National Science Appreciation Day is observed in the U.S. every March 26. Established in 2022 by the Center for Inquiry (CFI), this day commemorates the announcement of the successful testing of the first effective polio vaccine by Dr. Jonas Salk in 1953. The day highlights the importance of scientific advancements in improving quality of life and combating pseudoscience. It is part of the ScienceSaves campaign, which aims to increase appreciation for science through storytelling. Participants can engage by sharing personal stories related to science on social media, reading about scientific achievements, visiting museums, or advocating for official proclamations of the day in their states. As of 2025, several states, including Arizona, Florida, and New York, have issued official proclamations recognizing National Science Appreciation Day.
