Messidor was the tenth month in the French Republican Calendar. The month was named after the Latin word messis, which means harvest.

In the ancient Roman calendar, Quintilis or Quinctilis was the month following Junius (June) and preceding Sextilis (August). Quintilis is Latin for "fifth": it was the fifth month in the earliest calendar attributed to Romulus, which began with Martius and had 10 months. After the calendar reform that produced a 12-month year, Quintilis became the seventh month, but retained its name. In 45 BC, Julius Caesar instituted a new calendar that corrected astronomical discrepancies in the old. After his death in 44 BC, the month of Quintilis, his birth month, was renamed Julius in his honor, hence July.

Thermidor was the eleventh month in the French Republican Calendar. The month was named after the French word thermal, derived from the Greek word "thermos" (heat).
