Day 150: Use an en dash to show a range.

The en dash is longer than a hyphen and shorter than an em dash. It is called an en dash because it is approximately the same width as the letter N based on old typesetting standards. The primary use of the en dash is to demonstrate a range of values that includes fixed lower and upper limits. Here are some examples.

“The cost is $12–$14.”

“June–August is my favorite time of year.”

“The years of the Civil War (1861–1865) were difficult for both sides.”

“pages 22–24”

You can usually find the en dash under symbols or on the character map. Most word processors will convert space-hyphen-space to the en dash, though you may need to remove the extra spaces. The en dash has no spaces between it and the words on either side.

Text editors may not convert the hyphen to the en dash. If you cannot produce the en dash, you can simply use space-hyphen-space. In formal documents, however, use the en dash.
