International Astronomy Center: Wednesday, June 28, 2023, the first day of Eid Al-Adha in most countries

<p style=";text-align:left;direction:ltr">Weather of Arabia - the International Astronomical Center - Most countries of the Islamic world will investigate the crescent of the month of Dhul-Hijjah on Sunday, June 18, 2023 AD, corresponding to Dhu al-Qi`dah 29 1444 AH, and on that day, seeing the crescent is hardly possible using the telescope from the center and west of the Islamic world, and therefore it is expected that it will be Monday, June 19, is the first day of the month of Dhu al-Hijjah in many countries, and Tuesday, June 27 is the stand of Arafah, and Wednesday, June 28 is the first day of Eid al-Adha.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> With regard to the position of the crescent on Sunday, June 18 in some Arab and Islamic cities, the surface calculations for the crescent at sunset are as follows: In Jakarta, the moon sets after 07 minutes of sunset, and its age is 6.5 hours. In Abu Dhabi, the moon sets 29 minutes after sunset, and its age is 12.4 hours. Vision in Jakarta and Abu Dhabi is not possible even using a telescope. In Riyadh, the moon sets 31 minutes after sunset, and it is 13 hours old. In Amman and Jerusalem, the moon sets 37 minutes after sunset, and its age is 13.8 hours. In Cairo, the moon sets 36 minutes after sunset, and it is 14 hours old. In Rabat, the moon sets 44 minutes after sunset, and its age is 16.2 hours. Visibility in Riyadh, Amman, Jerusalem, Cairo and Rabat is possible using a telescope only, although it is difficult in the east and the middle, and requires very clear skies to enable vision.<br /></p><p style=";text-align:left;direction:ltr"> In order to know the meanings of these numbers, it should be noted that the minimum duration of the crescent that could be seen with the naked eye was 29 minutes, while the minimum age of the crescent that could be seen with the naked eye was 15 hours and 33 minutes. Related to other factors such as its angular distance from the sun and its distance from the horizon at the time of observation.<br /></p><p style=";text-align:left;direction:ltr"> Contrary to what is common, many Islamic countries rely on their local vision to determine the beginning of the month of Dhu al-Hijjah and Eid al-Adha, and do not follow any other country, and among these countries: Malaysia, Indonesia, Brunei, India, Pakistan, Bangladesh, Iran, the Sultanate of Oman, the Kingdom of Morocco, Mauritania and Turkey, and most non-Islamic countries Arabic in Africa. And given that seeing the crescent on Sunday, June 18, is not possible by any means from the east of the Islamic world, and it is not possible on that day with the naked eye from the Islamic world, it is expected that some of the previous countries will announce that Tuesday, June 20 is the first day of the month of Dhu al-Hijjah, and that it will be Thursday. June 29 is the first day of Eid al-Adha in these countries.<br /></p><p style=";text-align:left;direction:ltr"> To learn about the results of observing the crescent, you can visit the website of the Islamic Project for Observing the Crescent of the International Astronomy Center on the Internet at the address <a href="http://www.AstronomyCenter.net">www.AstronomyCenter.net</a> , as the project was established in 1998 AD and currently includes more than 1,500 members of scientists who are interested in observing the crescent and calculating calendars. This project encourages those interested in different countries of the world to investigate the crescent and send the results of their observations to the project through its website, where it is published successively after being audited and scrutinized.<br /></p><p style=";text-align:left;direction:ltr"> <strong>The attached map shows the extent to which the crescent can be seen on Sunday, June 18 from all regions of the world, so that:</strong></p><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"> Seeing the crescent is impossible from the areas in the red color because the moon sets before sunset or/and because the surface conjunction occurs after sunset.</li><li style=";text-align:left;direction:ltr"> Seeing the crescent is not possible either with a telescope or with the naked eye from the uncolored areas.</li><li style=";text-align:left;direction:ltr"> Seeing the crescent moon is only possible using a telescope from the areas in blue.</li><li style=";text-align:left;direction:ltr"> Seeing the crescent is possible using the telescope from the areas located in the pink color, and it is possible to see the crescent with the naked eye in the case of complete clearness of the atmosphere and monitoring by an experienced observer.</li><li style=";text-align:left;direction:ltr"> Seeing the crescent is possible with the naked eye from the green areas.</li></ul><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="https://www.astronomycenter.net/icop/hej44_1.gif" /></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p>
