We know with absolute certainty that he died soon after Easter. Literally tens of thousands of people saw with their own eyes that he was alive yesterday (and billions saw it on TV). Exactly when he died between the end of his public appearance and the announcement is hard to know, but also ultimately irrelevant. This would be the biggest topic of discussion in Europe, Africa, and the Americas at the very least regardless of when it happened. And, if there were some goal to increase news coverage in Asia, where there are relatively fewer Christians as a percentage of the population, the announcement (9:45 in Italy) was somewhat late in the middle of the day, at least for China (about 14:45 in China, when everyone is at work and not watching news, either on TV or social media).
So you are being entirely silly.
