Daily Planner — Time-Block Scheduler

Press Load Sample and the planner populates with a developer workday: Stand-up at 09:00, deep work at 10:00, lunch at 12:00, code review at 13:00, team sync at 16:00 and end-of-day wrap at 18:00. Eight time blocks you can immediately tick off, edit, or replace with your own day. Everything saves to your browser automatically as you type, so closing the tab and coming back still shows today's plan exactly as you left it.

Each block has a free-form time field and a task field. The time can be a 24-hour clock value like 09:00 or a label like Morning or After lunch. Tick the circle on the left to mark a block done; the progress bar at the top updates immediately and the finished block fades out of the way without disappearing, so you can still read the full day at a glance.

The Controls

• Add block inserts a new slot pre-filled with the current time, so your next block always starts at the right point in the day rather than at midnight.
• Sort by time reorders blocks whose time field parses as HH:MM numerically. Blocks with free-text labels like Afternoon stay in their insertion order at the bottom. Mixed plans sort sensibly rather than breaking on non-numeric values.
• Copy writes the whole day as a plain-text summary, one line per block in the form 09:00 — Stand-up + review pull requests, with a check mark appended to done items. Ready to paste into a message or a standup update.
• .md downloads the same content as a Markdown checkbox file (- [x] … for done, - [ ] …for pending), named daily-plan-YYYY-MM-DD.md, compatible with Obsidian, Notion or any Markdown system.
• Clear removes all blocks for the active day without touching any other date.
• The history sidebar appears once a second date has entries. It shows up to 7 past dates; click any one to switch to that day and review or edit it.

Storage and Limits

• Plans are stored in localStorage under the key daily-planner-v1. Nothing is sent to a server. Private or incognito browsing sessions start empty and do not persist across tabs.
• A single day supports up to 48 blocks before the add button disappears. In practice, a useful plan has 6 to 12 blocks; the limit guards against accidental data growth.
• Plans are keyed by ISO date, so “Today” and “Yesterday” always show the right day even when you open the tool just past midnight.
• The history sidebar shows at most 7 dates. Older entries remain in storage but do not appear in the sidebar. Clearing a day removes its blocks, and the date vanishes from the sidebar on the next load once it has zero blocks.
