Full moon calendar 2025 and sleep: Do you sleep worse at full moon?

So some people report that you can sleep worse or not in full moon. This is scientifically controversial. Diploma psychologist Jürgen Zulley told our editorial team that the moon was not to blame for bad sleep.

A study in the specialist magazine Science Advances on the other hand, has found a connection between the moon and sleep. In one study by scientists from the USA And Argentina was examined the sleep behavior of 98 indigenous inhabitants in Argentina and 464 US students from Seattle. The result according to the study on the connection between the full moon and sleep: In both cases, people later went to bed three to five days before the full moon and slept shorter. The less electrical light there was, the more clearly the effect should have been.

Full moon: cut hair, clean windows, work in the garden – what’s it?

Cutting hair, cleaning work in the garden or window – some people align everyday things according to the lunar calendar and are therefore interested in the dates for the full moon 2025. Science could not yet definitely answer whether this is pure superstition. There are more detailed data on the question of whether the moon can affect menstruation.

In another international study on moon phases in the specialist magazine Science Advances the menstrual cycles of 22 women over 15 years were evaluated. It came to the conclusion that the moon could play a role in the insertion of menstruation. Both the brightness and the influence of gravity are held responsible for this.

Moon phases explained: How do new moon, crescent moon and full moon in the sky arise?

• New moon: At Neumond, the moon is between earth and the sun. This means that the sun’s rays only reach the side turned away from the earth. Therefore, the moon cannot be seen or at least poorly seen from the earth.
• increasing crescent moon (first quarter): In this phase of moon, half of the sun is illuminated by the sun on the earth. This then appears as a crescent moon, as it is generally called. Astronomers, on the other hand, speak of the first quarter.
• Full moon: In the event of a full moon, the sun, earth and moon are back on a line. This time the sun and moon are located on opposite sides. This means that the moon side visible from earth is fully irradiated. Therefore, the entire moon can be seen.
• Detaching crescent moon (last quarter): In this moon phase, the sun shines only half of a lunar side that is facing the earth. Compared to the increasing crescent moon, this is the other half. Astronomers speak of the last quarter, since the moon has covered 75 percent of its orbit since the last new moon.

By the way: That the moon is sometimes visible during the dayalso depends on the moon phases.

Supermond 2025: What is a Supermond or Blue Moon?

In the case of full moon, the moon logically has its maximum brightness. In the case of sky bodies, the apparent brightness is given with a value for magnitude (MAG). With the full moon, this is around -12.5 to -13 Mag. For comparison: the sunlight is about 400,000 times as bright. The brightness of the moon also depends on how close it is to the earth. Due to the elliptical orbits, the distance fluctuates.

If the full moon of the earth is particularly close, a « supermond » is colloquially talked about. The term « Blue Moon » for a second full moon comes from English within one month. Of course, the moon is not blue. The super moon is defined as a full moon that is a maximum of 360,000 kilometers from the center of the earth.

Blood moon and total lunar eclipse: Date for Germany

Sometimes the full moon appears as a red « blood moon » – this is the case with a total lunar eclipse. A total lunar eclipse occurs when the moon enters the earth’s core shadows. Since the long -wave red rays can penetrate the atmosphere, the full moon appears reddish. When is the next total lunar eclipse in Germany? Here you can find the date and time:

Jewish and Islamic calendar are based on the lunar calendar

In Islam and Judaism, the calendar is based and the months on the lunar calendar. Also the Dates for Jewish holidays and the Dates for Islamic holidays This depends on the moon.

In Islam, the festivals therefore fall over time in different seasons. This is not the case with Judaism: Here an additional month is regularly inserted to correct the difference to the usual solar year through these leaps.
