Suffice it to observe that the events of 2020 will only happen once on a blue moon, but at the end of October another strange event is going to happen: a real blue moon, Halloween. Two full moons in October this year. October one or two (depending on what time zone you are in) gives us the closest full moon to the autumn equinox, the Harvest Moon, when day and night are of equal length. This usually happens in September but not until October this year. In some parts of the United States, farmers, also known as the Full Corn Moon or Barley Moon, have traditionally made the most of light to collect their crops until the night before the onset of winter. This year the Harvest Moon was again the Hunter’s Moon, named after rural traditions, this time of summer hunting fat animals in the moonlight, and it was bright.

The second lunar month is called the Blue Moon, and there are seven in every 19 years. The name is a matter of placeholder, given to keep other moons in their proper place throughout the year. This is because the Moon completes 12 full cycles of its phase in 354 days, which is the shortest of a full solar calendar year. This year is particularly unusual because it is the first full moon to occur in all time zones since 1944, with one full moon anywhere in the world on Halloween every 19 years, the next being in 2039, followed by 2058 and 2077. Instead, some traditions count the third as full. The moon Blue Moon with four full moons during the astronomical season. In any case, the extra moon is a way of matching the solar and lunar calendars, like the extra month of Adar II in the Jewish calendar, which occurs seven times in a 19-year cycle. In Jerusalem, Israel, the harvest moon occurred within 5 minutes of midnight on October 2, and the blue moon occurred at 4:49 pm on October 31.
