Substitute Senate Bill No. 1519, now Public Act No. 25-59, amends section 10-29a of the general statutes to designate various days, weeks, and months for specific observances in Connecticut. The bill introduces new proclamations by the Governor, including February 8 as Scouting America Day, February 14 as Neurofibromatosis Awareness Day, and the month of April as Connecticut Native Plant Month, among others. Additional observances include April 11 as Parkinson's Awareness Day, April 26 as Tuskegee Airmen Day, and May as Brain Tumor Awareness Month. The bill also establishes days for recognizing local journalism, indigenous women and children, and various health conditions throughout the year.

Furthermore, the bill designates June 1 as Barber Recognition Day, June 12 as National Women Veterans' Recognition Day, and July as Uterine Fibroid Awareness Month. It continues with proclamations for Lobster Roll Day in September, Varian Fry Day in October, and November as Veterans' Month and Epilepsy Awareness Month. Lastly, it recognizes Diwali on the fifteenth day of Kartik in the Hindu lunar calendar. The bill does not include any deletions from current law, focusing solely on the addition of these new observances.
