Calendar & Reminders
Add action items to any day, tick them off, and set a reminder time. If a task for today is still undone past its reminder, you'll see an alert. Switch between month and week views — everything saves in your browser.
How to use it
Add an action item
Click any day in the grid to select it, type your task in the box below, optionally pick a reminder time, and hit Add. Items show up right inside the calendar.
Mark done & remove
Tick the checkbox next to a task to mark it done (it gets struck through). Use the ✕ to remove it. Change the reminder time anytime.
Reminders
If a task dated today is still undone and the current time is past its reminder, a banner appears at the top. Tasks left undone on past days show as overdue. Enable notifications to also get a browser pop-up while the tab is open.
About this planner
Is my data private?
Yes — action items are stored only in your browser on this device. Nothing is uploaded unless you create a share link to copy your calendar elsewhere.
Month vs week view
Month view gives you the big picture; week view gives each day more room for its items. Use the arrows to move through time and Today to jump back.
Will reminders fire if the tab is closed?
No — this is a lightweight in-browser planner, so reminders and notifications only work while the tab is open. For hard alarms, also add the item to your phone's calendar.
