Measured on viral posts, not opined
Best time to post, network by network
One slot per network: the hour with the highest average engagement among the viral posts of the last year. Open each for the full map, every weekday, the hit rate and the posts that prove it.
Every other page on this question studies ordinary accounts and asks when they get the most engagement. This one asks a different question: when were the posts that actually went viral published? We track them for a living, we hold the timestamp of each one, and you can open them below.
