Help with this logic

Question

Dear experts;
I have two tables similar to this below
create table t1
   place varchar(1000),
   start_time date,
    end_time date
insert into t1 values ('NewYork', to_date('2013-01-01', 'YYYY-DD-MM'));
create table t2
  date_list date,
  week_description varchar(1000)
insert into t2 values (to_date('2013-01-01', 'YYYY-DD-MM'), 'week 1('2013-01-01' - '2013-02-01)')
insert into t2 values (to_date('2013-02-01', 'YYYY-DD-MM'), 'week 1('2013-01-01' - '2013-02-01)')
insert into t2 values (to_date('2013-03-01', 'YYYY-DD-MM'), 'week 2('2013-03-01' - '2013-04-01)')
insert into t2 values (to_date('2013-04-01', 'YYYY-DD-MM'), 'week 2('2013-03-01' - '2013-04-01)')I would like a simple logic that will give me an opportunity to insert new values in my t1 table for a particular given week_description
So take for instance, we have only one row right now in t1, which is NewYork, 2013-01-01
I want a case where I can get week 2 information from t2, so that t1 will end up with the following result.
NewYork, 2013-01-01
NewYork, 2013-03-01
NewYork, 2013-04-01
Kindly note, the week 2 will always be a user input. All help is appreciated.

The place will always be gotten from t1 unfortunatelyHow?
Does T1 always have only 1 place?
ie
select distinct place from T1??
What happens when we add:
insert into t1 values ( 'Boston', sysdate );??
How do I derive the Place?
