Women's Marches Will Be Held on All 7 Continents

On his first full-day in office, President Trump will get the message that "women's rights are human rights"—or that's the hope of some 400,000 people expected to attend the Women's March in Washington on Saturday. Here's what to know about the event:

• The principles of it are laid out here, and they touch on a lot more than women's rights, including workers' and immigrant rights and environmental justice.
• ABC News explains how a Hawaiian grandmother started the idea for the march before the ACLU, Planned Parenthood, and Amnesty International got on board. More on Teresa Shook here.
• The march itself will be preceded by a rally at the National Mall starting at 10am. America Ferrera, Gloria Steinem, Ashley Judd, and Michael Moore are just a few who will speak, while Janelle Monae will perform.
• Harper's Bazaar points out other celebrities who'll be in attendance, including Scarlett Johansson, Debra Messing, Katy Perry, Lupita Nyong'o, and Zendaya.

• Actress Constance Wu of ABC's Fresh Off the Boat tells the Hollywood Reporter why she'll be there, citing the "patriarchal standards … woven into the fabric of our existence."
• But there won't just be celebrities, of course. The New York Times explores why a group of Wall Street professionals feel a duty to attend.
• The Huffington Post lays out the rights of protesters and offers tips on what to wear and what to bring (and not bring: signs with handles are a no-no).
• While the Amplifier Foundation will be circulating posters, Bust offers a few of its own designs, one of which features Rizzo from Grease. Chicagoist picks out some of its favorite signs; ditto Elle and Bustle. Co.Design offers tips on how to make the "perfect" sign.
• Can't attend in Washington? An estimated 2 million people are expected to attend various "sister marches" around the country and the world, including in Kenya, Japan, Albania, and New Zealand, per Bust. Marches are happening on all 7 continents, reports Grist, with one march being held on a ship that sits off the coast of Antarctica.
