The Bulgarian folk tradition transforms the period between July 15 and 17 into a sacred time interval known as the Hot Days. This interval, marked by the Orthodox days of Saints Cyril and Julita and Saint Marina, possesses deep symbolism and ritual practices.

A central moment in the festive cycle is July 16, when specific ceremonial actions are performed. Local communities extinguish existing home fires and reignite them, preferring twins to perform this symbolic activity. The subsequent ritual jump through the flames is viewed as a magical act to guarantee health.

Folk wisdom connects the temperature during the Hot Days with the intensity of the upcoming winter. Beliefs emphasize that the hotter these days are, the colder the winter will be. The main goal of the ceremonies is to provide protection from drought and stimulate agricultural fertility.

These archaic practices continue to exist in settlements with preserved traditional culture, representing a unique synthesis between Christian and pagan elements. The Hot Days demonstrate the deep connection between Bulgarian communities and the natural cycle.
