All times Universal Time (UT), solved to the minute. Eclipse rows give the kind seen at the best-placed point on Earth and the instant of greatest eclipse; where you stand decides what you see, and a partial or penumbral eclipse is listed on the same terms as a total one. An ingress is the crossing itself; a station is the standstill, as on the retrograde calendar; the equinoxes and solstices are the Sun's cardinal ingresses; meteor peaks are dates from the shower catalogue, not instants; an outer-planet aspect is listed at each exact pass, so a retrograde series is several rows. The Moon's signs and void-of-course windows are on the moon calendar, and every planet's daily position on the ephemeris table. Nothing here is read against a chart: for your own dates see the timeline.
