National Play Outside Day is observed in the USA on the first Saturday of every month, with the next celebration occurring on January 3, 2026. This unofficial holiday was founded in 2011 by Rhonda D. Abeyta and Aaron Wiggans, who aimed to encourage children and families to prioritize outdoor play amidst a decline in such activities due to increased screen time and other modern distractions. The day serves to promote the numerous benefits of outdoor play, including improved physical fitness, social skills, and a connection to nature. Families are encouraged to engage in various outdoor activities, such as sports, hiking, picnicking, and exploring local parks. Participants are also invited to share their experiences on social media using the hashtag #NationalPlayOutsideDay to inspire others to join in the celebration.
