Deletion of Sukuma calendar

Comment: Whether the Sukuma have a calendar or not, this article presents a |verifiability problem as well as attributing beliefs about it to no one and not completely making sense. It provides no source for a calendar emerging "about 5,776" sic years ago, and I find no matches through Google or Google Scholar supporting this. The second half of the lead sentence seems to be a non sequitur. It says the Sukuma are "believed" to have advanced their astronomical skills without saying who believes this, or even why noticing the shifting nighttime sky marks an ''advancement'' of astronomical skills rather than being pretty basic. Unless they're using the Gregorian calendar, their solar festivals wouldn't be on the same Gregorian date every year; there's no mention of the months of this calendar, even how many of them there are in a given year (12? 13?), which means this article covers some details without establishing a foundation with the necessary basics. Without sources for this information, it would be impossible for anyone to fill this in or verify what's already there
