A thread of all of the evidence that I have that...
1989 (Taylor's Version) will be announced May 13
Wildest Dreams (Taylor's Version) will be out May 14
The first (From The Vault) track will drop June 4
1989 (Taylor's Version) will be out June 25

** disclaimer **

some of the evidence in this thread comes from hints from theallknower

May 13th is a Thursday and May 14th is a Friday that adds to 13 (1+4+5+2+1=13). I think there will be an announcement on Thursday with the first song dropping on Friday, similar to how Love Story and Fearless TV was announced. So what evidence do I have for these dates?

Colbert Interview:
1. Taylor references Colbert's Wikipage. One of the first things you see is his birthday, MAY 13th!
2. She says he was 44 years, 179 days old. 179-44=135 or 5/13.
3. His office was on 513 street. Once again, May 13th.
4. The SSN adds to 14 (3+3+0+3+5=14)

We all know Taylor plans ahead. Initially, Spirit Untamed (the movie with Wildest Dreams in the trailer) was set to premiere May 14th. Although it is now set for June 4th, I think Taylor would stick with the original release date for Wildest Dreams

Next, numerical 'coincidences' include...
1. May 14th is 13 weeks after Love Story (Taylor's Version) dropped.
2. Taylor has been using 3 emojis. Well, 3 weeks after her last tweet on April 19th would be the Monday before May 13th and 14th.

Lastly, some hints from theallknower point to this date too:
1. On May 5th, they responded to a tweet saying "something". That is 9 letters and 9 days after is May 14th.
2. They said we are toward the latter half of the musical drought, which points towards mid-May to early June

Next, the release of a vault song seems likely on Friday, June 4th (6+4+2+1=13):
1. This is the new release date for Spirit Untamed, which will feature Wildest Dreams TV

2. theallknower posted a tweet on May 3rd with 2 "big words": latter and simultaneously, and urged ppl to google them.

latter's definition has 1989 in it
simultaneously's definition has the number 31 in it

31 days after their tweet is June 4th.

Finally, why #1989TaylorsVersion will drop June 25th:
1. The instagram color theory states that each of these photos correspond to an album (1989=blue, sorry). The number of words in the captions signal the month which the album will be released...

There were 4 words in the caption for yellow (Fearless), which dropped in the 4th month, April.

There are 6 words in the caption for blue (1989) so it will drop in June.

The Colbert interview also gave references to June 25th...
1. 44 years, 179 days adds to 25 (4+4+1+7+9=25)
2. They emphasize Stephen with a PH. P is the 16th letter of the alphabet and H is the 8th. 16+8=24, or the day before the album drops.

Next, some of the out-of-place letters in the Hey Stephen lyric video can spell out 'nineteen eighty nine'. There are 77 raised letters, and June 25th is 77 days after April 9th.

Lastly, the location that was in theallknower's bio (23415~6) could hint to this date too:
If you unscramble the numbers, you get 5/13 (announcement day) and 6/24 (the day before it drops).

THE END! What are your thoughts?
