Moon Sighting
When Is Eid Determined?
Eid al-Adha begins on the 10th day of Dhul Hijjah, the twelfth and final month of the Islamic calendar. The date is determined by sighting the new crescent moon (هلال — hilal) after the 29th day of Dhul Qa'dah.
Physical Moon Sighting
The traditional method. Trusted witnesses observe the sky after sunset on the 29th of Dhul Qa'dah. If the crescent is sighted, Dhul Hijjah begins the next day — and Eid al-Adha follows on the 10th. If not, Dhul Qa'dah completes 30 days.
Astronomical Calculation
Modern method used by many Islamic organizations worldwide. Precise astronomical data predicts when the new moon will be visible, allowing dates to be set in advance.

The Celebration
What Is Eid al-Adha?
Eid al-Adha (عيد الأضحى — "Festival of the Sacrifice") is one of the two major Islamic holidays, celebrated by nearly 2 billion Muslims worldwide.
Eid Prayer
Muslims gather for a special communal prayer (Salat al-Eid) in the morning, typically held in large open spaces or mosques. It includes a sermon (khutbah) about gratitude and unity.
Qurbani / Udhiyya
The sacrifice of a sheep, goat, cow, or camel after Eid prayer, commemorating Ibrahim's willingness to sacrifice for the sake of Allah. The meat is traditionally shared with family, neighbors, and those in need.
Family & Community
Families gather for festive meals, exchange gifts, wear new clothes, and visit relatives and friends. Children often receive money or presents (Eidi). It's a day of joy, gratitude, and togetherness.
Completion of Hajj
Eid al-Adha marks the completion of Hajj — the annual pilgrimage to Makkah and one of the five pillars of Islam. Pilgrims gather at Arafah on the 9th of Dhul Hijjah; Eid follows the next day.
The First 10 Days of Dhul Hijjah
مَا مِنْ أَيَّامٍ الْعَمَلُ الصَّالِحُ فِيهَا أَحَبُّ إِلَى اللَّهِ مِنْ هَذِهِ الأَيَّامِ الْعَشْرِ
"There are no days in which righteous deeds are more beloved to Allah than these ten days."
— Sahih al-Bukhari 969
We are in the most blessed days of the year. The Day of Arafah — the 9th of Dhul Hijjah — is the most important day of the Hajj. For those not on pilgrimage, fasting Arafah is highly recommended. Every act of worship, every du'a, every sadaqah during these days carries immeasurable weight.
Make every day count.
