And the Islamic calendar is a lunar calendar. And the notion of a month, in fact, in English, it comes from the word moon, because it's referring to a full cycle of the moon. Now the end of this month ends with the Eid al-Fitr, which is the festival of breaking the fast, which is considered one of the two major holidays in Islam. Now the fifth pillar of Islam is the notion of pilgrimage to the Kaaba during the 12th month. And it's during a certain period in that 12th month. And then also in that 12th month, you have the second major holiday in Islam, and that's Eid al-Adha, the festival of the sacrifice. And that, once again, is making reference to Abraham and his willingness to sacrifice his son before God stops him.
