Many Americans are demanding more gun regulation in the wake of the slaughter of 17 students at Marjory Stoneman Douglas High School in Parkland, Fla., last week at the hands of a former student armed with a semi-automatic rifle. 

Led by the example of passionate Stoneman Douglas students, gun-control advocates across the U.S. are planning massive demonstrations in the coming weeks and months to shine a spotlight on the issue. 

Here's a rundown of some of the scheduled protests: 

Feb. 21: Parkland students to rally at Florida Capitol

Busloads of students from Stoneman Douglas High School are expected to go to Tallahassee, Fla., Wednesday, to march on the state Capitol to demand more stringent gun laws. 

The students are expected to begin their more than 400-mile trip Tuesday after the funeral of their 16-year-old classmate Carmen Schentrup. 

The superintendent for Leon County schools, which includes Tallahassee, said students will be given an excused absence to attend the rally.

March 14: #Enough National School Walkout 

The organizers of last year's massive Women's March on Washington are calling on "students, teachers, school administrators, parents and allies" to participate in a nationwide, 17-minute school walkout at 10 a.m. on the one-month anniversary of the Marjory Stoneman Douglas shooting. 

Organizers said the event is meant to "protest Congress' inaction to do more than tweet thoughts and prayers in response to the gun violence plaguing our schools and neighborhoods."

March 24: March For Our Lives 

"In the tragic wake of the seventeen lives brutally cut short in Florida, politicians are telling us that now is not the time to talk about guns. March For Our Lives believes the time is now," reads the mission statement from March For Our Lives, a nationwide student organization. 

On March 24,  protesters will march in Washington, D.C., "to demand that their lives and safety become a priority. The collective voices of the March For Our Lives movement will be heard."
