 "note": "Per-weekday recomputation for the by-day companion page. Two data sets: the 572-post September 2026 creator sample (58 creators, six niches, last 10 posts each) and the 63 unique most-liked videos from nine everyday TikTok searches. Each post's createTime (unix seconds) is UTC; TikTok does not expose the creator's time zone, so all weekdays and hour blocks are UTC. medianPlays is the median playCount in the group. busiestBlocksUtc lists the three most-used 3-hour UTC posting blocks for that weekday, ties broken by earlier block.",
