Good question Benjy. Callaway's answer is "That's the way we've always done it........" (Yeah, I know). Another point would be vendors performing calibrations generally set the due date as the complete date plus one year.
Not to "justify the practice", but our program allows a grace period, however it requires a conscious decision each time you invoke the grace period. The action has to be logged with the name of who provided the authorization. Most folks that use the end of the month rubric started doing so in order to reduce time and headaches. The idea being that you would pull everything once a month. I'm not convinced this saves all that much, however would welcome feedback from the folks actually doing it. Questions or comments, email or call Dewey at Callaway.

You could make the case for using the periodicity allowance in your TS / TRM for calibration / functional surveillance grace period, say +25% of calibration periodicity, thus semi annual / annual cals due at the end of month would be well within grace period. For those that use exact due date, what technical reference is used for basis?

The other plants in the FENOC fleet use the exact cal date plus frequency as a due date. What does your organization use? A. Due date at the end of the month? B. Exact due date (cal date + frequency)?
