Workday calendar
Overview
This is where the workday calendar - that is an indication of which dates are workdays and which dates are not - is maintained. The years available are controlled by the setting of the "Calendar from-to" in the adjoining Setup page.
This information is used when assigning process tasks Processes if the process in question is set up to calculate lead days based on a working day calendar as apposed to a normal 7-days-per-week calendar.
This allows automated deadlines (due dates) of process tasks that are based on recurring events +- lead/lag days to skip non workdays. Each process can be configured whether to take this calendar into account or not on the processes page.
