As the Serb Church uses the Calendrier Julien, the celebration of this festival by the Serb ones currently coincides with the June 28th of the Gregorian Calendrier.

It should be noted that the Catholic church and Roman recently moved Saint-Guy at June 12th, shifting the Roman use of the orthodoxe use.
