Talk:Days between dates: Difference between revisions

: : The calendar itself isn't really inherently proleptic; I mean, it's usable before its inception date, but that's true of most calendars (though admittedly not all). History is full of proleptic Julian dates, too, like Julius Caesar's birthday. If the task wants you to assume the Gregorian calendar for all date ranges, it should just say so. That would be my vote, anyway: to use the modern astronomical convention of assuming the Gregorian calendar extends indefinitely in both directions in time, and also labeling years before 1 CE with 0 and negative numbers instead of switching to BCE (so 1 BCE = year 0, 2 BCE = year -1, etc) --[[User:Markjreed|Markjreed]] ([[User talk:Markjreed|talk]]) 19:59, 9 July 2020 (UTC)
