What does waning mean?
The fortnight from Full Moon back to New, when the lit part shrinks each night until the Moon disappears. It runs about fourteen days, through the last quarter at the halfway point. Read as the half for finishing, releasing, clearing out and resting, which is the same plain logic as the waxing half read backwards. The dark few days at the end are traditionally for doing nothing in particular.
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.
