Timeline of the 2024 United States presidential election

This is a timeline of major events leading up to, during, and after the 2024 United States presidential election. This will be the first presidential election to be run with population data from the 2020 census. In addition to the dates mandated by the relevant federal laws such as those in the U.S. Constitution and the Electoral Count Act, several milestones have consistently been observed since the adoption of the conclusions of the 1971 McGovern–Fraser Commission.

New York regarding the 2020 United States census, effectively allowing Trump's July 2020 presidential memorandum to stand, which ordered the Department of Commerce exclude the estimated counts of illegal immigrants. The per curiam decision vacated the U.S. District Court's previous ruling on the basis that the case was premature due to lack of standing and ripeness. Justice Stephen Breyer files a dissent, which was joined by Justices Sonia Sotomayor and Elena Kagan, arguing that the Court should have considered the case.
