We deal with dates quite a bit when invoicing customers for our web hosting business. We just encountered an interesting language snafu and I thought it would be interesting to post for discussion.
A good example is the following:
January 1, 2008 to February 1, 2008.
January 1, 2008 through January 31, 2008.
Which is better? Each is technically one month of time. But the way you phrase it is important.
