How old am I?

Good day America’s finest. Is there any chart or page which tells how to date all, or at least the most common of, heating and cooling systems? Or do I have to call manufacturers for anything that doesn’t have an obvious date on the tag. I know there are certain systems where one must decipher the date from serial number.
thanks for input

tom…I accessed this site on inspection the day after you told me about it and that’s how fast that info became useful. pulled it up on the job on my handy dandy new smart phone (us old farts are constantly amazed by the new fangled technology) and found the mfg date of an unusual (for me in this area) furnace. rockin!!! you the man!!
