National Customer Day, or Hari Pelanggan Nasional, is observed in Indonesia every September 4. Established in 2003 by entrepreneur Handi Irawan Djuwandi and supported by state-owned enterprises and the government, this holiday emphasizes the importance of customer relations and recognizes employees who interact directly with customers. Activities typically include seminars, webinars, parades, contests, and award ceremonies, aimed at celebrating those who process orders, provide assistance, and resolve complaints. The holiday serves as a reminder for businesses to prioritize customer satisfaction and continuously meet their customers' evolving needs. It is distinct from National Consumer Day, which is celebrated on April 20 and focuses on consumer rights. National Customer Day encourages companies to foster trust and loyalty through exceptional customer service.
