Step-by-Step Guide
⚙️ Define Regular Working Days
Open the menu in the top left corner.
Go to Settings.
Select Work Schedule at the bottom.
By default, Monday to Friday are activated as working days.
This means:
Saturdays and Sundays are automatically skipped during scheduling.
These days appear greyed out in the calendar.
If your project regularly includes work on Saturdays, simply activate Saturday and save your settings.
📅 Add Non-Working Days (e.g. Public Holidays)
In addition to regular working days, you can define individual non-working days.
Click Add day and choose:
either a single day
or a date range (start and end date)
Save your entry afterward.
Example:
Good Friday to Easter Monday → these days will be highlighted in red in the calendar.
🗓 Display in the Lookahead plan
In the Lookahead plan, you can immediately see:
Non-activated working days → greyed out
Defined non-working days → highlighted in red
Scheduled tasks on non-working days → hatched display
This allows you to quickly check whether a day is generally non-working or has been intentionally scheduled.
➕ Schedule on a Non-Working Day
If work needs to take place on a Saturday or public holiday, you can still schedule tasks:
Click the plus icon on the desired day in the Lookahead plan and create the task as usual.
Or select a date range and intentionally include the non-working day.
This keeps your planning flexible—even for exceptions.
