How to limit date fields between 2 values

Question

Hi I have two date fields and I can use min and max to limit them between two values. But what I wanna do is make it so that the user can only insert values before June 30th each year. So if a value is over that it gives an error. Right now I can do it but would have to change the year each year because I specify it as
Min june 30th 2011
Max june 30th 2012
I want this but so I don't have to change it to 2013 in a year.
Thanks and best regards

Answer 1

The validator should only allow dates in the range between June 30th this year and July 1st of next year. But with next year defined as current year + 1 year, not as a straight number which would have to be changed every year.
Does this make sense?
Here is a little background I have a vacations table and in it fields user, start, end, and ID. Now Start and End are the date fields. I have this query which gives a number of vacation days a user has spent excluding saturday and sunday. Now the problem in this query is that when the user inserts his vacation dates he can insert them for 10 years from now which messes with the query. So I was thinking if there was a way to limit the user to only be able to insert dates for the given business year which in my company (for some reason) goes from July 1st. That is the cut off date.
In other words in my company you have to use your vacation days by july 1st. Then you get the vacation days for next year which you can again use, until July 1st of next year. If you haven't used last year's vacation days by then you lose them. I just want to somehow incorporate this into the application.
Here is the sql query (and props to user Pollywog)

                    MAX (strt) strt,
                    MAX (finish) finish,

                            strt,
                            finish,
                            CASE
                               WHEN TO_CHAR (dy, 'day') LIKE 'saturday%' THEN 0
                               WHEN TO_CHAR (dy, 'day') LIKE 'sunday%' THEN 0
                               ELSE 1
                            END
                               dys

                           (dy [FOR d FROM 1 TO finish[0] - strt[0] INCREMENT 1] =
                                 (NVL (dy[CV () - 1], dy[CV ()]) + 1)))
           GROUP BY id
           ORDER BY id)
SELECT t.id,
       t.strt,
       t.finish,
