Eid-ul-Adha is significant also because the day marks the culmination of Haj, pilgrimage made to Kaaba in Mecca. The rites of Haj are performed over 5-6 days, re-enacting the events carried out by Prophet Abraham. Haj marks the end of the Islamic calendar and is the fifth pillar of Islam. Everybody who can afford and is fit to make the journey is mandated to do so.
