Gantt Maker’s dual timeline system allows you to switch between date-based and hour-based planning instantly, giving you the flexibility to view your project at different levels of detail.

How to Switch Between Modes

1

Locate the Mode Selector

The timeline mode selector is located at the top of your Gantt chart interface, prominently displayed for easy access.
2

Click to Switch

Simply click on either “Date Mode” or “Hour Mode” to instantly transition between the two timeline views.
3

Review the New Layout

Your project will immediately redraw with the new timeline granularity, showing the same tasks in the selected mode.
The transition happens instantly with one click - no configuration required, no data loss, no waiting.

When to Switch Modes

Knowing when to use each mode helps you work more efficiently:

Switch to Date Mode When:

  • Starting a new project that will span weeks or months
  • Planning long-term milestones and deliverables
  • Coordinating multiple teams across extended timelines
  • Working with standard calendar schedules (Monday-Friday work weeks)
  • Presenting to stakeholders who think in calendar dates

Switch to Hour Mode When:

  • Entering a sprint or intensive phase requiring detailed scheduling
  • Coordinating time-sensitive deliverables where hours matter
  • Managing event logistics with precise timing requirements
  • Tracking billable hours for client work
  • Resolving scheduling conflicts that require hour-level adjustments

Example Workflow

A typical project might use both modes at different stages:
  1. Project Kickoff: Use Date Mode to plan the overall 3-month timeline and major milestones
  2. Sprint Planning: Switch to Hour Mode for the upcoming 2-week sprint to assign hourly tasks
  3. Mid-Project Review: Return to Date Mode to assess overall progress against calendar deadlines
  4. Launch Week: Switch to Hour Mode for precise coordination during the critical launch phase

Data Preservation During Switch

When you switch between modes, Gantt Maker preserves your project data:

What’s Preserved:

  • All tasks and assignments remain intact
  • Team member information including names, roles, and colors
  • Task descriptions and details are maintained
  • Progress status (Not Started, In Progress, Completed) carries over
  • Team member assignments stay connected to their tasks

What Changes:

  • Timeline granularity: Date mode shows days/weeks/months; Hour mode shows hours
  • Visual scale: The chart automatically adjusts to the appropriate time units
  • Time representation: Tasks display in the format appropriate for the selected mode

Auto-Saving

Gantt Maker automatically saves your work:
  • Changes are saved to local storage immediately
  • No manual save action required
  • Your data persists across browser sessions
  • Switching modes doesn’t trigger data loss
While switching modes is safe and preserves your data, the time units will be reinterpreted. A task spanning “3 units” in date mode (3 days) will appear differently than “3 units” in hour mode (3 hours). Review your timeline after switching to ensure the schedule makes sense in the new mode.

Comparing Outputs in Both Modes

Viewing your project in both modes provides different insights:

Date Mode Shows:

  • Overall project duration in calendar time
  • How work aligns with business days and weeks
  • Long-term resource allocation patterns
  • Milestone dates and deadline positions

Hour Mode Shows:

  • Detailed workload distribution during specific periods
  • Precise timing of task sequences
  • Hour-by-hour resource utilization
  • Exact scheduling conflicts

Using Both Views Together

Smart project managers leverage both views:
  • Plan in Date Mode for the big picture
  • Execute in Hour Mode for detailed coordination
  • Report using Date Mode for stakeholder communications
  • Optimize using Hour Mode to eliminate scheduling inefficiencies

One-Click Flexibility

The ability to switch between modes with a single click means:
  • No commitment to a single planning approach
  • Adapt to changing needs as your project evolves
  • Zoom in or out depending on what you need to see
  • No learning curve - both modes use the same intuitive interface
This flexibility sets Gantt Maker apart from traditional project management tools that lock you into a single view or require complex configuration to change perspectives.
Make it a habit to check your project in both modes. Date mode might reveal deadline pressures, while hour mode might uncover scheduling inefficiencies you wouldn’t notice at the daily level.

Responsive Across Devices

Mode switching works seamlessly across all devices:
  • Desktop: Full control with all features visible
  • Tablet: Touch-optimized mode selector
  • Mobile: Simplified interface maintains mode switching capability
Your timeline mode preference is saved, so when you return to your project on a different device, it opens in your last-used mode.
