SQL Substring

I need to parse out of this string Year-MonthName-Day

The result should look like this

My issue is that I am using 2 different patindex because of the single digit and two digit days. I would like 1 Patindex that will account for both scenarios.  

Once that is done add the "-Day". If the day is single digit 04 else 18

Sample code
Declare @LinkSource varchar(8000), @LinkSource2 varchar(8000)

Set @LinkSource = 'Testing -Mod +190 -8.5   +9.6    Tester-legoland-date-october-18-2015'
Set @LinkSource2 = 'Testing -Mod +120 -6.5   +7.5    Tester-legoland-date-october-4-2015'

right(@LinkSource,4)+'-'+substring(@LinkSource,charindex('date-',@LinkSource,0)+5,Len(@LinkSource)-patindex('%-[0-9][0-9]-%',@LinkSource))--charindex('-',@LinkSource,charindex('odds-',@LinkSource,0)) )
,right(@LinkSource2,4)+'-'+substring(@LinkSource2,charindex('date-',@LinkSource2,0)+5,Len(@LinkSource2)-patindex('%-[0-9]-%',@LinkSource2)+1)--charindex('-',@LinkSource,charindex('odds-',@LinkSource,0)) )

If there is a better way to trim month and day out I am all ears.

You can try this

Declare @LinkSource varchar(8000)

Set @LinkSource = 'Testing -235 +190 -3.5   +3.5    Tester-legoland-date-october-18-2015'
--Set @LinkSource = 'Testing -235 +190 -3.5   +3.5    Tester-legoland-date-october-4-2015'

SET @LinkSource = SUBSTRING(@LinkSource,CHARINDEX('DATE',@LinkSource)+5,LEN(@LinkSource))                         

+'-'+ CASE WHEN SUBSTRING(@LinkSource,CHARINDEX('-',@LinkSource)+1,2) LIKE '%-%' THEN
'0'+ REPLACE(SUBSTRING(@LinkSource,CHARINDEX('-',@LinkSource)+1,2),'-','') ELSE 
REPLACE(SUBSTRING(@LinkSource,CHARINDEX('-',@LinkSource)+1,2),'-','')  END Dates

I added 2 auxiliar variables since I don't know if you want to change the values of the original values but you can avoid those 2 auxiliar variables and work only with the original ones if isn't important to you to keep the original values:
Declare @LinkSource varchar(8000), @LinkSource2 varchar(8000)

Set @LinkSource = 'Testing -Mod +190 -8.5   +9.6    Tester-legoland-date-october-18-2015'
Set @LinkSource2 = 'Testing -Mod +120 -6.5   +7.5    Tester-legoland-date-october-4-2015'

Declare @LinkSourceAux varchar(8000), @LinkSource2Aux varchar(8000)

SET @LinkSourceAux = REPLACE(RIGHT(@LinkSource, LEN(@LinkSource)-CHARINDEX('date-', @LinkSource,1)-4),'-','.')
SET @LinkSource2Aux = REPLACE(RIGHT(@LinkSource2, LEN(@LinkSource2)-CHARINDEX('date-', @LinkSource2,1)-4),'-','.')

SELECT PARSENAME(@LinkSourceAux,1) + '-' + PARSENAME(@LinkSourceAux,3) + '-' + RIGHT('0'+PARSENAME(@LinkSourceAux,2),2), 
	PARSENAME(@LinkSource2Aux,1) + '-' + PARSENAME(@LinkSource2Aux,3) + '-' + RIGHT('0'+PARSENAME(@LinkSource2Aux,2),2)
