Worth knowing
Where does the name ‘Cold Moon"?
Cold Moon (English Cold Moon) is a traditional full moon name associated with December. A name referring to the long, cold nights of early winter. This is a culturalname, not an astronomical one - popularised by the American Farmers’ Almanac.
Full moon in December 2021 occurs on 19 December at 05:35 Polish local time (CET), when the disc is illuminated by almost 100%. The Moon rises around dusk and shines almost all night - in winter it can appear especially bright against snow and long nights. A good time for observing the Moon, but also a night when bright light may make falling asleep harder.
Prepare your sleep for a bright night
- Dim bright bedroom lights an hour before bed.
- Cover your windows to keep outside light out.
- Limit blue light from screens in the evening - evening glasses can help.
- If you cannot darken the room fully, an eye mask can help.
