There is a micromoon on May 31stFull moon in the zodiac sign Sagittarius – what the “Blue Moon” means for the zodiac signs

On the 1st and 31st: Why are there two full moons in May 2026?

On May 31st around 10:45 a.m. the moon can be seen in full over Germany again – for the second time in a month. And that's exactly what's special, because there is actually only one full moon in each month and twelve in a year. So why are there two full moons in May of all days and a total of 13 in 2026?

The time from full moon to full moon is about 29.5 days, like that Astro portal Starwalk explained. However, since our months have up to 31 days, a difference arises. And this means, on the one hand, that there are always full moons on different dates and, on the other hand, that there are always two full moons in a month and therefore 13 instead of twelve full moons in a year.

Why is the second full moon in May called the “Blue Moon”?

All full moons have very specific names that were “traditionally chosen by our ancestors so that they reflect the typical activity that could be observed at the time,” explained astrologer Phi Weber in an earlier RTL interview. For example, the February full moon is called the Wolf Moon or the September full moon is called the Harvest Moon.

The second full moon in May is called the “Blue Moon” and it has nothing to do with the season and nothing to do with the color in which it appears. Rather: Whenever there are two full moons in a month, the second of them is called the “Blue Moon” – regardless of which month it occurs in. The name is said to go back to the American saying “Once in a blue moon,” as Starwalk further explains. The saying roughly corresponds to the one we know “Every jubilee year” and therefore means a rare event.

How often does the “Blue Moon” occur?

And the fact that the “Blue Moon” is exactly that – a rare event – ​​is proven by its last and next occurrence: The last “Blue Moon” was in August 2024 and, according to the Astro portal, the next one will not occur until December 2028. “Blue moons” occur approximately every two and a half years.
