En dashes are the mid-sized dashes (longer than a hyphen, shorter than an em dash) and we use them to either show the span of time, dates or scores, or to show connection or conflict between two words that would not ordinarily be joined. If we have set up the sentence using ‘from’ or ‘between’ it isn’t acceptable to use an en dash between the dates, and instead we would use ‘and’ or ‘to’. Remember, en dashes are for dates, time, scores, or connected or conflicted words only, not as punctuation to emphasize or as punctuation to create a compound word.
