In Muslim cultures, which Eid is also called the 'Big Eid'?

In Muslim cultures, Eid al-Adha is also called the “Big Eid.” The Arabic name al-Eid al-Kabir means “the Greater Eid” or “the Big Festival,” distinguishing it from Eid al-Fitr, often known as the “Lesser Eid” in some regions.

Eid al-Adha begins on the 10th day of Dhu al-Hijjah, the final month of the Islamic lunar calendar. It coincides with the central days of the annual Hajj pilgrimage and commemorates Ibrahim’s willingness to obey God’s command to sacrifice his son. Islamic tradition generally identifies the son as Isma'il, or Ishmael, while Jewish and Christian traditions identify him as Isaac.

The festival is marked by a special congregational prayer, charitable giving, family gatherings and the sacrifice of livestock where practiced. The meat is commonly divided among the household, relatives and people in need. Eid al-Fitr, by contrast, follows Ramadan and celebrates the completion of that month of fasting; Hajj is the pilgrimage, not an Eid.
