There was a report that Iran deliberately delayed sealing an agreement until midnight on the 14th (local time), the 80th birthday of U.S. President Donald Trump, to avoid concluding a cease-fire deal on that date.
The New York Times (NYT), citing two Iranian officials, reported that Iran did not want a major cease-fire deal to coincide with Trump's birthday and therefore waited without finalizing the agreement until it became midnight local time.
However, the NYT said the United States and Iran are 7 hours and 30 minutes apart, allowing both sides to claim the final agreement time as they wish.
Trump announced on Truth Social, a social media platform, at about 5:30 p.m. Eastern time that a cease-fire deal with Iran had been reached; at that moment in Iran it was already about 1 a.m. on the 15th.
Inside Iran, hard-liners, including the Islamic Revolutionary Guard Corps, continue to push back against the cease-fire deal with the United States. On the 13th, ahead of the deal's conclusion with the United States, hard-liners in Iran chanted "Death to the disgraceful traitor Araghchi" outside the Foreign Ministry building in the northeastern city of Mashhad, denouncing Foreign Minister Abbas Araghchi, who led the negotiations.
