Volunteer Recognition Day is celebrated on April 20, 2015. It honors all volunteers who are working on behalf of others without being motivated by financial or material gain. You can celebrate Volunteer Recognition Day by thanking volunteers for their work, involving yourself in a volunteer activity or by donating to a volunteer group.
Volunteering is generally considered an altruistic activity and is intended to promote good or improve human quality of life. In return, this activity produces a feeling of self-worth and respect; however, there is no financial gain. Volunteering is also renowned for skill development, socialization, and fun. It is also intended to make contacts for possible employment.
Many volunteers are specifically trained in the areas they work, such as medicine, education, or emergency rescue. Others serve on an as-needed basis, such as in response to a natural disaster. (With material from: Wikipedia)
