The presidential inauguration takes place during the month of January. More specifically, the inauguration takes place on January 20. If that date happens to be a Sunday, then the ceremony is held the following day.
Since 1937, all presidential inaugurations have taken place in January following the preceding November election. Before that time, the presidential inauguration was held on March 4th. Every president who is elected for a first or second four-year term must take the presidential oath to officially take office. Except for President Franklin Roosevelt's inauguration in 1945, all presidential inaugurations since 1801 have been carried out at the capitol in Washington, D.C., according to National Geographic.
