• August 1, 2253: Mercury occults Regulus (last occultation of Regulus by Mercury was on August 13, 364 BC).
• June 9, 2255: Transit of Venus.
• 2256 to 2258: Eris will reach perihelion for the first time since discovery.

Social predictions

• 2256: According to estimates made in 2006, the Centralia mine fire, which ignited under the town of Centralia, Pennsylvania in May 1962, may extinguish. The fire is expected to continue burning for at least 250 years as of 2006.
• 2300: The United Nations predicts 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; 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 United Nations predicts 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 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.

Calendric predictions

• 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.

Religious predictions

Judaism

• According to Jewish Calendars, in 2214, Rosh Hashanah will fall on October 6 for the first time.
• 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).
• According to a number of Jewish scholars, the Year 6000 (2240) of the Hebrew calendar is the latest time for the initiation of the Messianic Age.

See Eschatology: Judaism.

• According to Jewish Calendars, in 2260, Rosh Hashanah will fall on September 6 for the last time.
