21st century[edit]









22nd century[edit]


  • 2100: On March 14 (which will be February 29 in the Julian calendar), the difference between the Julian calendar and the Gregorian calendar reaches 14 days. Since 14 is divisible by 7, this will be the first time in history since its inception that the Gregorian calendar has the same day of the week for each day of the year as the Julian calendar. This will last until February 28, 2200 of the Gregorian Calendar.
  • Polaris appears furthest North. Polaris's maximum apparent declination (taking account of nutation and aberration) will be 0.4526° from the celestial north pole, on 24 March 2100.[4]
  • 2100 will not be a leap year since it qualifies as a century year not divisible by 400.
  • 2103: Per an agreement between the National Archives and Caroline Kennedy, the jacket Jackie Kennedy wore on the day John F. Kennedy was assassinated cannot be displayed in public until this year.[5]


  • 2110: According to Extreme Engineering from discovery channel, The proposed Japan mega project, the Shimizu Mega-City Pyramid could be completed at this time.
  • 2113: August will be the first time Pluto reaches aphelion since its discovery.
  • 2114: Sedna overtakes Eris as the farthest known spheroid orbiting the Sun.
  • 2117: December 10–11 Transit of Venus.





  • 2150: June 25: Solar eclipse of 7 min 14 s, Solar Saros 139.[7]
    Exceeding 7 minutes of totality, this will be the first time this has happened in 177 years; the last one occurred on June 30, 1973.[8] when the Concorde prototype followed the totality spot during 73 minutes.


  • 2160: March 17 – Unless changes are made as to when Easter can be observed, this particular March 17 will fall within Holy Week for the first time since 2008 and fall on the same day (Monday) as it did in that year, likely requiring the movement of the Feast of Saint Patrick's Day to another date.[9]
  • 2168: July 5: Solar eclipse of 7 min 26 s, saros 139.[10]


  • 2170: Triple conjunction MarsJupiter.
  • 2174: The second full orbit of Neptune around the sun since its discovery in 1846.
  • 2177: "First Plutonian anniversary" of the dwarf planet's discovery, given that Pluto's orbit is just under 248 Earth years.


  • 2185: Triple conjunction MarsSaturn.
  • July 16, 2186 : Solar eclipse[11] of 7 min 29 s (very close to the theoretical maximum), Saros 139,[12] "crowning" this series.
    This is predicted to be the longest eclipse during the current 10,000 year period, from 4000 BC to AD 6000 (eclipse predictions by Fred Espenak, NASA/GSFC.DEPP).[13]
  • 2187: Triple conjunction MarsSaturn.


23rd century[edit]






  • 2251: On March 4 at 10:52 UTC, Venus will occult Uranus.
  • 2253: On August 1, Mercury occults Regulus (last occultation of Regulus by Mercury was on August 13, 364 BC).
  • 2255: Transit of Venus on June 9.


  • 2265: Return to perihelion by the Great Comet of 1861.


  • 2279: Triple conjunction of Jupiter and Saturn.


  • 2281, 2282: Grand Trine of Uranus, Neptune, and Pluto. This last occurred in 1769 and 1770.
