re: Does everyone know why the communists chose March 8th to celebrate Int. Women’s Day?

I am actually leaning more toward this could be plausible based solely on the information provided on the International Women's Day website. I also think the origins of this beyond the date are interesting.

1909- the first National Woman's Day was observed in the US, and it was started by the Socialist Party of America.
1910- Clara Zetkin of Germany proposed the idea of an international women's day. Clara Zetkin was a communist and part of the Communist Party of Germany.
1917- Russian women began to strike on February 23 on the Julian calendar but this is actually March 8 in the Gregorian calendar. The February Revolution in Russia began on the same day.

Before this, it didn't appear that women's days were celebrated on a particular day. For example:
-In America, from 1909 to 1913, it was celebrated on the last Sunday of February
-in 1911 Austria, Denmark, Germany, and Switzerland held it for the first time on March 19
-In 1913, Russia celebrated it on February 23
-In 1914, a march was held in London on March 8

There didn't appear to be a cohesive date for celebrating International Women's Day, so why did they choose March 8? I think its interesting that the IWD history actually goes into detail about the difference between the Julian and Gregorian calendar when describing their role in the revolution. However, based on the information provided on the website, it isn't clear why this date was chosen. By the way, I included a link to their website so you can see for yourself.
