What is an ingress?
A planet crossing from one sign into the next. For the Moon this happens every two and a half days; for Saturn every two and a half years; for Pluto once or twice in a lifetime. The slow ones mark changes of era.
Where you see this in OrbHeaven
Your own chart is calculated from your birth details, and this definition is written out again there with your numbers in it rather than in the abstract. The chart, the glossary and thirty days of dated timeline are free, and nothing here is charged per question.
About a minute. Birth time optional, and no account until after you have seen it.

Everything that happens after you are born, which is where dates come from.
