  This can easily be achieved by using NTILE.

  DECLARE @parts INT = 5;

  SELECT

  StartDate= MIN([Date])

  ,EndDate= MAX([Date])

  FROM

  (

  SELECT

  [Date]

  ,Parts = NTILE(@parts) OVER (ORDER BY [DateOfYear])

  FROM [dbo].[myDateTable]

  WHERE [Year] = 2014

  ) tmp

  GROUP BY Parts;
