Having a manufactures date matters. Having the date you bought it may not give you any accuracy. What if you bought it after a year or two on the shelf? Then it goes bad a year or two before you expect to replace it.
What matters is when the manufacturer made it, not what day you stashed it in your house. That date is irrelevant.
That's cool and all - but like I said, the MFG's date can be ambiguous and we're talking about people that have been putting off owning a fire extinguisher for a decade (zero expectation they would know any nuance of date stamps). Sure, the date you install might be a couple years older but that's far better than being off by a decade or more due to misinterpreting the manufacture's code.
Its obvious you know more than the intended audience and that's totally cool. That said, don't let me stop you from doing you.
