Solution 1Recommended

Emphasize Non-Working Time Over Task Bars

While you cannot completely hide non-working hours, you can bring the non-working time shading to the front to clearly highlight working periods.

By default, Microsoft Project draws task bars over non-working time, making them look continuous. Changing the display order allows the gray non-working bands to visually break up the task bars, highlighting exactly when the working hours occur.

1
Open Timescale Settings

Double-click the time scale area at the top of your Gantt chart view.

2
Navigate to Non-working Time

Click on the 'Non-working time' tab in the Timescale dialog box.

3
Bring to Front

Select the option 'Draw in front of task bars' and click OK to apply the changes.

Emphasize Non-Working Time Over Task Bars
Visual Clarity: Your task bars will now visually break during weekends and non-working hours, making actual working durations much easier to read.

Frequently Asked Questions

Can I completely hide non-working weekends in a Microsoft Project Gantt chart?

No, non-working time cannot be completely removed or hidden from the timescale in standard Gantt chart views. However, you can format it to draw in front of task bars to heavily emphasize your working hours.

Why do my task bars look continuous over non-working days?

By default, task bars are drawn over the background shading of non-working days. You can change this by double-clicking the timescale, navigating to the Non-working time tab, and selecting 'Draw in front of task bars'.

How do I change the default working hours for my project?

To adjust the actual working hours and days, go to the Project tab on the ribbon, click 'Change Working Time', and modify the default work weeks or add specific exceptions.
