On September 14, the Orthodox Church celebrates Krastovden (Feast of the Holy Cross), a holiday that marks a key moment in the agricultural calendar and folk traditions of Bulgaria. For those who make their living from the land, this date symbolizes a transitional stage: in certain regions of the country, it marks the beginning of the grape harvest, while elsewhere, farmers focus all their efforts on preparing for the autumn sowing.

In local beliefs, September 14 is perceived as a kind of boundary, marking the end of summer and the approach of autumn. Around Krastovden, a characteristic change in weather conditions is observed, as nature gradually begins to adjust for the coming cold winter months.

The spiritual essence of the day is entirely dedicated to the cross, which is revered as the central symbol of the Christian faith and the heavy suffering endured by Christ. In accordance with church canon, a strict fast is observed during the holiday, which mandates the total exclusion of meat, eggs, and dairy products from the table.
