Taylor Swift released 1989 a year ago today, and she recognized the special day with a post on Twitter calling this past year the best of her life.

Understandable: The album, Swift’s fifth, debuted at No. 1 on the Billboard 200 and went on to become the fastest-selling album in over 10 years. It was also the top-selling album from Dec. 29, 2014 to June 28, 2015, according to Nielsen’s mid-year charts released this past July.

The 1989 tour has also made headlines with dozens of guest stars like Lena Dunham, the U.S. Women’s Soccer Team, Justin Timberlake, and Julia Roberts. As of earlier this month it had grossed $152.6 million since May and will continue into December.

Ryan Adams also covered the album in full this summer, and Swift called the project “such an honor.”
