Is there a daily pattern in closing questions?

Anecdotally, I get the impression that more questions are closed at night then in the morning (my timezone is UTC -5). Are there times of day where questions of the same quality remain open longer? Is there a time of day where low-quality questions (which sometimes do reveal intriguing ways of thinking about chemistry) have a higher chance of getting an answer? Once the question is closed, the only way the OP will get feedback is through comments, if folks even spend the time to look at closed questions.

• Not a terrible topic to bring up, but could you state some of the implications you think this timing might have/what you want for input from us? There isn't much to answer. – A.K. Feb 24 '19 at 19:03
• Since closing is (mostly) done by the community, questions get closed whenever people are active. Anecdotally, most people who close are in Europe/US, so it makes sense that it happens at night. I don't see a problem, though. If a question should be closed, then there's nothing wrong with closing it, and if they need feedback on the question itself then the comment section is the correct place for it, as the answer section is for answers. If questions are being closed unfairly, then that's another issue, but it doesn't seem to be what you're concerned about. – orthocresol Feb 25 '19 at 11:47
• I agree that there is no problem. It is possible that new users might get a different impression of the site depending on when they use it. Sometimes, they will see that most of the recent questions are closed, and sometimes they are not. – Karsten Theis Feb 25 '19 at 17:33

I ran this script to return the number of questions closed per hour. I'm in Greenwich Mean Time so I assume these results are too.

SELECT
DATEPART(hh, ClosedDate),
COUNT(*) AS ClosedQuestions
FROM PostsWithDeleted
WHERE PostTypeID=1 AND ClosedDate IS NOT NULL
GROUP BY DATEPART(hh, ClosedDate)
ORDER BY DATEPART(hh, ClosedDate)


It seems to correlate pretty well with the number of questions ask per hour.

DATEPART(hh, CreationDate),
