Find Current Date Time Span SQL

Any body have an Idea on this... Last problem of my Calendar Application.

To keep my calendar loading fast and efficent I have a SP that loads data to a datatable to read from c#.

My sp reads this

(
@.ID int,
@.DateStart datetime,
@.DateEnd datetime
)
AS

SELECT JobDateStart, JobDateEnd, EstimateDate, cLastName,
cCity, ContractPrice, JobDescription, Status
FROM Customers
WHERE (ID = @.ID AND JobDateStart Between @.DateStart AND @.DateEnd + 1
OR JobDateEnd Between @.DateStart AND @.DateEnd + 1)

Now My problem is that the DateStart and DateEnd values are used to pull information from a DB. So lets say that I have a job that starts on November 30th and ends on January 3rd.
My calendar will display the record on the 30th day of Nov and on the 1st through 3rd fo Jan, however when I look at December there is NO DATA there. which is the expected result because the dates do not fall within the start and ends dates.

My question is how query the database to pull back my month spanding record without pulling back all the data in the database for performace?

My thought is something like the date span falls into the range between the start and end, but I cannot find anything????? Please help, I know it is probaly simple right??Found the answer, just took THINKING LESS rather than more..

add and OR statement like this, it will get the 1 day events and current month event and the spanning events.

SELECT JobDateStart, JobDateEnd, EstimateDate, cLastName,
cCity, ContractPrice, JobDescription, Status
FROM Customers
WHERE (ID = @.ID AND
/*FIX SPANNING MONTHS / YEAR JOBS*/
@.DateStart BETWEEN JobDateStart AND JobDateEnd +1
/*SELECT 1 DAY OR 1 MONTH JOBS*/
OR JobDateStart Between @.DateStart AND @.DateEnd + 1)

It really was that easy. Less load on the db so I can loop through the DataTable and do my sorting with no effect on the DB.
