        "summary": "The Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) and the National Research and Innovation Agency (BRIN) have forecasted that Eid al-Fitr 1447 Hijriah, or Lebaran 2026, is likely to occur on Saturday, 21 March 2026, based on astronomical data indicating insufficient visibility of the new moon crescent on 19 March. This prediction, which may lead to differing dates with organisations like Muhammadiyah due to varying criteria for moon sighting, highlights the scientific and methodological approaches to determining Islamic holidays in Indonesia. The final government decision will be made at the Isbat Session by the Ministry of Religious Affairs following nationwide reports on crescent observations.",
        "content": "<p>The Indonesian Agency for Meteorology, Climatology, and Geophysics\n(BMKG) and the National Research and Innovation Agency (BRIN) have\nreleased a prediction regarding the determination of Eid al-Fitr 1447\nHijriah, or Lebaran 2026. Based on astronomical data, 1 Syawal 1447 H is\nhighly likely to fall on Saturday, 21 March 2026.<\/p>\n<p>BRIN Senior Researcher Thomas Djamaluddin stated that the moon\u2019s\nposition on Thursday, 19 March 2026, at sunset does not meet the\nvisibility criteria for the hilal (new moon crescent) agreed upon by\nMABIMS countries.<\/p>\n<p>According to the BMKG\u2019s hilal forecast report, at Maghrib on 19 March\n2026, the hilal\u2019s height in Indonesian regions remains very low. In\nMerauke, Papua, the hilal height is recorded at only 0.91 degrees, while\nthe highest position in Sabang, Aceh, reaches 3.13 degrees.<\/p>\n<p>However, another key parameter, elongation (the angular distance\nbetween the moon and the sun), is observed to be only in the range of\n4.54 to 6.1 degrees. This figure is still below the minimum MABIMS\ncriterion, which sets a minimum elongation of 6.4 degrees.<\/p>\n<p>This situation opens the possibility of differing Eid al-Fitr\ncelebration dates in Indonesia. Muhammadiyah, through its Global Unified\nHijriah Calendar (KHGT), has set 1 Syawal 1447 H on Friday, 20 March\n2026.<\/p>\n<p>This difference arises from the use of different criteria.\nMuhammadiyah employs a calculation method that does not require physical\nvisibility of the hilal in Indonesian territory, as long as global\nconditions are met.<\/p>\n<p>BMKG also reminds field observers to be cautious of other\nastronomical objects, such as bright planets near the hilal, which could\nlead to misidentification.<\/p>\n<p>The government\u2019s final decision will be determined at the Isbat\nSession held by the Ministry of Religious Affairs on 19 March 2026,\nafter collecting reports on hilal sighting results from various points\nacross Indonesia.<\/p>",
