Pre-fills into any week you haven't touched yet — a reminder, not a lock. Editing a week never changes this list; only this panel does.
Start must be less than or equal to End, both between 0 and 23.
Generates one page per week — up to 52 — each subtly labeled so a printed stack stays sortable. A week you've already filled in prints with its data; a blank week prints with just its dates.
