View Full Version : Blue Moon?

18-01-2008, 03:53
The astrological village idiot (that's me!) has returned with a silly question:

Have I found a blue moon for this year?

As I busily entered new moons, full moons, and the sun entering signs from my Llewellyn's Astrological Calendar into my Outlook calendar, I noticed that there are two full moons in Scorpio (occuring with the sun in Taurus) this year.

Does that mean that the full moon on Monday, May 19, at 10:11 p.m. Eastern time is a blue moon?

Does this have any meaning (except maybe that I'm getting a feel for how the solar system is turning)?

Enquiring minds want to know!

There are a couple of different definitions for a 'blue moon'.

The most common one these days is that if a month has two full moons, the second one is a blue moon.

So (according to my diary) there is no blue moon this year.

The older definition is that a blue moon is the third full moon in a quarter that has 4 instead of the usual three.
I'm not sure how quarter is defined in this context.

I looked it up.

Quarters begin on the spring equinox.
Presumably they would also begin on the other equinox and the solstices.

The wiki has a whole page on it all.

But I don't know why that page says there will be a blue moon on the 30th august this year, as that will be a dark moon....
