If you know the exact time, check the angles and Moon and Vertex in close (1°) conjunction , opposition, square to the planets. Additionally look which midpoints are being activated by the said objects that way.
All those should be very descriptive of the event in question.
And then check the overlays to YOUR natal and progressed chart (very close orbs, too, especially with the progressed chart).
If the angles or luminaries of that day (yes check Tr Sun, too) are not activating your natal chart in a very evident way, you have the wrong date.
