Read the allocation rule
The browser checks whole tasks against each day's remaining capacity. It does not split a 300-minute task between two 150-minute gaps. An unallocated row is visible so you can make that decision yourself.
Split the work at a useful boundary
A whole task can fail to fit any day even when the week has enough total spare minutes. That is a reason to examine scope and handoffs, not silently fragment the task into unrelated calendar scraps.
Put it into practice
Find meaningful deliverables
If splitting is appropriate, name parts you can complete and resume coherently, such as outlining, drafting and reviewing. Include preparation or handoff time in the estimates rather than pretending the pieces have no overhead.
Replan with the new scope
Replace the original task with the chosen parts in your own list and rerun the budget. Check that the parts still cover the actual deliverable. The tool does not infer dependencies, so you must keep work that depends on an earlier part in a sensible order.
A worked example
A long report may become an outline, a draft and a review. Three arbitrary equal time blocks with the same vague name do not necessarily provide equally useful stopping points.
Weekly task capacity allocation with visible overflow
A task list can exceed a week even when every day looks open. Enter each day's window, fixed commitments and breaks, then place whole tasks in your priority order. The planner assigns each task to the first entered day with enough remaining capacity and leaves oversized work visible as overflow.
This is a duration budget, not calendar integration or deadline-aware scheduling. Tasks are not split automatically. Transition time is added between tasks placed on the same day. A negative starting capacity means entered commitments and breaks exceed that day's window.

What to keep in mind
This web planner uses the commitments and estimates you enter; it does not read your calendar. Its schedule is arithmetic, not a personalized assessment of energy or a promise that a task will finish on time.
