Best time to post, measured on viral posts, one page per network

Every page that ranks for "best time to post" studies ordinary accounts and asks when they get the most engagement. Ours asks a different question: when were the posts that actually went viral published? We hold the timestamp of each one, and the page lets you open them.

• The five best slots with a hit rate: how many posts published in that hour made the network's top 10%, against a 10% baseline.
• A 7-day by 24-hour heatmap, a 24-hour ring, the worst hour, and a section per weekday with its own three best hours.
• "Today" in your own clock, and a time-zone table for the three best slots.
• The three most viral posts published in the best slot, so the claim can be checked.
• The sample month by month, the method, and seven answered questions.
