I imagine that diagonals run in the top-left-to-bottom-right sense, and anti-diagonals in the top-right-to-bottom-left sense (or vice-versa).
How many diagonals does a chessboard have?

Yeah, I saw the term on this chess programming wiki, and that's pretty much how they described it.

But I've never heard the term being used by chess players, or in chess books.

When we think of of ranks and files, it is accepted at 8 apiece. But what about diagonals? Looking at the board, I am inclined to say 26. But other places I saw as many as 30 (they include the 4 corner squares as diagonals ?? how can a diagonal be one square?) And as it related to chess programming, they talk of 15 diagonals and 15 anti-diagonals. I didn't even know the term "anti-diagonal" was even used : /
In "https://www.chessprogramming.org/", they consider only "a1" or only "h8" as a diagonal.
But considerate one square like a diagonal it's not usefull (in human chess).
