Between May 15 and July 17, 1941, DiMaggio held the longest consecutive game hitting streak (56 games).

If you're going to use "Between" then you need to use a word ("and") instead of a hyphen to indicate the beginning and ending of the time period. And don't forget the comma AFTER the year, too.
Actually, I wanted to use the sentence below:

During May 15-July 17, 1941, DiMaggio held the longest consecutive game hitting streak (56 games). Does that make sense?

**It makes more sense because it was during that year, not between it.

Thanks!!
