This page presents a table of key Moon events — apogees, perigees, and new and full Moons — drawn from our database. We have one table per year for 500 years, from 1800 to 2299. You can see overview statistics from this data on the Eclipse Statistics page.

You can pick the century, decade and year to display from the menu above. You can also switch to Calendar View to see a year calendar with the the Moon events shown in place.

Hover the mouse over an event to see data about the Moon during that event. The graphical icons show when eclipses occur. Note that all dates and times are in UT.

Key to Fields

Full Moon
The moment in the Moon's orbit when it is exactly opposite the Earth from the Sun. From our perspective, the Moon appears completely illuminated at this point. In practice, the Moon will appear full for a day or so on either side of this moment.
New Moon
The moment in the Moon's orbit when it is exactly between the Earth and the Sun. From our perspective, the Moon appears completely dark at this point, but in any case it is too close to the Sun to be seen. In practice, the Moon will be invisible for a day or so on either side of this moment.
Perigee
The moment in the Moon's elliptical orbit when it is closest to the Earth.
Apogee
The moment in the Moon's elliptical orbit when it is farthest from the Earth.
Sun/Moon Distance
The distance from the centre of the Earth to the Sun/Moon, in km. The percentage figure represents how this distance compares to the average.
Sun Size
The angular diameter of the Sun, in degrees. The percentage figure represents the diameter of the Sun compared to the average.
Moon Size — Geo
The angular diameter of the Moon, as it would be seen from the centre of the Earth ("geocentric"). This is essentially the same size that you would see if the Moon was on the horizon, for example at the start or end of a solar eclipse. The percentage figure represents the diameter of the Moon compared to the average geocentric diameter.
Moon Size — Zenith
The angular diameter of the Moon, as it would be seen from directly beneath it; that is, when it is directly overhead. This is larger than the geocentric size, as you are closer to the Moon by half the diameter of the Earth. The percentage figure represents the diameter of the Moon compared to the average zenith diameter.
Moon Magnitude
The magnitude of the Moon. Magnitude is a measure of an object's brightness, used by astronomers. It uses a logarithmic scale, and counts backwards — smaller numbers, even down to negative numbers, indicate brighter objects. So, an object of magnitude -13 is 2.5 times brighter than an object of magnitude -12. Magnitudes shown here do not take account of the phase of the Moon; they represent what you would see if the Moon was full. The percentage figure represents the actual brightness of the Moon compared to its average brightness.
Eclipse
If an eclipse occurs in conjunction with the given Moon event, it is displayed below the data row. Click on the eclipse name to go to the Eclipse's page. The angular diameter of the Moon at the place and time of maximum eclipse will also be shown here. This can be quite different to the Moon at the moment of New or Full Moon, as the place and time of maximum eclipse do not exactly match the place and time where the full Moon is exactly overhead. The percentage figure represents the diameter of the Moon compared to the average maximum eclipse Moon diameter.
