The factors behind the scores
Mercury retrograde
Station to station — the traditional caution for messages, deals, and signatures.
Moon phase
Orrery’s rules favor a waxing Moon for launches and a waning Moon for commitments.
Your decision's factor
Activity-specific rankings use the Moon’s next exact aspect to a selected planet, such as Mercury for a pitch. Overall rankings do not use applying aspects.
The Moon's house
Activity-specific rankings include the Moon’s Whole Sign house when your location is known. Overall rankings do not use houses.
How the scores work.
Kairos, Orrery’s calculation engine, uses JPL ephemeris data for planetary positions. Orrery then applies its published astrological rules to rank the times.
The explanation uses statements written from the computed data. Scores reflect Orrery’s chosen rules; they do not measure the chance of a successful outcome. Your schedule and other people’s availability still come first.
