Your Complete Guide to March for Our Lives Rallies From N.Y. to L.A.

From coast to coast, throngs of teenagers will be joined by celebrities, teachers, parents and everyday Americans this Saturday to march for their lives.

They’ll be taking part in a nationwide demonstration — called March for Our Lives — organized by the student survivors of the shooting at Marjory Stoneman Douglas High School, where 17 people were shot and killed by a former student on Valentine’s Day. More than 500,000 people — in major cities like New York City, Boston, Chicago, Los Angeles and Portland — are expected to march in solidarity with the Florida shooting survivors to advocate for gun control and school safety.

Following the shooting — now the deadliest high school shooting in the country — the students from Parkland, along with students around the country, have been taking action: Visiting statehouses to demand legislative action, staging walkouts, and organizing marches. More specifically, a group of students from Marjory Stoneman Douglas High School have been organizing March for Our Lives in Washington, D.C., and satellite marches have popped up around the world. (The March for Our Lives website has a search feature to find an event location.)

Here’s everything we know about seven satellite March for Our Lives protests planned across the U.S., including meet-up locations, timing and who is expected to speak:
