Due Dates

Calculation of the due date of an issued item is a surprisingly complex task. One might think it is simply adding the number of days for issue to the issue date.

But one might be wrong!

Latest Dates

There are three “latest dates” in Athenaeum. By “latest”, we mean that if an item is issued and calculated to be due after one of these dates, then the due date is “wound back” to that latest date.

Athenaeum Latest Date

Athenaeum will never automatically calculate a date past this date. Many libraries set a latest date of a few weeks before the end of year stock take, to allow time to arrange for all items to be returned.

This date is set in Admin->Dates->Latest Dates and Recesses

Don’t set the due date to be “today” as that means everything will be due immediately.

Borrower Type Latest Date

Each borrower type can have their own latest date. For example, a high school might have a borrower type for year 11 students who leave the school earlier in the year than year 3 students. Simply set this date in the detail screen for that borrower type.

Borrower Latest Date

Individual borrowers can also have their own latest date, set on the detail screen. Issues to that borrower will not be automatically calculated past that date.

Adjusting Latest Dates

When you adjust a latest date, Athenaeum looks at any issues that are currently due and that are beyond that due date. If it finds any, you are asked if you want to see the issues for the system/type/borrower or whether you immediately adjust the dates back to the new latest date.

Date Calculation Considerations

Starting with the issue date, the following tests are some of the factors that influence the calculated number of days:

• is the issuer in override mode, having specified the number of days to issue?
• the default number of days that the borrower is normally allowed
• is the issuer in “go” mode, then many tests are ignored
• the fixed number of days if the item has that specified
• the maximum number of days if the item has that specified
• if the due date is a Saturday, Athenaeum checks that Saturdays are valid due days
• if the due date is a Sunday, Athenaeum checks that Sundays are valid due days
• if the due date is a public holiday, Athenaeum bumps the due date 1 day (and checks again)
• if the due date is during a recess, Athenaeum bumps the due date 1 day and repeats the check
• if the due date is after the borrower’s “latest date”, it is wound back
• if the due date is after the borrower type’s “latest date”, it is wound back
• if the due date is after the Athenaeum “latest date”, it is wound back

Manually adjusting a due date

Navigate to the issue module and find the issue you wish to adjust (e.g. main menu -> circulation -> find).

If you are in list view, click on the issue to see the detail view.

Simply enter a new due date in the due date field.

Manually adjusting a found set of due dates

Find all of the issues whose due dates you wish to adjust and view them in list view.

Ensure that the found count matches the number of issues you wish to reset.

Press the Command button and then “Reset these due dates”

Confirm that you wish to reset the due dates:
