I visit SO at random times (weekdays, weekend, day, night) and often find that I'm sat waiting for new questions to come in. Is there a way I can run some stats to figure out when (day of week, time of day) the more popular questions are typically asked for a given set of tags?

It seems that at all times of all days, there a lots of localized JS questions asked. Most of these are arguably bad questions and don't really catch my interest. I want to know when it's best for me to visit to be involved in the gems that receive a lot of views and interest.

To my feeling, 13:00-17:00 UTC in working days are the busiest. Further I don't think that gems have a specific distribution. –  Chichiray Dec 28 '12 at 13:05
@Chichiray. That seems about right. Weekends here (UK - more or less UTC) are quite and littered with boring "why isn't my JS working?" style questions. Of course, 13:00-17:00, being in work hours, is not great for me :(. I was hoping to be able to get some figures to be able to compile a chart to demonstrate the best times. Then I'd be able to make more efficient use of SO. The wife would be happier too! –  flem Dec 28 '12 at 13:08
You should be able to generate charts based on data.stackexchange.com. Greg Hegwill has done some before: meta.stackoverflow.com/questions/65/stack-overflow-stats-graphs and hewgill.com/~greg/stackoverflow/stack_overflow/stats.html but they are some months old now (it at least confirms my feeling of 13-17 UTC being busiest). –  Chichiray Dec 28 '12 at 13:13

So I've knocked up this query on data explorer (which seems to be up to date now :)). The query returns average answer score for answers with score of greater than 10 for each hour of the week for questions asked in the last 12 months.

Here's a graph I generated from the results: enter image description here

I appreciate that's quite difficult to see but what is quite obvious is that there are five high zones (circled). The first three zones are Monday-Wednesday early hours (UTC) 02:00-12:00. The last two are Thursday-Friday in the middle hours 08:00-18:00. There's an apparent anomaly in the middle. This value is 67.55 for Wednesday 13:00 - 13:59. Just as a guess, there's probably a particular answer with a score of several thousands. I've haven't looked into this.

I can conclude from this that the best time to be SOing is during work hours. My boss will be so pleased!

Just looking again at the spike in the middle and it occurred to me, that must be Jon Skeet! :) –  flem Dec 28 '12 at 16:06
