What Is a Timeline Calendar?
A standard calendar shows you when. A Gantt chart shows you what. A timeline calendar shows both at the same time.
Horizontal Project Roadmap
Active projects span across the top as colored bars. Milestones sit as markers at fixed dates. See which projects overlap and when they converge.
Vertical Daily Calendar
Your hour-by-hour schedule lives below the roadmap. Each time block is color-coded to match the project lane above it, so the link is always visible.
Goal Alignment View
When a daily task is connected to an active milestone, a line runs between them. When there is no line, your day is busy but not moving anything forward.
Most people use a calendar for scheduling and a separate tool for project planning
That works until you need to answer a simple question: does what I'm doing today actually move my project forward? Switching between tools to find out breaks focus and makes the answer easy to ignore.
Didon's timeline calendar keeps both views on the same screen. The project roadmap sits above the daily planner, and every time block is color-coded to the project it belongs to.
Standard calendar
Shows you when you are scheduled, but has no concept of which project or goal the time belongs to.
Gantt chart or roadmap
Shows project phases and milestones, but cannot block time in your day or warn you when capacity is exceeded.
Timeline calendar (Didon)
Both in one screen. Your daily time blocks are visible alongside the project roadmap they belong to.
Timeline Calendar vs Other Tools
Most planning tools make you choose between a roadmap and a daily schedule. Didon is the only one with both in a single view.
What Is a Timeline Calendar?
A timeline calendar merges a daily planner and a project roadmap into one view. The horizontal axis maps your macro timeline (weeks, months, project phases), while the vertical axis breaks each day into time slots. You see the roadmap and the schedule at the same time, on the same screen.
A Gantt chart tells you that a project launches in six weeks. A daily calendar tells you Thursday at 2 PM is free. A timeline calendar connects those two facts so your afternoon time block is visibly tied to a real milestone, not just a placeholder.
Timeline Calendar vs Daily Planner vs Gantt Chart
A daily planner focuses on today. A Gantt chart focuses on the project. Neither shows you whether today's tasks are actually moving your project forward. A timeline calendar keeps both zoom levels on screen so you can answer that question without switching tools.
Didon's timeline calendar updates in real time as you complete tasks. Milestones shift, project bars reflect actual progress, and the link between your daily schedule and your long-term roadmap stays accurate.
