Ted Mosby and Tracy McConnell marry in 2020.
Their relationship begins after Ted meets Tracy at the Farhampton train station following Barney and Robin’s wedding in 2013. Tracy is revealed as the long-awaited “Mother,” and the couple later build a family together, raising Penny and Luke.
The wedding year is easy to confuse with other major dates in the show. Ted meets Tracy in 2013, they become engaged in 2015, and their children are born before the wedding. The series finale then jumps forward to 2030, when Ted tells Penny and Luke the story of how he met their mother.
Another important detail is that Tracy dies in 2024, four years after the wedding. That later tragedy explains why Tracy is absent when Ted narrates the story in 2030, although the wedding itself still takes place in 2020.
