According to the CBS report, many places worldwide will accompany a rare blue moon on Halloween’s eve in 2020. 2020 is the first time since 1944 that Halloween’s full moon will be seen in all time zones in the United States. Unfortunately for werewolves, this won’t happen again until 2039.
The Halloween night sky will be lit by a blue moon, which is the second full moon in a month.” This relatively rare event occurs once every two and a half years on average.” NASA said.
The “once in a blue moon” event does not mean that the moon will turn blue on Halloween. Although the night sky’s dark blue will affect the color, Earth’s satellites might not show any sign of blue color.
The reason for the “blue moon” is that the calendar year and the lunar cycle are not fully synchronized. Since the period of revolution of the lunar calendar is 29.53 days, the lunar calendar will experience a full moon every 29 or 30 days. However, the national calendar has 30 or 31 days per month. So if the full moon is on the first or second day of the first month, the second full moon appears at the end of the month and only once every 2 to 3 years.
The first full moon in October, also known as the harvest month, appears on the first day of each month. The second full moon, or blue moon, will be visible on October 31st. This is the first time since March 2018 that a blue moon has appeared in the United States.
The first full moon in October will appear on October 1st. The second full moon will be clearly seen on October 31st at 10:49 a.m. Eastern Time. According to reports, the last full moon on Halloween in the US occurred in 2001, but only in the Central and Pacific time zones.
