The line changes
2016 onward each year has carried a short theme. 2023 used Meetings Matter. Chapter materials for 2024 used The Event Professional’s Journey. Older years used other lines; this desk does not keep a complete poster archive.
A theme is a press handle. It does not rewrite the history. Edmonton still sits at the start of the paragraph whether the hashtag is new or not.
If you are designing a slide for a chapter breakfast, copy the current year from the chapter, not from a page written after a previous spring.
