Professional Engineers Day is celebrated on August 5 to recognize the contributions of licensed professional engineers in various fields such as transportation, energy, and manufacturing. Founded by Tim Austin, a licensed professional engineer and former president of the National Society of Professional Engineers, this day aims to raise public awareness about the importance of engineering excellence. The first observance of Professional Engineers Day occurred in 2016. Typical customs include showing appreciation to professional engineers through gestures like taking them out for a meal, sending cards, or organizing team celebrations at engineering firms. Additionally, it encourages non-engineers to learn about engineering feats and the impact of engineers on everyday life.
