Trying to Find Build Date

[BlueChev72]

Sorry if this has already been answered in a previous thread, but I searched for awhile and couldn’t find anything. I’ve found the model and vin number decoders, which tell the model year of my truck, but I’m curious if there’s a way to find out what day, or at least month, my truck was built in based on the serial number. I guess it’d be serial number ranges that I’m looking for. If it helps, my vin is ccs232a177377 and the model number is cs20903.
