When the moon orbits the earth, half of the moon's face will be illuminated. Various shapes of moon that can be seen from the earth are called phases of the moon. Repeat every 29.5 days at each stage
Because of Tide Rock, the same half of the moon is always facing the earth. Therefore, the phase always occurs in the same half of the moon.
The new moon is because we can not see the moon because we are observing half of the moon we are not illuminated. When the moon is between the earth and the sun, a new phase of the moon will appear. Eclipse only happens in the new moon
When the moon looks like a new moon, crescent moon increases every day ("wax"), a new moon waxing. This stage is usually only seen in the west
The month (or half a month) of the first quarter is half of the month visible after the crescent burning phase. The week following the new moon
More than half of the lit part of the moon is seen, and as the shape increases daily ("wax"), the waxy moon appears. The stage at which the wax swelling has occurred occurs between the first quarter and the full moon phase
The full moon is the entire illuminated part of the moon we can see. The full moon occurs when the moon is on the other side of the earth opposite the sun. Lunar eclipse occurs only at full moon
When more than half of the moon is illuminated and the shape is shrunk by day ("attenuation"), the disappearing moon appears. A fading bulge phase occurs between the full moon and the third quarter
The month (or half a month) of last month seems to be half of the month since the phases of the moon gradually weakened.
The moon looks like a new moon, and the crescent moon decreases every day ("weakens").
The second full moon of the calendar month is often called "blue moon" and it occurs approximately every three years. The expression "once entered into Blue Moon" means what does not happen frequently (such as blue moon). [1] [2]
The Roman calendar was originally based on the first three stages of the month and counts the number of days. Rather than being based on the concept of the week, it was based on the stage of the moon. The new moon will fall on the day of Kalends, the first quarter of the month will be the day of Nones, and Ides will fall on the full moon day. When the Romans decided the length of the moon they also decided the day of Ide. The month (most) in March, May, July and October is 31 days, Ides is 15 days. This is the thirteenth time of the other month. The number of days of Ides from Ides to Ides is not changed for 8 days, but the number of days from Kalends to Nones is 4 or 6 days, during the Kalends period 16 to 19 days from Ides to the next month have passed
In the early king, the length of the moon of Rome was the same as the cycle of the moon. Each month is divided into sections that end in one of the first three stages of the month. New, first quarter, or all. All these days are based on one of three moon phase names, Kalends, Nones, or Ides. At that time, Panax (priest) was assigned to observe the sky. When he first saw a thin crescent moon he shouted the new moon and announced that it started next month. Centuries later, the Romans called the first day of the month from Latin Calais as Kalendae or Kalends (solemnly announced and called). A Word calendar derived from this customization
