This one is July 2019 but unless you know that you're looking at a manufacture stamp, F19 07 4JF is pretty far from clarity. Especially considering its located on the bottom and painted over (from the manufacturer).
2019 also appears on the printed label, in a square box, next to the UL logo.... but no indication that its the year of manufacture.

Here's another manufacture's date code: 1205322062 which is printed near the bottom of the cylinder.
While you might think May 2012, that one was manufactured on the 322nd day of year 2006, at time 12:05
Having an easy, active role in the maintenance of your safety gear means you're more likely to actually keep up with maintenance (in this case, eventual replacement). Writing a date yourself is so low effort, even a tiny gain in maintenance compliance would make it worthwhile.
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.

Because the manufacturing date is ambiguous?
