Not to `normal' humans. For most of us a `standard clock' is [12AM, 1AM, ... 11AM, 12PM, 1PM, ..., 11PM] and at TV guide (for reasons that are probably obvious) we used [6,...,29] for a `standard day'. again for `communications' reasons. Note also that astrophysical days start at noon, not midnight, and days in the Jewish calendar, I think, start at Sunset. So even here there's a veritable panoply of 0- and other- origin indexing. My conclusion is that Sassenrath is correct: 0-origin indexing is enormously intellectually more satisfying (J and K, current day derivatives of APL, for example, use it) but for `normal' communication 1- is probably the better choice. And since it;s his playing field, bat and ball, I'm content with the choice. For me, more alternatives wouldn't be better...
