Start with the boundary
Set when work starts and must end. The finish time is a constraint, not a target to stretch after you see how much is on the list.
Protect your finish time
A fixed finish time becomes useful when it shapes the plan before the tasks are scheduled. Budget the available time honestly, then choose what will happen inside it and what will wait.
A workflow you can use
Subtract commitments first
Include meetings, travel and other fixed time in the commitment total. Account for breaks rather than calling them spare capacity.
Estimate the actual work
Describe tasks at a size you can estimate. 'Prepare the deck outline' is easier to schedule than 'finish launch'.
Move the overflow deliberately
When the tool says a task does not fit, decide whether to shrink its scope, change priorities or move it. Do not erase transitions to make the numbers look better.
Put the idea into practice
A concrete example
A six-hour window with two hours of commitments does not contain six hours of project work. Add breaks and transitions, then decide which of the remaining tasks deserves the available time.
When to use the iPhone app
Daypart's listing describes realistic plans around an existing calendar, transition time and firm personal boundaries. Its stated workflow makes room for work rather than treating every open minute as available focus.
Know the boundary
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.
Day capacity and time-block planner
A plan only fits when it accounts for fixed commitments, task duration and transitions. Enter your working window and priorities to see which tasks fit and which need another day. The tool shows overflow instead of squeezing every task into the schedule.
Enter tasks in priority order. Fixed commitments are a total duration deducted from the window; this page cannot place tasks around individual meeting times. The remaining blocks are a capacity plan, not a synced calendar.
