Here you go this is all combined. It finds the first monday going forward from the current date

Then gets the past 6 months worth of mondays from that date.


--datepart = Sunday = 1, Saturday = 7
 
DECLARE @WorkingDate as datetime
DECLARE @FirstMondayDate as datetime
DECLARE @EndDate as datetime
DECLARE @DayOfWeekLookingFor as int
 
-- set to the first StartDate you want for the first Sunday
Set @WorkingDate = GetDate()
Set @FirstMondayDate = ''
 
-- for monday
Set @DayOfWeekLookingFor = 2 
 
-- do this to find the number of the days of week found 
while @FirstMondayDate = ''
	Begin 
		-- if day of week matches what we are looking for add one to counter
		IF datepart(weekday, @WorkingDate) = @DayOfWeekLookingFor
			Set @FirstMondayDate = @WorkingDate
		
		-- increment date by one day and loop again
		Set @WorkingDate = DATEADD (dd, 1, @WorkingDate)		
		
	end
 
-- set the enddate to 6 months from the first monday we found
Set @EndDate = DATEADD (mm, -6, GetDate())
 
-- set working date to the first monday date we found above for next loop
Set @WorkingDate = @FirstMondayDate
 
 
 
-- this loops through from the first day found above to the last one requested
-- do till the end date you wnat reached
while @WorkingDate > @EndDate
        Begin 
                -- insert current working Monday date, and then add 6 to that to get the next saturday (ending dat)
                --Insert Into DatabaseTableName
                --(MondayDate)
                --Values(@WorkingDate, DATEADD (dd, 7, @WorkingDate))
				
				-- just select the date
                select @WorkingDate
 
                -- increment sunday date for next loop
                Set @WorkingDate = DATEADD (dd, -7, @WorkingDate)                
                --print @WorkingDate
        end
