Reuters' March 26 article 'Trump says he will pause attacks on Iran's energy plants | Reuters' establishes the prior deadline as Monday, April 6, 2026 at 8 p.m. ET. BBC's 'Trump issues expletive-laden threat to Iran over Hormuz Strait blockage' says Trump later posted 'Tuesday, 8:00 P.M. Eastern Time!' and explicitly describes it as an apparent extension from the Monday April 6 deadline. Reuters' April 6 article 'Trump says Tuesday deadline to make a deal with Iran is final | Reuters' further confirms that by April 6 the operative deadline was Tuesday night. The BlockBeats item at https://m.theblockbeats.info/flash/339727 specifically attributes the '24-hour extension' interpretation to Axios and Bloomberg, but I could not directly fetch Axios or Bloomberg in this run, so that attribution is only indirectly supported. Overall, the core claim that Trump's post pointed to Tuesday 8 p.m. ET and was widely interpreted as shifting the deadline from Monday to Tuesday is well supported; the precise mention of Axios and Bloomberg is less directly verified.
