From Wikipedia

The Holy Fire (Greek Ἃγιον Φῶς, "Holy Light") is described by Orthodox Christians as a miracle that occurs every year at the Church of the Holy Sepulchre in Jerusalem on Great Saturday, or Holy Saturday, the day preceding Orthodox Easter. It is considered by many to be the longest-attested annual miracle in the Christian world. It has been consecutively documented since 1106 A.D., with previous references being sporadic. The ceremony is broadcast live in Georgia, Greece, Ukraine, Russia, Romania, Belarus, Bulgaria, Cyprus, Lebanon and other Orthodox countries like Egypt. Furthermore, the Holy Fire is brought to certain Orthodox countries, such as in Georgia, Greece, Russia, Belarus, Cyprus, Serbia, Montenegro, Bulgaria, Romania, Moldova, Ukraine, Syria, Lebanon, Jordan and Macedonia, every year by special flights, being received with honors by state leaders at the respective airports.
