Why build your calendar here instead of a spreadsheet This tool works for work schedules and shift planning, editorial and content calendars, project milestone tracking, and personal organization. Choose any month and year from the dropdowns and the grid re-renders with correct weekday offsets and leap years. Click a day to add an event with a title, category, optional time and notes. Drag a chip to another day to reschedule. Export everything to CSV for your team, or print a clean monthly sheet. Your data stays in your browser via local storage.
