An en dash connects numbers and sometimes words: 2010–14, 11 a.m.–4 p.m., UW–Madison. It also shows a range in numbers and words: 20–25 people, Monday–Friday. Use an en dash with open compound modifiers: pre–School of Pharmacy course. When connecting years with from, also use the word to, not an en dash: from 1980 to 1986, not from 1980–1986. For news releases or Inside UW–Madison, use a hyphen to connect years: 1980-86. Do not put spaces on either side. see also CMS 6.78–6.81
