When is Eid al-Adha?
In 2026, Eid al-Adha falls on Wednesday, May 27, 2026. It is classified here as a Indonesian public holiday.
History of Eid al-Adha
Eid al-Adha, known in Indonesia as Idul Adha, is the Feast of Sacrifice. It recalls Ibrahim’s willingness to sacrifice in obedience to God and is connected with the Hajj pilgrimage. The national public holiday brings Muslims together for morning prayer and, where applicable, the distribution of sacrificial meat to neighbours and people in need.
The holiday's social ethic is visible in neighbourhood organisation. Mosques and committees register donated animals, apply health and animal-welfare guidance, organise slaughter and package shares for distribution. Families may donate without personally undertaking the rite, and Indonesian scholars and authorities publish practical rules each year. Customs and dishes differ across the archipelago; the common emphasis is worship and equitable sharing rather than a single feast menu.
The 2026 SKB schedules Idul Adha 1447 H for Wednesday, May 27, subject to the Minister of Religious Affairs' final determination. Thursday, May 28 is separately listed as cuti bersama and canonicalised to this guide. The leave day is not a second religious holiday and private-sector implementation is decided by employers. Essential services and banks publish schedules, while future Gregorian dates must not be copied mechanically from an overseas lunar calendar.
How Eid al-Adha is observed
A nationwide national public holiday scheduled for May 27 in 2026, followed by separately regulated collective leave on May 28. The shown civil date is a planning estimate. Indonesia’s annual Joint Ministerial Decree and the Ministry of Religious Affairs’ announcements take precedence.
