Clean Monday, or Sarakosti, has evolved beyond its religious roots, becoming a significant seasonal cycle for grocery retail and the food service industry. This period is now seen as a 'Little Easter' for many food categories, showcasing increased consumer demand, the introduction of new products, extensive promotions, and thematic marketing campaigns that drive sales in the first quarter of the year. During Clean Monday, consumers notably shift their spending habits, moving away from meat and dairy towards categories such as legumes, rice, frozen and fresh vegetables, seafood, traditional spreads, plant-based proteins, and confectioneries like halva and tahini. Market analysts report that sales of frozen seafood, for instance, see remarkable double-digit percentage increases compared to regular months, reflecting consumers' adaptation to the fasting practices of this period. The implications of this trend suggest a strengthening in the business for both supermarkets and eateries, as they capitalize on the growing demand for fasting-compatible foods. Retailers are increasingly investing in targeted campaigns to highlight these offerings, which not only meet consumer needs but also stimulate economic activity. This seasonal shift showcases the interconnectedness of cultural practices and consumer behavior, solidifying Clean Monday's position as a pivotal time for the Greek economy.
