The September 2026 lunar calendar in Argentina

The September 2026 lunar calendar shows when the Moon will pass through its different phases during the ninth month of the year. The full Moon, when the satellite can be seen in its entirety, will occur on Sept. 28.

The new Moon will take place during the second week of September, while the full Moon will be visible in the final week. The dates of lunar phases can differ from the regular calendar because the lunar cycle lasts about 28 days and changes from month to month.

Astronomy enthusiasts and people interested in esoteric practices follow the Moon’s monthly changes for different activities. Some believe its movements can affect daily life and people’s moods. One example is hair cutting, which some believe the Moon can influence. The article also notes the many myths surrounding the phenomenon.

According to Argentina’s Naval Hydrographic Service, the lunar phases correspond to precise moments when the Earth-Moon and Earth-Sun directions form angles of 0, 90, 180 and 270 degrees. The phases therefore do not last a set number of days, as is sometimes mistakenly believed. They occur at specific moments.

September’s full Moon is called the Harvest Moon. The name comes from Indigenous peoples of North America, who tracked the passage of time through the Moon’s phases. It refers to the full Moon closest to the equinox, which marks the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere. The name reflects its usual coincidence with the harvest season.
