National Guild Day is observed in Iran every June 22, marking the 1st of Tir in the Iranian calendar. This official professional holiday highlights the significant role of guilds in the country's economic development and political life. Established to underscore the importance of guilds in creating a competitive market, the day features various conferences and events that discuss critical guild-related issues. The activities of guilds and trade unions are regulated by the Iranian Chamber of Guilds, which serves to manage the affairs of these organizations and represent their interests to the government. Historically, guilds have influenced Iran's political landscape, exemplified by the Persian Tobacco Protest, which contributed to the Persian Constitutional Revolution. Overall, National Guild Day reflects the government's focus on maintaining strong relations with guilds and trade unions.
