Well, whatever. It is still Eid, or the Sacrifice Feast. All Muslims by tradition share food etc with other Muslims to ensure that nobody (the poor and hungry or impoverished) goes without. Traditionally this was usually the sacrifice and sharing out of domestic animals such as chickens or goats (Udhiya) etc, so it is generally a feast of sorts, regardless of whether they were fasting or not during Ramadan.
My daughters play was today, some of the cast were away due to Eid, my daughters friend (a muslim) said they eat lovely food, wear pretty clothes and dance
