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.

  • 9106 November 5: Venus occults Regulus.
  • 9168 November 21: Mean solar time and atomic time will be two days apart.
  • 9361 August 4: Simultaneous annular solar eclipse and transit of Mercury.
  • 9622 February 4: Simultaneous annular solar eclipse and transit of Mercury.
  • 9682 November 16: Mercury occults Regulus.
  • 9847 November 21: Mars occults Regulus.
  • c. 9800: Earth's axial precession makes Deneb the North star.
  • 9966 August 11: Simultaneous total solar eclipse and transit of Mercury.

    • Year 10,000 problem

    Software that encodes the CE / AD calendar year of a date as a four-character binary-coded decimal will no longer be able to encode the contemporaneous date.
