National Pay Back a Friend Day is observed on October 17 and focuses on strengthening friendships by encouraging individuals to settle financial debts with friends. It aims to alleviate the stress associated with monetary obligations and promote open conversations about money, which can help mend strained relationships. The day is celebrated across the United States and encourages actions such as using mobile payment apps to repay debts, inviting friends for meals, giving thoughtful gifts, writing notes of gratitude, and planning fun outings together. These activities not only help clear financial misunderstandings but also reinforce trust and enhance personal happiness. The initiative was founded by Bank of America to address the financial strains that can damage friendships.
