| Item loan period, overdue charge | Item loaned at | Item due date | Item returned at | Service Point Hours / Charged for Closed? | How does the overdue calculation work? |
|---|---|---|---|---|---|
| Example scenario that works as expected | |||||
| loaned for three hours, overdue $3/day | 2:00 PM 9/1/2021 | 5:00 PM 9/1/2021 | 6:00 PM 9/2/2021 | Service point open 24/7 / Charge during closed hours / No grace period | The item was overdue by one day and one hour = 28 25 hours = 1500 minutes. The fee/fine is $3/day, which is $3/1440 minutes. FOLIO calculates the number of intervals involved - 1500/1440 = ~1.07 intervals. It then rounds it up to the next largest integer - 2. So it's charging for 2 intervals. So the overdue fine is then the fine per interval (3.00) times the number of intervals (2) = $6.00. |
| Example scenario that doesn't work as expected: | |||||
| An item is loaned for seven days, with an overdue fine of $3 day | 2:00 PM 9/1/2021 | 9/7/2021 11:59:59 PM | Item returned at 9/10/2021 2 PM | Service point closes at midnight and opens at 8 AM the next day, every day - charge for closed hours is set to 'No' | The item was overdue by 2 days and 14 hours (strictly looking at the calendar.) That's 62 hours - 3720 minutes. But, the library was closed from midnight to 8 AM for three periods - the morning of the 8th, 9th, and 10th. So that means that there are 24 hours that shouldn't be counted. So then it becomes 62 hours - 24 hours = 38 hours. So if you take that to the interval stage - 38 hours / 24 hours - you get ~1.58, which FOLIO would round up to 2 intervals. So, it would charge $6. Note, though, that it was returned on the third day - so libraries would normally expect a fine of $9, instead of $6. So this scenario does not function as expected. |
