Tsukimi (月見) or Otsukimi (お月見), meaning, "moon-viewing", also known as Jugoya (十五夜),
are Japanese festivals honoring the autumn moon, a variant of the Mid-Autumn Festival.
The celebration of the full moon typically takes place on the 15th day
of the eighth month of the traditional Japanese calendar;
the waxing moon is celebrated on the 13th day of the ninth month.
These days normally fall in September and October of the modern solar calendar.
