International Women's Day 2010: History, Facts And What You Need To Know About IWD

International Women's Day 2010 marks the 100th such day in world history, and it is being celebrated today, March 8, 2010.

The official International Women's Day Web site notes the following about the occasion:

International Women's Day (8 March) is a global day celebrating the economic, political and social achievements of women past, present and future. In some places like China, Russia, Vietnam and Bulgaria, IWD is a national holiday.

Every year, there is a theme to the day. The theme for International Women's Day 2010 is Equal "rights, equal opportunities: Progress for all."

The United Nations has given its full support to International Women's Day and it fights for women's rights as a major global issue.

Nicholas Kristof articulated three ideas for raising women's status around the world in a New York Times column today.

In 1910, the first international women's conference was held in Copenhagen and countries around the world began celebrating the event annually beginning the following year.
