About this tool
Plan a seven-day week in time blocks, see each day's load and free hours, and get warned when two blocks clash.
The Weekly Planner turns a list of tasks into a dated seven-day time-block schedule and tells you, in minutes, how full each day already is. It works out every day's load as blocked minutes divided by your waking window (08:00-22:00 by default), flags any two blocks that overlap using the standard interval test — a.start < b.end and b.start < a.end — and totals your week by category. It suits anyone doing time blocking, week-ahead reviews or capacity planning, and everything is stored in your own browser.

Any two blocks that overlap on the same day are highlighted, using exact minute-from-midnight comparison.
Overlapping blocks are counted once when free hours are measured, so the remaining time is real.
The whole week is saved in your browser's local storage — nothing is uploaded to a server.
Keep planned blocks under about 85% of your waking window — roughly 12 hours out of a 14-hour 08:00-22:00 day. The planner marks a day overloaded above that, because the remaining time is what absorbs overruns, transitions and interruptions.
It uses the standard interval overlap test: block A and block B clash when A starts before B ends and B starts before A ends. A 09:00-11:00 block and a 10:30-11:00 block therefore clash; a 09:00-10:30 block and a 10:30-11:00 block do not, since touching edges are not an overlap.
Yes. The week start toggle switches between Monday and Sunday, and the planner recomputes the seven dates from the date you are viewing: start of week = date minus ((weekday - week start + 7) mod 7) days.
Yes. The plan is written to your browser's local storage on this device only. Clearing site data or using a different browser or device starts you with an empty week again.
