Sham El Nessim in Nationwide
Sham El Nessim falls on the Monday after Coptic Easter and traces back to Shemu, an ancient Egyptian spring harvest celebration now marked by Egyptians of every religion as a national holiday. Families picnic outdoors and eat fesikh, salted fish, lettuce and dyed eggs, foods with symbolic roots stretching back to offerings made to ancient deities.
Sham El Nessim falls each spring on the Monday after Coptic Easter, a scheduling link that traces back to when Egypt was a Christian country under Roman rule, yet the holiday itself is older than that connection and is celebrated today by Egyptians of every religion as a purely national spring occasion rather than a religious one.
