_______________________________________

One of the aims of the Institute of World Culture is "to honour through appropriate observance the contributions of men and women of all ages to world culture."  This calendar offers just a taste of the rich diversity of those contributions.  We attempt to substantiate the dates but dates can vary depending on the calendar in use when the date was determined or if the date is based on the Julian or Gregorian calendar. Certain dates are the best estimate of scholars as the original dates are lost in history. The intention of this calendar is to show the great diversity and excellence in the contributions of men and women of world culture and in this case the dates are secondary.  You can click on a particular month, listed in the column on the left, or scroll down to see listings for the entire year.  This calendar is a work in progress so please let us know if you have contributions or corrections by contacting donna@worldculture.org

"Be an opener of doors for such as come after thee." – Ralph Waldo Emerson

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.” – George Bernard Shaw
