Phases of the Moon and Percent of the Moon Illuminated
Pictures, animations, and brief comments.

  • Naval Observatory Astronomical Applications Department Phases of the Moon and Percent of the Moon Illuminated Note: For Moon phase information specific to a particular date, see , or in Data Services

  • From any location on the Earth, the Moon appears to be a circular disk which, at any specific time, is illuminated to some degree by direct sunlight

  • Like the Earth, the Moon is a sphere which is always half illuminated by the Sun, but as the Moon orbits the Earth we get to see more or less of the illuminated half

  • During each lunar orbit (a lunar month), we see the Moon's appearance change from not visibly illuminated through partially illuminated to fully illuminated, then back through partially illuminated to not illuminated again

  • The phases designate both the degree to which the Moon is illuminated and the geometric appearance of the illuminated part

  • These phases of the Moon, in the sequence of their occurrence (starting from New Moon), are listed below

  • New Moon - The Moon's unilluminated side is facing the Earth

  • The Moon is not visible (except during a solar eclipse)

  • Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight

    The Date of Easter
    Gives the ecclesiastical rules for setting the date for Easter on calendars,
    differences with astronomical methods, and the current algorythm used to compute ...

  • The usual statement, that Easter Day is the first Sunday after the full moon that occurs next after the vernal equinox, is not a precise statement of the actual ecclesiastical rules

  • The full moon involved is not the astronomical Full Moon but an ecclesiastical moon (determined from tables) that keeps, more or less, in step with the astronomical Moon

  • The ecclesiastical rules are: Easter falls on the first Sunday following the first ecclesiastical full moon that occurs on or after the day of the vernal equinox; this particular ecclesiastical full moon is the 14th day of a tabular lunation (new moon); and the vernal equinox is fixed as March 21

  • The Gregorian dates for the ecclesiastical full moon come from the Gregorian tables

  • In a congress held in 1923, the eastern churches adopted a modified Gregorian Calendar and decided to set the date of Easter according to the astronomical Full Moon for the meridian of Jerusalem

  • The times of the ecclesiastical full moons are not necessarily identical to the times of astronomical Full Moons

  • Inevitably, then, the date of Easter occasionally differs from a date that depends on the astronomical Full Moon and vernal equinox

    Melbourne Planetarium: The Moon

  • About the Moon About the Moon The face of the Moon as seen from the Southern Hemisphere

  • Average Distance from the Earth: 384 400 km (0.0026 AU) Size (Equatorial Diameter): 3475.6 km (0.272 x that of Earth) Mass: 7.35 x 10 22 kg (0.012 x that of Earth) Rotation Period: 27.3 days Temperature: 117°C (sunlit side) -163°C (dark side) Gravity: 1.7 m/s 2 (0.17 x that of Earth) We see the Moon in our northern sky and though it may appear large, especially when seen close to the horizon, our view of the Moon is actually small enough to be covered by your thumb

  • The mass of the Earth and the Moon are similar when compared to the other planets in the solar system, so the Earth and Moon could be said to be companion planets

  • The Moon is thought to have formed when a rogue Mars—sized planet collided with the Earth 4.6 billion years ago

  • Surface The Moon is a rocky object and its surface consists of rock and dust, all of a uniform grey colour

  • The Clementine probe found evidence of water ice at the base of a permanently shadowed crater near the Moon's south pole, known as the South Pole-Aitken Basin

  • Atmosphere The Moon has no atmosphere, so there is no erosion or weathering of surface features

  • Are more babies born at the full moon? No, the full moon does not appear to have any effect on labor

  • In fact, when my first baby was due, the moon was full, but the labor department of the hospital was nearly empty

  • When he was actually born, one week later, at the third quarter of the moon, the hospital was full! Interestingly, it seems that the barometric pressure might be related to when babies are born, with more babies being born after the barometric pressure drops, during a big storm, as though a drop in the barometer sometimes triggers labor

  • More questions? Please do not write to me asking me when the full moon is, or anything else that is easily answered simply by looking at the files presented here! Lunar phases for dates in the past or future If you need to know the lunar phase on any particular date, in the past or future, I strongly recommend the use of the US Navy's Virtual Reality Moon Phase Pictures page, which will calculate the phase for you on the fly

    From Sky and Telescope magazine. Explains what it is and when the phenomenon happens.

  • What's a Blue Moon? The trendy definition of 'blue Moon' as the second full Moon in a month is a mistake

  • Olson, and Richard Tresch Fienberg A rising full Moon lights the scene in The Fishing Party, painted by Fitz Hugh Lane after a visit to the coast of Maine in August 1850

  • That month contained a Fruit Moon, according to the Maine almanac's rules

  • Recent decades have seen widespread popular embrace of the idea that when a calendar month contains two full Moons, the second one is called a 'Blue Moon.' The unusual pattern of lunar phases in early 1999 — two full Moons each in January and March, and none at all in February — triggered a groundswell of public interest

  • Countless newspapers and radio and TV stations ran stories about Blue Moons

  • In an article, folklorist Philip Hiscock traced the calendrical meaning of the term 'Blue Moon' to the Maine Farmers' Almanac for 1937

  • But a page from that almanac belies the second-full-Moon-in-a-month interpretation

  • These refer to more than a dozen Blue Moons, and not one of them is the second full Moon in a month

  • The whole system of epacts is based on the Metonic Lunar Cycle (otherwise known as the Cycle of Golden Numbers), and serves to indicate the days of the year on which the new moons occur

  • Consequently, since this month always began with that new moon of which the fourteenth day occurred on or next after the vernal equinox, Christ arose from the dead on Sunday, the seventeenth day of the so-called paschal moon

  • It is evident, then, that an exact anniversary of is impossible except in years in which the seventeenth day of the paschal moon falls on Sunday

  • To secure uniformity of practice, the Council of Nicæa (325) decreed that the Western method of keeping on the Sunday after the fourteenth day of the moon should be adopted throughout the Church, believing no doubt that this mode fitted in better with the historical facts and wishing to give a lasting proof that the Jewish Passover was not, as the Quartodeciman heretics believed, an ordinance of

  • As in the Julian calendar the months had lost all their original reference to the moon, the early were compelled to use the Metonic Lunar Cycle of the Greeks to find the fourteenth day of the paschal moon
