In the Buddhist religion there are many deities that are venerated throughout the year. March 26th is the date that Kuan Yin’s Birthday is celebrated on. Known as the Goddess of Mercy, childless couples will go to the temple in hopes to change their situation. Kuan Yin is considered one of the most important of the deities and actually has three separate birthdays that are celebrated through out the year.
Unfortunately, there is much too much that I do not know about the religion and am afraid that I may say something completely wrong so chose to leave it there.
