Here's yours:

You do post up until about midnight (though I am inferring your location as in the UK somewhere),

but there's a clear strong band of posts about 2/3rds the way into the evening. You don't post past midnight but start posting fairly early. 

The width of the band is, of course, because the elevation of the sun is much higher in the summer than the winter, so you can get a feel of the seasonality of the posting as well.
