Estelle Reel Day is not a widely recognized or celebrated national day in the United States, and as such, it does not have established traditions or activities that people engage in on this day. Estelle Reel (1862–1955) was an educator who became one of the first women to hold a major political office in the United States when she was appointed as Superintendent of Indian Schools by President William McKinley in 1898.

While Estelle Reel Day does not have a specific date set aside for commemoration or celebration, her contributions to education and the advancement of women in government service are occasionally remembered and discussed among historians and educators, particularly those with an interest in women's history.

Since there are no known national observances or events dedicated to Estelle Reel Day, there is no standard way that people mark this day. Those who wish to honor her legacy might do so by researching her life, educating others about her achievements, or advocating for continued progress in the areas of education reform and gender equality within public service.
