Transit
Your natal chart is fixed; the planets keep moving. A transit is a current planetary position forming an aspect to something in your birth chart — the standard tool astrologers use for timing.
Combined with astrocartography, transits add when to the map's where: a slow outer planet crossing one of your lines marks a season when that line's places are unusually activated. Transit-to-natal mapping is a deeper technique the interactive map is built to grow into.
