Each February 1, Black History Month commences, USA

And I think it's a very good idea.
And, given my son Remy, a man of 21 in less than a year, I think we need one in Australia.

Black History Month commences, United States of America

From Wikipedia: Black History Month is celebrated annually in the United States in the month of February. Black History Month originated as 'Negro History Week', the second week in February.

This celebration of black history in America was started by African-American historian Dr Carter G Woodson, who wanted to bring national attention to the large contribution of African-Americans to the history of their country, in 1926. Woodson chose February as black history month because in this month Abraham Lincoln, Frederick Douglass, and Langston Hughes were born. Some have speculated whether February's status as the shortest and coldest month of the year was a factor in Woodson's choice. History books had barely started covering black history when the tradition of Black History Month was started. At that point, most representation of blacks in history books was only in reference to the low social position they held. Dr Woodson hoped that the week would eventually be eliminated, when African-American history would be fully integrated with American history.
In the United Kingdom, Black History Month is celebrated in the month of October. The official guide to black history month is published by Sugar Media, Ltd., which produces 100,000 copies nationwide.
Criticism
Black History Month sparks an annual debate about the continued usefulness of a designated month dedicated to the history of one race. Critical op-ed pieces have appeared in the Cincinnati Enquirer and USA Today.
Many black radical/nationalist groups, including the Nation of Islam, have criticized Black History Month.
In the December 18, 2005 episode of 60 Minutes, actor Morgan Freeman criticized Black History Month. "I don't want a black history month. Black history is American history." Freeman believes that racism will persist as long as individuals continue to identify themselves by their race.
