National Day Calendar is a couple of individuals who had an idea to research all the unique National Days and post our findings on one website. After a couple of years, we have completed that project although we are still researching the history of a few of the days. We are humbled by the fact that so many people follow us including many in the media. The site has been a hobby. However, as the site becomes increasingly more popular, it is becoming a job. Our mission is to provide information and entertainment to our followers through the daily articles we post.
