In the API, User object, what are all these reputation properties?

Question

I am going through the JSON that is resulting from calling the Stack Exchange User API.

I see a bunch of reputation fields.

private Number reputation;
private Number reputation_change_day;
private Number reputation_change_month;
private Number reputation_change_quarter;
private Number reputation_change_week;
private Number reputation_change_year;

What are all these for? Obviously, I know what the reputation is, but the others have me a bit fooled.

Answer 1

This is just the reputation that the user has earned for the given period (day/week/month/quarter/year).

For example, for you, for Stack Overflow, the API currently returns:

"reputation_change_day": 0,
"reputation_change_week": 0,
"reputation_change_month": 32,
"reputation_change_quarter": 63,
"reputation_change_year": 111,

This should jibe with what you currently see on your "multi-super-whatever-you-call-them drop down".

It matches what we see on the Users page, reputation tab:

And what we see in the Reputation Leagues :
