Seputarkarawang.com - Karawang, BMKG has released a prediction for the position of the new moon that determines the beginning of the month of Zulhijah 1447 H, which is an important reference in determining Eid al-Adha or Eid al-Haji. Based on data from the official BMKG website on Tuesday (5/5/2026), the geocentric conjunction or ijtima' time will occur on Sunday, May 17 2026. Geocentric conjunction itself is an event when the moon's ecliptic longitude is the same as the sun's ecliptic longitude and the observer is assumed to be at the center of the Earth.BMKG explained that the height of the crescent moon at sunset on May 17 2026 in Indonesia, it ranges from 3.29 degrees in Merauke, Papua, to 6.95 degrees in Sabang, Aceh. Furthermore, the elongation angle at sunset on the same day ranges from 8.91 degrees in Merauke, Papua, to 10.62 degrees in Sabang, Aceh.As a reference, Indonesia uses the MABIMS (Minister of Religion of Brunei, Indonesia, Malaysia and Singapore) criteria in determining the new moon. Based on these criteria, the hilal is declared observable if it has a height of at least 3 degrees and an elongation angle of at least 6.4 degrees. Based on this data, the BMKG stated that astronomically, the rukyat hilal determining the beginning of the month of Zulhijah 1447 H was carried out after sunset on May 17 2026. For parties who apply the reckoning method, this criterion has also met the specified threshold.
The initial determination of Zulhijah 1447 H is directly related to the determination of the Eid al-Adha holiday which is celebrated every 10th of Zulhijah. The government will usually set this date officially through an Isbat Session held by the Indonesian Ministry of Religion.If we refer to these calculations, 1 Zulhijah 1447 H is predicted to fall on Monday, 18 May 2026. Thus, Eid al-Adha or 10 Zulhijah 1447 H is predicted to fall on Wednesday, 27 May 2026.The impact of this national calendar prediction Of course, it will also be felt directly by the community and local government in Karawang Regency, West Java. Muslims in Karawang can start preparing to welcome the sacrificial services, Eid al-Adha prayers, and social gathering activities that usually characterize the Idul Fitri Haji celebration.However, the certainty of the date for Eid al-Adha celebrations in Karawang Regency must still wait for an official announcement from the Isbat Session of the Ministry of Religion. The Karawang Regency Government and related officials are advised to continue monitoring this decision so that coordination of the implementation of sacrificial services and distribution of sacrificial meat to local residents can run smoothly.
