Slava Isusu Khrestu!
This is what I found:
The Procession of the Precious Wood of the Life-giving Cross of the Lord is commemorated by the Church on August 1. It is the first of the three "Feasts of the Savior" in August. (The second is the great feastday of the Transfiguration, and the third is the Translation of the Image Not-Made-by-Hands on August 16.
It became a tradition to carry the wood of the Venerable Cross through the streets of Constantinople for the sanctification of the city starting in the beginning of August. This was done because illnesses were more common in August at that time. On the eve of the feast, it was taken out of the imperial treasury, and laid upon the altar of the Great Church of Hagia Sophia. From this Feast until the Feast of the Dormition of the Most Holy Theotokos, they carried the relic of the Cross, throughout the city in procession, offering it to the people to venerate.
