How to create simple calendar from scratch.

```cpp
[C#]
// create empty calendar
Calendar calendar = new Calendar("New calendar");
// adds default working days (8 working hours from 9:00 to 17:00)
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Monday));
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Tuesday));
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Wednesday));
// create new new working day
WeekDay myWeekDay = new WeekDay(DayType.Thursday);
// Sets working time. Only time part of DateTime is important
    WorkingTime wt1 = new WorkingTime();
    wt1.FromTime = new DateTime(1, 1, 1, 6, 0, 0, 0);
    wt1.ToTime = new DateTime(1, 1, 1, 12, 0, 0, 0);
    WorkingTime wt2 = new WorkingTime();
    wt2.FromTime = new DateTime(1, 1, 1, 14, 0, 0, 0);
    wt2.ToTime = new DateTime(1, 1, 1, 18, 0, 0, 0);
    myWeekDay.WorkingTimes.Add(wt1);
    myWeekDay.WorkingTimes.Add(wt2);
    myWeekDay.DayWorking = true;
calendar.Days.Add(myWeekDay);
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Friday));
// adds weekend
calendar.Days.Add(new WeekDay(DayType.Saturday));
calendar.Days.Add(new WeekDay(DayType.Sunday));
```

```cpp
[VB]
' create empty calendar
Dim calendar As Calendar =  New Calendar("New calendar")
' adds default working days (8 working hours from 9:00 to 17:00)
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Monday))
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Tuesday))
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Wednesday))
' create new new working day
Dim myWeekDay As WeekDay =  New WeekDay(DayType.Thursday)
' Sets working time. Only time part of DateTime is important
    Dim wt1 As WorkingTime =  New WorkingTime()
    wt1.FromTime = New DateTime(1, 1, 1, 6, 0, 0, 0)
    wt1.ToTime = New DateTime(1, 1, 1, 12, 0, 0, 0)
    Dim wt2 As WorkingTime =  New WorkingTime()
    wt2.FromTime = New DateTime(1, 1, 1, 14, 0, 0, 0)
    wt2.ToTime = New DateTime(1, 1, 1, 18, 0, 0, 0)
    myWeekDay.WorkingTimes.Add(wt1)
    myWeekDay.WorkingTimes.Add(wt2)
    myWeekDay.DayWorking = True
calendar.Days.Add(myWeekDay)
calendar.Days.Add(WeekDay.CreateDefaultWorkingDay(DayType.Friday))
' adds weekend
calendar.Days.Add(New WeekDay(DayType.Saturday))
calendar.Days.Add(New WeekDay(DayType.Sunday))
```

Calendars are used to define standard working and non-working times. Projects must have one base calendar. Tasks and resources can have their own non-base calendars that are based on a base calendar.
