CHEYENNE, Wyo. — A Wyoming superintendent has postponed his district’s first day of school because he says he “grossly underestimated” how significant the solar eclipse is going to be.

Laramie County School District 2’s first day of classes was scheduled for the same day as the eclipse, August 21, but was changed to August 22.

Superintendent Jon Abrams says he didn’t realize the eclipse was going to be a “once-in-a-lifetime thing” and wants students, parents and teachers to be able to witness it.

Abrams says the district is in the area that will have a 98 percent eclipse.

Students will attend school on Friday to make up the hours missed on Monday.

The district still plans to offer an eclipse field trip to all of the district’s secondary students.
