Comment 4 for bug 1818912

Since my initial report, I noticed that the undesired behavior doesn't just happen on single day closures, but also multiple day ones depending on surrounding closed dates.

Here is what we recommend to our libraries:

If adding a date surrounded by existing closed dates, you should add a closing for the entire period to ensure due dates are updated correctly.
For example, If you’re always closed Sunday, are closed Monday for the holiday, and the town approved closing Saturday, don’t enter just Saturday as an emergency closing, instead enter a multi-day closing of Saturday through Monday!
