Ada Lovelace Day is celebrated on the second Tuesday of October to honor the contributions of Ada Lovelace, one of the first computer programmers, and to highlight the achievements of women in STEM (science, technology, engineering, and mathematics). The day encourages people to learn about Lovelace's work, particularly her collaboration with Charles Babbage on the Analytical Engine, and her visionary ideas regarding computing's potential beyond mere calculations. Observers often engage in activities such as workshops, lectures, and "Wikipedia edit-a-thons" to improve the representation of women in STEM online. The celebration aims to inspire future generations of women to pursue careers in these fields by showcasing role models and their accomplishments. Ada Lovelace Day was founded by Suw Charman-Anderson, who sought to address the invisibility of women in the tech world.
