The Georgian Orthodox Church celebrates St. Nino Day on June 1 - the day of arrival of the holy Equal-to-the-Apostles Nino, enlightened by the light of the Gospel teaching. Saint Nino entered Georgia with a cross of vine wrapped around her hair.

On June 1, in 319, St. Nino arrived in Georgia, and in 323, Christianity was declared as the state religion of the whole country.

A festive church service will be conducted at Sioni Cathedral in Tbilisi by Catholicos-Patriarch of All Georgia, His Holiness and Beatitude Ilia II.
