Question details

The organization needs to schedule project activities on weekends, but cannot find a way to include Saturdays and Sundays in the workweek.

How to Schedule Tasks on Weekends in Project for the Web

Product: Microsoft Project for the web
Device & OS: not provided
Scenario: Planning a project timeline for an organization that does not follow a standard Monday-to-Friday workweek.
Observed behavior: Project for the web does not provide a built-in, out-of-the-box option to schedule tasks or activities on weekends.

Before you start

Keep in mind that Microsoft Project for the web defaults to a standard 5-day workweek. To utilize a 7-day schedule, you will need to rely on Microsoft's alternative project environments like Project Online.

Solution 1Recommended

Use Project Online to Configure a 7-Day Working Week

Since Project for the web lacks weekend scheduling, switching to Project Online allows you to fully customize working days.

Project Online provides comprehensive calendar customization features that are not currently available in the simplified Project for the web interface. If your organization has access to it, you can alter the base calendar to include weekends.

Access Project Online

Log into your Microsoft 365 environment and launch Project Online instead of Project for the web.

Open Calendar Settings

Navigate to the project settings and look for the 'Change Working Time' option.

Modify the Workweek

Select the Work Weeks tab, click on Details, and highlight Saturday and Sunday. Set these days to specific working times to establish a 7-day workweek for your activities.

Environment Availability: This solution requires your Microsoft 365 subscription to include access to Project Online or the Project desktop client.

Report your need for weekend scheduling directly to the development team to prioritize future updates.

Frequently Asked Questions

Can I change the default working hours in Project for the web?

Currently, Project for the web relies on a fixed Monday-to-Friday background calendar. To define custom working hours or days, you need to use Project Online or the Project desktop application.

Will my project end dates adjust if I work on weekends in Project for the web?

No. Because Project for the web does not recognize weekends as working days, tasks spanning over a weekend will automatically have their duration pushed to the following Monday, increasing the calendar days taken.

Is Project Online being replaced by Project for the web?

While Microsoft is continuously adding features to Project for the web, Project Online remains available for complex project management needs, such as custom calendars and enterprise resource planning.
