Time Block Planner

About this tool & what it can't do

• Local only: your schedule is saved in this browser's storage only. It is not synced to an account or other devices, and clearing your browser data will erase it permanently.
• 15-minute grid: all block times are snapped to 15-minute increments. You can't create or move a block to e.g. 9:07.
• 15-minute minimum: a block can't be shorter than 15 minutes.
• No overnight blocks: a block must start and end on the same day (it can't cross midnight). For overnight tasks, create two separate blocks.
• Dragging moves a block up/down within its own day only. To move a block to a different day, tap the pencil (✎) icon on it and change the date in the editor.
• Overlapping blocks are shown side-by-side (narrower) rather than stacked on top of each other, so nothing gets hidden — but many overlaps on one day can make blocks quite narrow.
• Week view always starts on Monday. This is fixed and can't be changed.
• Templates apply to today's date only and will replace any blocks already on today, regardless of which days you're currently viewing.
• "Clear Today" removes only today's blocks. "Clear All" permanently deletes every block you've ever created, on every date.
• The current-time indicator refreshes once a minute, not continuously.
