Caveats

  • Extraordinary sessions (2000, 2006, 2015, 2020, 2022) are kept as records but excluded from the session-length metric, which covers Regular sessions only.
  • The page prints one convened and one adjourned date per session; 2021's 311-day span (January 11 to November 17) reflects a recess and reconvening with no separate dates recorded.
  • A same-day extraordinary session counts as 1 day; the page's time of day is not kept.
