That means fans are now wondering what the other stamps symbolise. It could be an album release date, an awards show appearance, or even another countdown.

One fan even went so far as to figure out when an album would drop based on the release dates of Taylor’s previous albums, and discovered if a lead single was released on April 26, an album could be expected in mid-July — and there's a stamp on July 13.

Another fan has speculated that the seemingly random timing of Taylor’s Instagram posts since the countdown actually have some significance, and Taylor Nation’s tweets corresponding to each post are hinting at further important dates this era.
