Weekly capacity calculator
Subtract meetings, administration, contingency and transition time from your workweek. Compare remaining capacity with estimated task effort.
Practical planning resources
Time-block buffer planner
Try a one-day focus plan around sample meetings. Reserve at least 15 minutes between tasks and meetings, and see which work cannot fit.
Private by design: this calculator makes no network request with your inputs, uses no local storage and does not put values in the URL. Refreshing clears your entries. Use numerical examples rather than personal or confidential information.
How the sample planner works
Enter only meeting times in one local day. The planner tries your focus blocks in the order listed, chooses the earliest available 15-minute start, and leaves the selected minimum gap before and after every supplied meeting and every placed focus block. Overlapping meetings are treated as occupied time, not silently deleted. A block that cannot fit is reported as unplaced.
A worked example
With a 09:00–17:00 day, meetings at 10:00–11:00 and 13:00–14:00, and a 15-minute gap, a 60-minute task first fits at 11:15–12:15. A 120-minute task then fits at 14:15–16:15. A later 45-minute task can use 09:00–09:45. The output is chronological; the numbers retain your original priority order. A gap exactly equal to 15 minutes is valid.
This is a simple first-fit illustration, not a globally optimal schedule. Different task ordering may place more work. It does not split a block, handle multiple days, travel, daylight-saving changes, priorities inferred from text or provider-side edits. Break longer efforts into sessions of no more than 120 minutes before entering them.
Use the result safely
A buffer protects transitions but does not make existing meetings conflict-free. Include breaks or unavailable periods as meeting intervals if they should block time. This educational calculator lets you explore a custom day; that does not change the application's current weekday 09:00–17:00 scheduling window. Nothing is exported to a calendar, and no invitations are sent.
