    description: 'Fixed 365-day year that keeps Feb 29 but drops Dec 31 in leap years
      — the Daymet convention. Not a CF calendar: distinct from `noleap` (which drops
      Feb 29) and from `gregorian` (which keeps Dec 31), so neither substitute preserves
      Daymet''s day-of-year alignment.'
