On: Looking back at 9 years of Hacker News

On the graph of total posts over the days of the week, do you know what time and timezone are the peaks? it seems very regular, like if only one/a few timezones where concerned. Do we have such a little posting power in Europe ... ?

As someone from Europe: This looks exactly like the 15h UTC peak in most US websites and chats when all the Americans come on.

The peak starts at 12h UTC, is largest at 18h UTC, and goes down at midnight UTC – exactly what I’m used from US people in the chats I am,

and exactly 4am PST, 10am PST, and 4pm PST.

or 8am Eastern Time, 4pm Eastern Time, and 10pm Eastern Time.

Which is Silicon Valley Morning/Workday, East Coast Workday, and European Evening.

Same as reddit.

I charted the peak times here:

(Python notebook - renders well on desktop, but GitHub might not show a nice rendering if you try it on mobile)

I should've mentioned that all the times are in UTC. I'll work on normalizing them to PST - it's pretty confusing right now. Thanks for letting me know!

Please leave them in UTC if possible. I do realise from your data that the bulk of readership of HN is US based.
