In my lab, we used to make the bleach solutions weekly, and keep them in
opaque bottles.  Probably daily is best, especially if you encounter a lot
of potentially biohazardous materials.  But, solutions made weekly should
work just fine.  We at times kept bleach solutions longer than a week, but
this was probably not a good practice to follow.
