The worst day on Instagram? Sunday, same as Facebook. Maybe that’s because people are more likely to be at home or engaging in recreational activites on Sundays, and therefore less likely to be spending time in the apps. 

On Twitter, Wednesday and Friday also come out on top.

But as you can see, Saturday is, overall, Twitter’s worst, not Sunday, which seems like an interesting variance.

Over on LinkedIn, Spout’s data suggests Wednesdays from 8–10 a.m. and noon, Thursdays at 9 a.m. and 1–2 p.m., and Fridays at 9 a.m. are the most engaging times.

LinkedIn’s best days are Wednesday and Thursday, and it’s worst is Sunday, staying with the broader trend – though Mondays, too, look pretty slim on LinkedIn.
