In Ms Project I'm able to define the number of working hours for a specific day (ie for day 16.01.2008 resource will work only 4 hours). I'm trying to do the same in Aspose.tasks but it only allow me to do this for all mondays, tuesdays, etc...
I've checked several posts where you define default hours per day (when you say day you mean Monday, Tuesday, etc...).
Can you please attach some source project file where you had set working hours for specific date in MS-Project, so I could read and check it in Aspose.Task?
CalendarHours used to define standard calendar days. If you need define special days you should use CalendarPeriods. You will find example on this page. It shows how to define additional non-working day but CalendarPeriod has also FromTime/ToTime properties.
