Sunday, August 28, 2287: Closest approach between Mars and Earth since Wednesday, August 27, 2003.
In 2288, the planetoid Quaoar will have completed one orbit of the Sun since its discovery in 2002, which, based upon current orbital measurements, gives it a period of 286 Earth years.
2300: The United Nations projects that life expectancies in most developed countries will be 87–106 years, and slowly rising, though rising more slowly than before. However, these projections also show that life expectancies in poor countries will still be less than in rich countries in 2300, in some cases by as much as 20 years, and the UN itself mentioned that gaps in life expectancy so far in the future will likely not exist, especially since the exchange of technology between rich and poor countries and the industrialization and development of poor countries will cause their life expectancies to fully converge with those of rich countries long before that point, similarly to how life expectancies between rich and poor countries have already been converging over the last 60 years as better medicine, technology, and living conditions became accessible to many people in poor countries. The UN has warned that these projections are uncertain, and caution that any change or advancement in medical technology could invalidate their projections.
2300: The U.N. projects the world population in 2300 to be about 10 billion, but any changes in future birthrates or in projections of future life expectancy could invalidate those projections as well.
2300: Google's master plan to index all the world's information and make it searchable could be achieved, according to Eric Schmidt.
2300: No new PESEL numbers can be allocated, the number required by law for all Polish citizens.
Unless changes are made in the religious calendar, in 2285, the Western Easter will fall on March 22 for the first time since 1818, the earliest possible date on which Easter can occur.
According to one Jewish interpretation of creation, Adam was created in 3761 BC. It will have been 6,000 years since then in 2239, thereby initiating a spiritual Sabbatical on a global scale lasting a thousand years (the 7th Millennium on the Hebrew Calendar). On the same basis, the common assumption in 16th-century Europe was that the current world would end in 2242. Even Nostradamus's well-known prediction that his prophecies would run out in 3797, first made in 1555 (see Nostradamus source-list), would seem to fit this tradition (3797 – 1555 = 2242).
Starhunter, the events take place across the latter half of the 23rd century, the 1st season in 2276–2286 and the 2nd season in 2300.
Red Dwarf, parts of the series may be set in the 23rd century, evidenced by Lister stating that he is "an enlightened 23rd century guy." However, other episodes imply Lister is from the 21st century or 22nd century, and most of the series is set about 3 million years later.
2270: The supposed year in which Will Robinson, Dr. Smith and the Robot slept until in the "Flight Into the Future" episode of Lost in Space. It turned out to be an illusion caused by an alien creature.
