A list of future observable astronomical events.[1] These are by no means all events, but only the notable or rare ones. In particular, it does not include solar eclipses or lunar eclipses unless otherwise notable, as they are far too numerous to list (see below for articles with lists of all these). Nor does it list astronomical events that have yet to be discovered. Some points of the list miss the last date of the events.

1The eclipse of 2045 will be visible from the United States, producing a path from California to Florida. Some parts of Florida are predicted to experience totality for six minutes, the longest in US history.
2Exceeding 7 minutes of totality, this will be the first time this has happened in 177 years; the last one occurred on June 30, 1973,[140] when the Concorde prototype followed the totality spot for 73 minutes.
3Largest total solar eclipse in the 3rd millennium, with a magnitude of 1.08074[141]
4Very close to the theoretical maximum.
5"Crowning" this series. This is predicted to be the longest eclipse during the current 10,000-year period, from 4000 BC to 6000 AD (eclipse predictions by Fred Espenak, NASA/GSFC.DEPP).[142]

7This will be the longest solar eclipse of the 25th century.
8"Crowning" at the top the series.
9First total solar eclipse visible from London since 2151.[143] The width of its path is predicted to be exceptionally wide at its maximum point.

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 ?T, the dates would be about one day earlier. Because of this difference, these dates have no anniversary relation to historical dates and should not be linked to them. Furthermore, they are only astronomical dates, so they are given in the astronomical format of Year Month Day, which allows them to be ordered.

This assumes that these calendars continue in use, without further adjustments.
(Some of these are not astronomical events.)
| Years from now | Gregorian date | Event | |
|---|---|---|---|
| 2077 | Beginning of the 16th century in the Islamic calendar. | ||
| 2100, March 1 | First century non-leap year since 1900. | ||
| 2100, March 14 | 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. | ||
| 2214 | Rosh Hashanah will fall on October 6 for the first time. | ||
| 2239 September 29 | The Year 6000 begins in the Hebrew calendar. | ||
| 2260 | Rosh Hashanah will fall on September 6 for the last time in over 10,000 years. | ||
| 2285 | Unless changes are made in the religious calendar, the Western Easter will fall on March 22 for the first time since 1818, the earliest possible date on which Easter can occur.[158] | ||
| 2800, March 1 | The Revised Julian and Gregorian calendars will differ by a day.[159] | ||
| ≈2750 | 4772 October 13 | The Mesoamerican Long Count calendar, assuming a turnover value of 20 b'ak'tuns, will require a sixth order. | |
| 4909 | The Gregorian calendar will be a full day ahead of the solar year. | ||
| 6009 | The first Strobogrammatic numbered year since 1961. | ||
| 10,000 | The Gregorian calendar will have drifted by about 10 days in relation to the seasons. | ||
| June 10, AD 12,892 | In the Hebrew calendar, due to a gradual drift in relation to the solar year, Passover will fall on the northern summer solstice (it has historically fallen around the spring equinox).[160] | ||
| AD 20,874 | The lunar Islamic calendar and the solar Gregorian calendar will share the same year number. After this, the shorter Islamic calendar will slowly overtake the Gregorian. | ||
| 25,000 | The Tabular Islamic calendar will be roughly 10 days out of sync with the Moon's phases.[161] | ||
| March 1, AD 48,901[162] | The Julian calendar (365.25 days) and Gregorian calendar (365.2425 days) will be one year apart. The Julian day number (a measure used by astronomers) at Greenwich mean midnight (start of day) is 19 581 842.5 for both dates. |
