Sleep
Studies show a statistically significant association between full moon and reduced sleep quality. Individual effects vary widely.
Moon Calendar - 2026
Thirteen full moons occur in 2026, with May having two (the second is colloquially called a 'Blue Moon'). Times are computed with Jean Meeus' algorithm (accuracy +/-1-2 minutes) and cross-checked against the NASA database. CET = winter (UTC+1), CEST = summer (UTC+2).
The twelve traditional names come from Native American and Farmers' Almanac traditions and describe seasonal phenomena.

Studies show a statistically significant association between full moon and reduced sleep quality. Individual effects vary widely.
Traditionally, the full moon is favorable for harvesting root vegetables and fruit - plant sap is said to rise.
Many hairdressers recommend the full moon for powerful cuts that grow back faster.
The first full moon of 2026 is on January 3 at 11:04 CET. Twelve more follow - one per month, plus a second on May 31 (Blue Moon).
A Blue Moon is the second full moon within a calendar month. In 2026 this occurs on May 31.
Times are calculated with the standard algorithm from Jean Meeus' 'Astronomical Algorithms' (chapter 49). Accuracy is plus/minus 1-2 minutes against actual astronomical events.
Several studies (e.g. Cajochen et al., 2013) show a statistically significant association between full moon and reduced sleep quality, though effects vary widely between individuals.
