Celebrated on 09/13/2026
Positive Thinking Day, celebrated annually on September 13, encourages people to focus on the bright side of life. Studies show that positive thinking can boost your immune system, reduce stress, and even increase your lifespan by up to 7.5 years.
Positive Thinking Day was founded in 2010 by Kirsten Harrell, a life coach and motivational speaker from the United States. She created the holiday to inspire individuals to adopt a more optimistic outlook and to spread the benefits of positive thinking. The date, September 13, was chosen arbitrarily to kick off the fall season with a positive mindset.
Since its inception, Positive Thinking Day has grown beyond personal practice into a global movement. Social media campaigns, workplace wellness programs, and educational workshops now promote the day. People celebrate by journaling affirmations, performing acts of kindness, and engaging in mindfulness exercises. Many organizations host events focusing on mental health and resilience.
