National School Walkout: Everything to know about the upcoming event to end gun violence

Thousands of students across the country will come together next week to rally against school gun violence -- an event the teenage organizers hope will empower students to continue their momentum in a push for common-sense gun reform.

The event -- called the National School Walkout -- focuses on high schools and will take place on April 20, the anniversary of the massacre at Columbine High School in Colorado, where two students opened fire in 1999, killing 12 of their fellow students and a teacher.

Who is participating?

The event was organized by 16-year-old Lane Murdock, a sophomore at Ridgefield High School in Connecticut, along with three of her classmates.

More than 2,000 events are registered across the country, with at least one in every state and several globally, according to the organizers.

There are currently more than 2000 #NationalSchoolWalkout events.

When will it start?

The walkout begins at 10 a.m. in each local time zone.

When students head outside, they will first take part in 13 seconds of silence to honor the 13 people killed at Columbine High School.

Then the format of the walkout is up to each school. Lane told ABC News she proposes that schools incorporate open mics, guest speakers and voter registration. She said some students plan to write letters to those in communities impacted by school shootings.

This is a problem that needs to be addressed longer than 17 minutes.

But this event differs in one major way from last month's nationwide school walkout, which was held on March 14, one month after the shooting at Florida's Marjory Stoneman Douglas High School that killed 17 students and staff.

The March 14 walkout officially lasted for 17 minutes to mark the 17 lives lost. After the 17 minutes, many students returned to their classrooms.
