Builders' Day is observed in Azerbaijan every April 10 and is an annual professional holiday dedicated to honoring the country's construction workers. Established in 2009 by President Ilham Aliyev, the holiday recognizes the significant contribution of construction professionals to the national economy. The presidential decree for this holiday was signed on December 17, 2009, and the first celebration occurred on April 10, 2010. Unlike many post-Soviet countries that celebrate Builders' Day on the second Sunday in August, Azerbaijan chose this specific date. The day is typically a working day unless it coincides with a weekend. This unique observance highlights the importance of the construction sector in Azerbaijan's development.
