Help decoding manufacturing dates from Polaroid batch numbers

Hello,

I was trying to date some old Polaroid photos and noticed the batch numbers on the back, I Googled and found a few guides at various sites and blogs, but I still can't fully understand it as there appears to be many different batch number formats for each type of film.

First of all, I have no idea what type of film the photos are on. They look like standard Polaroid photos to me. These are three examples of the batch numbers on the back, could someone please help me to decode the films' manufacturing dates of these batch numbers?

Thanks for replying, but as stated in my OP I had already done that and found several sites and blogs that explained the batch codes, but still was having trouble with those three ones I listed. After contacting polaroidoriginals.com I did receive help with the first two, but not the last one which unlike the rest only contains 9 digits and not 11 digits. I have looked in all guides and documents I can find, and the only codes with 9 digits I find any information about also contains letters, which this code doesn't (only numbers).

So question still remains, can someone decode this one?

Found that wrestling with my own question. My photo has the following code:

2308224131 Polaroid 3.

According to the above site, an 11 digit code is pre-1980 and starts with the prototype number. Post-1980 film starts with the month number and has 12 digits and the prototype code follows the Polaroid logo. I can't find prototype a prototype code 23. This site suggests that Prototype 3 code indicates Spectra / 600 Hybrid-4-RA film which is a wider format. My photo is a standard square format. However, an individual in the picture is wearing Walkman-type headphones placing it post 1982.
