How to Make Saturday and Sunday Workdays in Project Web App

Product: Project Web App (PWA)
Device & OS: not provided
Scenario: Scheduling tasks or allocating resource hours that require Saturday and Sunday work.
Observed behavior: Project Web automatically moves weekend deadlines to the nearest working day (usually Monday), even after individual resource hours are modified.

Before you start

Ensure you have administrator permissions in Project Web App (PWA), as creating or editing Enterprise Calendars requires admin rights and affects resource scheduling globally.

Configure and Assign an Enterprise Calendar for Weekend Work

Create or modify a base calendar in PWA settings to explicitly include Saturdays and Sundays as working days, then assign it to the necessary resources.

By default, standard enterprise calendars treat weekends as non-working time. To fix the shifting deadlines, you must update the global Enterprise Calendar and ensure the specific resource is using it as their Base Calendar.

Access PWA Settings

Open Project Web App, click the gear icon in the top right corner to open settings, and select 'PWA Settings'.

Open Enterprise Calendars

Under the 'Enterprise Data' section, locate and click on 'Enterprise Calendars'.

Edit or Create a Calendar

Select an existing calendar and click 'Edit', or click 'New Calendar' to create a custom schedule specifically for weekend workers.

Set Weekends as Working Days

In the calendar configuration window, navigate to the Work Weeks tab, click on Details, select both Saturday and Sunday, and set them to your required working times. Save the calendar.

Assign Calendar to Resources

Go to the Resources page in PWA, select and edit the relevant resource, and change their 'Base Calendar' dropdown to the newly configured calendar. Save your changes.

Configure and Assign an Enterprise Calendar for Weekend Work

Project Recalculation: After applying the new Base Calendar, Project Web will recalculate timelines and your weekend deadlines will no longer shift to Monday.

Frequently Asked Questions

Why do my task dates automatically change to Monday in Project Web?

By default, the standard enterprise calendar in Project Web sets Saturday and Sunday as non-working days. If a task is scheduled to finish on a weekend, the scheduling engine automatically pushes the deadline to the next available working day.

Can I change working days for just one specific project resource?

Yes. You can create a custom base calendar in Enterprise Calendars with weekend workdays enabled, and then assign that specific calendar only to the resources who work on weekends via the Resources page.

Do I need admin rights to change the Enterprise Calendar?

Yes, modifying or creating Enterprise Calendars requires Project Web App administrator permissions. If you do not have these permissions, you will need to contact your organization's PWA administrator to make the changes.
