‘Black Moon’ Today, July 31, 2019, & How It Differs From A ‘Blue Moon’.

by Anura Guruge




The Key Difference:

Black Moon has to be a NEW Moon.

Blue Moon has to a FULL Moon.

Other than that they both refer to an ‘EXTRA’ moon in a given ‘month’.


Blue Moon‘ can mean one of two things:

1. Second full moon within the same calendar month.

2. Third full moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.


Black Moon‘, DITTO, but when it applies to a NEW MOON.

So, it means:

1. Second NEW moon within the same calendar month — as is the case this month, i.e., July 2019.

2. Third NEW moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.


Both are rare events.

Furthermore, today’s Black Moon is a Supermoon — i.e., it is closer to Earth than normal.

Happy Spring Equinox 2019.

[It is also called the Vernal Equinox
— that being the Latin for ‘Spring’.]

I also share with you “Spring“.

Please enjoy.


Sunrise/Sunset for New Hampshire as of the
2019 Spring Equinox.

Notice that it is NOT EXACTLY 12 hours of sunlight on the Equinox.
That is mainly because we are so good at measuring time.
It has to do with the so called precession of the Earth’s axis.
Our rotation WOBBLES like a spinning top.

Sunrise & Sunset Times for Concord, New Hampshire around the September Equinox.
(From Time-and-Date).

Note that daylight is NOT exactly 12 hours!
If anything we get closer to 12 hours 3 days later.
There is a reason for that. It is our latitude above the equator.
If we were closer to the equator it would have been closer to 12 hours.
See this explanation in Time-and-Date.
