Eid ul-Adha is expected to be observed on May 27, 2026, in Saudi Arabia [1].
As one of the most significant holidays in the Islamic calendar, the timing of the festival dictates the schedule for millions of pilgrims and worshippers globally. Because the date relies on the lunar calendar, astronomical predictions serve as a guide until official sightings are confirmed.
In Saudi Arabia, the projected date for the holiday is Wednesday, May 27, 2026 [1]. This date is based on astronomical calculations and the anticipated sighting of the Zil-Hajj moon [1]. The lunar cycle determines the start of the festival, which commemorates the willingness of Ibrahim to sacrifice his son as an act of obedience to God.
Other regions may observe the holiday on different days due to varying moon sighting protocols. In areas such as India and Pakistan, the expected date is May 27 or May 28, 2026 [2]. The final determination in these regions often depends on local committees, such as the Ruet-e-Hilal Committee in Pakistan [2].
These variations occur because different countries follow different criteria for confirming the new crescent moon. Some regions rely strictly on astronomical data, while others require a physical sighting by a certified observer. This often results in a one-day difference in the start of the festivities across the Muslim world [2].
Preparations for the holiday typically include the purchase of livestock for Qurbani, the ritual sacrifice. The timing of the moon sighting is critical for coordinating these logistics, and the accompanying prayers [2].

The discrepancy between the Saudi Arabian date and other regions highlights the ongoing tension between astronomical calculation and traditional sighting methods. While calculations provide a predictable window for travel and commerce, the religious requirement for a physical sighting means that official confirmation will not occur until the moon is actually visible in the sky.
