So? Any notation system is completely valid to quantify things, and yes that includes calendar years.
That's literally the entire point I'm trying to make to y'all!
Also @Page Scrawler, e is not 2.71828 since that's merely an approximation.
Also also, 2.71828 years is approximately 2 years, 8 months, 18 days, 14 hours.
No, I said it wasn't a unit of measurement. Units of measurement are things like feet, seconds, and pounds. Notations like decimal or binary are in and of themselves not units of measurement.
It's like I'm talking to a brick wall.
