OK, so this is where things get a little complicated. Some fans seem to think Swift's post is actually the release date for her first single on the new album. If you look close enough, there is a number three highlighted in the trees on the right and a number five highlighted in the middle, which could mean we'll be getting new music on March 5.
Alternatively, fans think the palm trees could signal when Swift will start doing promotion for her upcoming album. In her 2019 calendar, specific dates are marked with a stamp, including April 13. While we know 13 happens to be Swift's lucky number, April 14 is actually Palm Sunday. And if you look at the amount of palm trees in the photo, there are four palm trees on the left, one in the middle, and two on the left. Put that all together and you get 4/12. Maybe an announcement on April 12, a single release on April 13, and a music video on April 14?
