first day of week

Hello,

I need the first day of an Isoweek as date.

I catch the week of a date with

week := to_number(TO_CHAR(mydate4,'IW'));

and the year with

year := to_number(to_char(mydate4,'YYYY'));

then I set

firstweek := week + 1;
firstyear := year -1;

Problems with week = 52 or 53 I will solve myself.

but now I need the date of the firstday in my Isoweek "firstweek" in the year "firstyear".

Who can help?
