Lunar year, lunar month, lunar day
Use the lunar calendar by people began much earlier than the solar calendar. Since ancient times, people lived exactly in accordance with the lunar rhythms, they understood that the effect of the Moon on the Earth is not weaker and perhaps even stronger than the sun. In ancient Rome, after each new moon priests publicly reported beginning of the month, called the date of the lunar phases. Now we live on the solar calendar, in the rhythms of the sun, but the accounting data of the lunar calendar in our daily life is still relevant if we want to feel good about themselves and succeed.
Lunar Year. Earth year lasts 365 days, but it is - the length of the solar year. It was during this time, the Earth makes a complete revolution around the sun. If we lived in the lunar calendar, the year would have lasted 354.36 Earth days - this is the length of the lunar year.
A Lunar Day is the period it takes for the Earth's Moon to complete one full rotation on its axis with respect to the Sun. Equivalently, it is the time it takes the Moon to make one complete orbit around the Earth and come back to the same phase. It is marked from a new moon to the next new moon. Lunar day is longer than a sunny day. Lunar day lasts 24 hours 48 minutes - that is how much time passes from one moon rise to the next. Lunar Days - those that are described in the astrological traditions of the World - are quite different from the familiar calendar days. The First Lunar Day always begins at the moment of the New Moon. Each subsequent day begins at the moment of moon rise in the given location. This means that Lunar Days are location-specific: the moment of moon rise depends on the longitude and latitude of the location and so even if two cities are located in the same time zone (say, New York and Boston), there will be a more or less substantial difference between their Lunar Days.
By the way, scientists who study biological rhythms, found that the human biological clock (property of the brain that allows us to accurately feel the time and wake up at the right time without an alarm clock) “wound up” about 24,5-25 hours, that is more in tune with the rhythms of the moon than the sun. Maybe that's why many people always suffer from a lack of time? It says about them: “He is 24 hours in a day is not enough!” Or maybe they do not have this particular missing lunar hours?
The lunar month is shorter than our usual solar month. In the lunar month of 29.53 Earth days.
Moonlit night (Lunar twenty-four hours) - this time, which runs from sunrise to moon rise. Except for the first lunar day: they start at the time of the new moon, and it does not coincide with the moment of sunrise. End first lunar day, at the time of the next new moon after the rising of the moon. Therefore, the first lunar day can be very short.
Sometimes, in the lunar month of 29 lunar days, and sometimes - 30. Thirties lunar day can also be very short: they do not end with the nearest rising moon, and at the time of the new moon, which can happen between two lunar sunrise. The duration of all other lunar day is about the same.

Critical points of the Moon

In the lunar month, there are four critical points - these are the days of precise phases. They are listed in the calendar.
These days, the moon and sun are at a critical angular distance from each other to form a tight, inharmonious or stress aspects. These are the days of turning points of the cycle.
Two main criticisms of the day - it's a new moon (distance 0 deg) and full moon (distance 180 deg.).
Two intermediate - is growing (in the first quarter) and falling (in the third quarter) squaring the Moon to the Sun. During the 1st and 3rd quarters of the moon is from the Sun at an angular distance of 90 degrees.

The first quarter of the lunar month there is usually 7-8 lunar day; the second - from 14 to 17 lunar day, the third quarter - at 22-23 and night. Fourth Quarter - is the end of one of the lunar month and the beginning of a new one.
Four critical points of the lunar month - according to statistics, during accidents and disasters, disease exacerbation. In these days of internal processes in the human body and psyche are unstable. Any business these days is experiencing a temporary crisis. Folk wisdom warns against making important decisions in the critical days of the moon.
Archetypal waxing Moon is associated with the manifestation in the material sphere, and falling Moon - with the growth of the spiritual. But there is a lunar month, and days that are best suited for the beginning of anything was new.

Moon and the psyche of man
The phases of the moon have a certain effect on the psychoemotional state of people, provoke outbreaks of aggression, somnambulism or insomnia. Scientists conducted a special study. The experts made appropriate conclusions on the results of a large research project, in which a huge amount of statistical data collected due to a large number of people was analyzed. It turned out that the Moon really affects human health and behavior, but it can cope with a mentally strong person. Ie, the Moon can only affect the behavior of the person predisposed to it. "We are talking about those who are pathologically susceptible to all kinds of suggestions, as well as in the whole emotionally unstable and infantile people. Here the moon actually acts very much even on them. On the rest - hardly ", - say the researchers.
Thus, if you feel that you are a mentally stable person, then you can not be afraid of the moon - it is not able to somehow affect your state of health.

What is a Gibbous Moon?
It’s when the Moon is more than half full, but not quite fully illuminated, when you look at it from the perspective of Earth. The reason the light changes has to do with how the Moon orbits the Earth.
The average distance between the Earth and the Moon is about 382,500 km (237,675 miles). As the Moon orbits our planet, the illumination of the Sun changes on its surface. The Moon takes about 29.5 days to go from a new moon to a full moon and then back again. This is called a “synodic period” or sometimes, a “synodic month.”
It’s slightly longer than the “sidereal period” or “sidereal month” (27.3 days) for the Moon to return to the same position relative to the stars. That’s because the Earth is moving at the same time along its orbit of the Sun, requiring the Moon to “catch up” to reach the same illumination, according to NASA.

Supermoon
Did you know that there is a technical, astronomical definition for the term “Supermoon”? Many people use the word to refer to any moon that appears larger than usual, but supermoons are those that are closer to Earth than other full moons.
The moon’s orbit is not a perfect circle around the Earth; rather, it is elliptical. As a result, there will be times when the moon is closer to Earth and times when it is further away. When the moon reaches its closest distance to Earth, it is called perigee – about 225,000 miles (363,300 km). And when perigee coincides with the time of a full moon, it is a Supermoon. According to NASA, a supermoon can appear “14 percent larger and 30 percent brighter” than a regular full moon.

In different sources there are discrepancies in the calculation of the age of the moon. This is due to the fact that the movement of the moon is extremely uneven. Therefore, the accuracy of the formulas for the determination of the lunar day, such a formula Harvey is plus-minus one day.

Hence, the differences in the one day of our lunar calendar with some other calendars. What to do? Do not worry! Remember that the key is to know the phases of the moon and the position of the Moon in the sign of the Zodiac.
But do not forget, the calendar is advisory in nature. When making decisions rely more on themselves.

A lunar calendar is a calendar up to expectation is based about cycles regarding the lunar phases. Because so are barely extra than twelve lunations (synodic months) within a photo voltaic year, the duration about 12 lunar months (354.37 days) is each so often referred in conformity with namely a lunar year.
A frequent simply the lunar calendar is the Islamic calendar or Hijri Qatari calendar. A feature regarding the Islamic calendar is to that amount a year is always 12 months, and the months are not attached along the seasons then go with the flow every solar year with the aid of 11 to 12 days. It comes again to the position it had of bracing in conformity with the photo voltaic year approximately each 33 Islamic years. It is used more often than not for religious purposes, however between Saudi Arabia it is the legitimate calendar. Other lunar calendars frequently consist of greater months delivered each so often in accordance with synchronizing such along the solar calendar.
The oldest acknowledged lunar calendar used to be discovered between Scotland; such dates again in conformity with around 8000 BC.
