30-degree boundary. Treat each time as accurate to within a quarter of an hour.
