What is an ingress?
An ingress is the moment a body crosses from one zodiac sign into the next, and it is the cleanest kind of change a daily sky can report.
Signs are thirty degree segments of the ecliptic, so an ingress happens whenever a body passes a thirty degree boundary. The Moon does this every two and a half days, the Sun once a month, and Saturn roughly once every two and a half years.
In the tropical zodiac those boundaries are fixed to the seasons: the Sun's ingress into Aries is the March equinox, into Cancer the June solstice, into Libra the September equinox, into Capricorn the December solstice.
Undersky compares the sign a body occupies at the start and end of each day in universal time, so an ingress on a page means the crossing fell inside that window. It is a change of background, not an event happening to you.
