Lunar Cycles: I need help


Off-Topic Discussions


I need a website that says it plain english that the new and full moon occur at least three times a month. Convincing my mom that I'm right on this is providing her with a free education in the matter, as her looking at an image of three full moons on a lunar calendar on my monitor isn't enough as "they might not be showing all discrepencacies for rotation".

I think you'll probably have trouble finding such a site, since they only occur once each a month (or one will occur twice on occassion as the lunar month is only 29 days). Then again, this is the internet, so such sites probably do exist.


This calendar site shows me differently.

No, that site shows approximately 1 full (and 1 new) moon each calendar month, with that 1 full moon appearing to last for about 3 days.

Blue Moons are two Full Moons in a month. Based on your OP, if you're looking for 1 Full, then 1 New, and another Full, you're in the right place.

A moon is full for 3 days in a row, but those two are only a "partial full" as it takes until the second day to be truely full (but works on Lycanthropes). Three Fulls, by true definition, are impossible.

Lunar Phases may help as well.

As Callum and tdewitt says there is typically only 1 full and 1 new moon each month. When there is more than 1 full moon in a single month is where the phrase "Once in a Blue Moon" comes from. Because it is very rare it happens.

Now you are right in that most calendars show 3 days long of full moons but technically only one of them is the actually full moon. The other days are just nearly full as in 95%+ full but not 100% full.

About the meaning of the phrase Once in a Blue Moon and how often it occurs.

Twin Agate Dragons, it looks like insulting your mother's intelligence is a bigger priority than assuring your own. You should give her a break, I bet your childhood was a very long one for her.


Okay, so I was wrong. But I thought I was right.

Can you find it in your heart to forgive me?

What you can tell your mom is that the the moon will go through a full cycle approximately once every 28 days.

Actually, that is a common misconception. A blue moon is the 4th full moon in a season. The only way it can happen is if there are two full moon in a month, but that 2nd full moon in a month is not (necessarily) the blue moon. The 2nd full moon in a month name comes from a misquote in a newspaper something like 70-80 years ago and it has been conventional wisdom ever since.

But yes, Full Moons and New Moons happen (on average) once per month. To be exact, there is exactly 29.5 days from full moon to full moon (or new moon to new moon). The day before and day after each full moon (and new moon) there is little variation in the phase and are largely considered to be part of the full moon (or new moon) phase, but it is still a single occurrance of the phase.
