Today was not an ordinary day. Can you guess what happened today?
You mean post a chart with time of the event?If you post the chart as an event chart with the applicable time chart of the event, you could help the mundane astrologers practice their learning and interpretations?
Horary is to answer a pressing, heartfelt question about what did or may come to pass. Without there being any actors [that is, querent, quesited] and an event or story line, there is no way to delineate the chart.
You question is not in the domain of horary.
I will take a try at the event chart - the moment of the event chart.
I can't say that I can 'tell you what happened' but I might try to tell you what all the operators in the chart were doing at the time...?
