How to Set a Seven-Day Workweek in Microsoft Project
Product
Microsoft Project
Device & OS
not provided
Scenario
Configuring project calendar schedules to reflect weekend working hours or continuous round-the-clock operations.
Observed behavior
Changes to the custom seven-day calendar sometimes fail to appear on the Gantt chart due to incorrect working-time configurations or mismatched timescale settings.
Before you start

Determine whether your project requires a standard 8-hour workday spread across seven days or a continuous 24-hour schedule, as the configuration steps for each differ slightly.

Solution 1Recommended

Configure the Seven-Day Workweek in the Change Working Time Dialog

Use the Change Working Time feature to define customized working days and hours from Sunday through Saturday.

Microsoft Project uses a standard 5-day workweek by default. To schedule tasks over the weekend, you must explicitly modify the project calendar to recognize Saturday and Sunday as working days.

1
Open Change Working Time

Navigate to the 'Project' tab on the top ribbon and click on 'Change Working Time' in the Properties group.

2
Select the Project Calendar

In the dialog box, use the 'For calendar' dropdown list to select the specific project calendar you wish to modify (usually 'Standard').

3
Modify the Work Weeks Details

Click on the 'Work Weeks' tab in the lower half of the dialog, select the '[Default]' entry, and click the 'Details...' button.

4
Set Seven-Day Working Times

Select all days from Sunday through Saturday on the left. Choose 'Set day(s) to these specific working times:' and input your required shift hours (e.g., 8:00 AM to 5:00 PM for normal hours, or 12:00 AM to 12:00 AM for a 24-hour continuous schedule). Click 'OK'.

Verify Task Calendars: Ensure that individual tasks are using the newly updated project calendar and do not have conflicting custom task calendars assigned in their Advanced properties.

Frequently Asked Questions

Why is my seven-day workweek not showing on the Gantt chart?

If your Gantt chart still shows gray bands on weekends, you need to apply your updated calendar to the visual timescale. Right-click the timescale bar, select 'Timescale', go to the 'Nonworking Time' tab, and select your custom seven-day calendar from the dropdown list.

What is the difference between a seven-day workweek and a 24-hour calendar?

A seven-day workweek means work occurs every day from Sunday to Saturday, typically for standard hours (like 8 hours a day). A 24-hour calendar means continuous work around the clock (midnight to midnight) without any nonworking breaks or offline hours.

Where can I find the Timescale dialog box in Microsoft Project?

The Timescale dialog box can be accessed by double-clicking the gray shaded bands containing dates at the top of the Gantt Chart view, or by right-clicking those bands and selecting 'Timescale' from the menu.

Can I apply the seven-day workweek only to specific tasks instead of the whole project?

Yes. You can assign a custom calendar to an individual task by double-clicking the task, navigating to the 'Advanced' tab in the Task Information dialog, and selecting your seven-day calendar from the 'Calendar' dropdown box.
