Light Months

The Twelve Light Months

If you want you can use the 12 months of the Light Calendar. They are aligned with the Light Seasons and run from New February (Neufebruar) to New January (Neujanuar).

Month Names (English / German)

1. New February (Neufebru) - 29 days (Start of Early Spring in total ~90 days)
2. New March (Neumärz) - 31 days
3. New April (Neuapril) - 30 days
4. New May (Neumai) - 32 days (Start of Early Summer ~94 days)
5. New June (Neujuni) - 31 days
6. New July (Neujul) - 31 days
7. New August (Neuaugus) - 31 days (Start of Early Autumn ~93 days)

12. New January (Neujanu) - 30/31 days (leap month)

Month Lengths

The Light Calendar uses balanced, variable month lengths of 28-32 days. These lengths are not assigned arbitrarily, but follow the internal symmetry of the light year.

Across the four light seasons, the months form a repeating structural pattern (29–31–30 | 32–31–31 | 31–31–31 | 28–30–30/31), ensuring that the calendar remains evenly distributed around the solar turning points. Leap adjustment is applied exclusively at the end of the year, in New January, leaving the internal structure of the year unchanged.

Purpose

Month lengths in the Light Calendar are determined by light symmetry and astronomical anchoring, not by historical contingencies inherited from the Roman calendar. As a direct consequence of the year definition, all four primary solar events occur consistently on the 16th or 17th day of their respective Light Months.
