Amid Trump's second term, Women's March organizers across the U.S. are prompting people to unite with calls to action.

The day, celebrated annually on March 8, is dedicated to the advancement of women and equality for all genders. The holiday was first celebrated on March 19, 1911, in Austria, Denmark, Germany, and Switzerland, with more than one million men and women attending rallies, the website says.
