* Assuming standard Monday through Friday work days and excluding Thanksgiving and Christmas day.
The calculation is pretty straight forward. Subtract the ending reported VIN from the starting VIN for a given month and divide that by the number of work days for that month and round any remainder down.
Disclaimer: The monthly production totals are those reported by GM. It is known in some years, some plants had shorter production runs in their first month and last month and may also have produced more Chevelles overall than reported. However, the above figures are based on what is published and generally accepted numbers.
The figures assume a full month but with beginning and ending months this would, naturally, not be the case.
The figures calculated are NOT to be taken literally but are for general information only.

* Caveats and Disclaimers:
The numbers shown are reported last VINs from each plant per month. The numbers above those in red are instances of matching VIN and Fisher Body plates to show VINs/body dates outside the published numbers. The Fisher Body Number plate build week not match the calendar week; meaning an example body date of 04A may not be the first physical or even calendar week of April. Productions are scheduled well in advance of actual build date and given it takes 3 to 4 days to physically build the car once it is scheduled, you can see where the body date will not always match up with the VIN sequence. Obviously the body plates, and the associated information, are stamped when the cars are scheduled, not as they roll by a particular station. Cars with 04A body dates may run into week 04B of production. GM wouldn't just toss out the existing body number plates with 04A just because the car didn't physically get completed until the following week.
In reality, don't place too much emphasis on the body date as opposed to the last reported VIN for a given month. The anomalies shown are shown for that very reason. It does happen and that should not be a basis for worry that your car may have had the body plate (trim tag) and/or VIN altered.
I would be very concerned of the engine assembly date vs. data in the VIN and body date issue. An engine with an assembly date after the Chevelle was assigned a sequence number would not be possible. The same holds true for any major driveline component. The Chevelle could not be built with, say, an engine with a build date of March in a February dated Chevelle.
If you have trim tags/VINs plates with dates and sequence numbers that don't fall into the range of those shown below, please email me the trim tag and sequence number and I'll post the oddity. Email it to me via my contact page.
