10th millennium

The tenth millennium is a period of time that will begin on January 1, 9001, and will end on December 31, 10000.

Astronomical events

All these dates are in a uniform time scale such as Terrestrial Time. When converted to our ordinary solar time or Universal Time, which is decidedly non-uniform, via ΔT, the dates would be a couple of days earlier. Furthermore, they are only astronomical dates, so they are given in the astronomical format of Year Month Day, which allows them to be ordered.
