Why do the times differ between Cancún and Shanghai?

Cancún, Mexico (GMT-5) is 13 hours behind Shanghai, China (GMT+8).

How is this conversion worked out?

Shanghai runs on Asia/Shanghai (GMT+8) and Cancún on America/Cancun (GMT-5), a difference of 13 hours this week. The peak hours themselves are measured in Shanghai local time, and that figure never moves. What moves is the reading on your own clock, twice a year, when either place changes for daylight saving. The two places do not always change on the same date, so for a couple of weeks each spring and autumn the difference is an hour off its usual value; that is why these pages are rebuilt every week rather than computed once.

Does any platform peak on a different day in Cancún?

Facebook, Instagram, X and YouTube peak on a different calendar day in Cancún than in Shanghai, so scheduling by day name alone will miss them. Converted times use the offsets in force this week (GMT-5 and GMT+8). The audience-clock column never changes; the converted column is rebuilt weekly so it stays right across daylight-saving changes. The same times apply across Shanghai's timezone, including Beijing, Shenzhen and Guangzhou.
