What's the best time of day, or weekday, to ask questions on Stack Overflow? I'd like to know if there might be a way to maximize the exposure or the amount/quality of responses.

At the very least, it would be good to know how to avoid times that might be particularly bad to post.


See the blog for activity over time against GMT (back in January 2009):

    @Marc - now that this is 2 years old, can we possibly get some new data? I can't imagine that the numbers have been consistent as the site has grown.

  • Looks like things ramp up around 9am EST (if I'm reading that right) - hardly surprising Dec 1 '11 at 20:09

    It's now been 7 years since this was posted. Can this be updated with current statistics?

It may be the case that the time you post does not significantly affect the total number of views it gets. Think about the front page exposure, for example: on a particularly busy moment your question spends less time on the front page than it would at a quieter time, so I'm not sure posting at a active moment helps that much.

Now, to maximise the amount of answers early on (which leads to more exposure on front page, and, in many cases, to very high-quality answers eventually, as people compete honing their answers), follow these guidelines: ;-)

  • the topic shouldn't be anything obscure (preferably about C# or Java)
  • the question should be pretty easy (e.g. "Why isn't there a get(index) method in a Set")
  • the question might be ever so slightly provocative or controversial

(I'm not too serious about that, but it is a fact that more difficult questions, or ones concerning a little less-trodden topics, are often left without that many views, or any good answers.)

    Add two language tags. Create a flame war and get lots of answers! Jun 30 '09 at 23:53

    and maybe get your question closed...... Jul 26 '09 at 18:08

Data.SE queries show the best time to ask questions according to different definitions of "the best":

    wait, what is the horizontal axis? Whole days since 0:00 GMT? Dec 26 '13 at 19:27
  • @JanDvorak That's right. 1 = Sun 12am GMT. The graph feature at Data.SE doesn't work with dates, so there are numbers so far. Dec 27 '13 at 2:14

    Wait, the question is about time though!
