In 2011, Dr. Dain Heer wrote a book called Being You, Changing the World. The book is an innovative toolbox for the seekers of the world and has become a bestseller over the years. Today, it translates to over 17 languages, turning into a series of seminars and workshops with over 100 trained facilitators.
In 2021, National Day Calendar and Dr. Dain Heer formed a working relationship to create International Being You Day. This International Day was originally observed on May 22, 2021, but changed to June 22 in 2023. Starting in 2024, International Being You Day will be celebrated on June 22 each year.
