Some almanacs like to give each month a special full moon name. Other almanacs like to reference full moons relative to seasonal markers, as defined by equinoxes and solstices. Is one way better than the other? No. Both have their roots in folklore. Of course, both the monthly names and the seasonal names necessarily favor either the Northern or Southern Hemisphere. That’s because the moon has different characteristics in the two hemispheres, at opposite times of year. For example, the Harvest Moon is the full moon closest to the autumnal equinox. So it falls in September or October for the Northern Hemisphere, and it falls in March or April for the Southern Hemisphere.

About once every 19 years, February has no full moon at all.
Moreover, in 7 out of every 19 years, two full moons will fall in the same calendar month. And in a year where February has no full moon at all, like in the year 2018, you can actually have two full moons in January and two full moons in March, in which case you have 8 calendar months with 2 full moons in one 19-year lunar cycle. The second of the month’s two full moons is popularly referred to as a Blue Moon. Read about the July 31, 2015 Blue Moon.
