Moon 13 Ramadan raises controversy on social networking sites

The advent of the moon of Ramadan in full on Saturday, 13 Ramadan, sparked controversy among the pioneers of social media, and questions about the accuracy and accuracy of astronomical calculations of the vision of the moon.

Ibrahim Al Jarwan, member of the Arab Union for Astronomy and Astronomy, told Emirates Al-Youm that the moon's appearance on Saturday (13 Ramadan) is a natural phenomenon where Arabs know the white days as the night of 13, 14 and 15 of the lunar month. , And the fact that the full moon in any of them is permissible.

According to astronomical calculations, the middle of the lunar month was at 11:11 am after the middle of last night, ie, with the beginning of the day of May 19, stressing that the completion of the moon on 13 Ramadan has nothing to do with the health of the vision at the beginning of the month, The moon's appearance is complete because of the ignorance of astronomical matters.

The moon (Al-Badr) on Saturday night is the so-called blue moon (of course, its color is not ordinary blue), and its blue name is attributed to the folklore of farmers in North America and northwestern Europe.

Al-Jarwan said that the blue moon or the blue moon is a term used to indicate additional completeness of the moon, either completing the third moon's moon in the chapter of the four-year seasons of the Moon. Or when the inhabitants of the earth experience one month of joint assessment with two full moons, the phenomenon is called the "blue moon".

It is said that the separation is three months and it is normal to show the full moon 3 times, but the moon may appear full moon sometimes 4 times like this spring, where four cases appear in the moon full moon and this third case and called the blue moon, the other concept of the blue moon is When the full moon appears twice in one calendar month, if the full moon appears at the beginning of the Gregorian month (the first two days of it) it may also appear in the last month of the Gregorian calendar (the last two days) and the other is the blue moon. two years and half .
