Monday's solar eclipse is a very big deal: A total solar eclipse visible from the West Coast to the East Coast hasn't occurred since 1918. While D.C. will only get a partial solar eclipse, it's still worth seeing.

The eclipse will begin at 1:17 p.m. and last until 4:01 p.m., according to NASA. The peak will come at 2:42 p.m., when 81 percent of the sun will be covered. If you can sneak out of the office for a few minutes, museums and science facilities in the area will be holding eclipse viewing parties with telescopes and other activities, while bars and restaurants are getting in on the act with themed cocktails and events.

Remember: You shouldn't look at the eclipse without protective glasses. Though they may run out, the locations below are giving away free glasses, except where noted. If you need a pair, try your local library or Warby Parker, which has free American Paper Optics safety glasses at its stores. The American Astronomical Society also has a list of reputable vendors.
