Dash
The en dash (–) is the shorter of the two. It is longer than a hyphen but shorter than an em dash. In normal text it is about the width of the letter "n". An en dash is used to connect two numbers that make up a range (for example pages 3–6). It is also used to show a range of dates (2010–2011) or of time (11:30 a.m.–1:30 p.m.).
