區分一天中的工作時間和非工作時間需要一個日配置文件，該日配置文件可以指定精確的時鐘時間，例如從8.00 h到12.00 h am和從1.00 h到5.00 h pm。由于新創建的日配置文件僅包含工作時間，因此任何中斷都應定義為非工作間隔。
示例代碼C＃
// Defining a day profile
VcCalenderProfile calendarProfile =
calendar.CalendarProfileCollection.Add("DayProfile");
calendarProfile.Type = VcCalendarProfileType.vcDayProfile;
VcInterval interval =
calendarProfile.IntervalCollection.Add("Interval_1");
// 00:00-8:00
interval.CalendarProfileName = "";
interval.StartTime = new DateTime(2011, 1, 1, 0, 0, 0);
interval.EndTime = new DateTime(2011, 1, 1, 8, 0, 0);
interval = calendarProfile.IntervalCollection.Add("Interval_2");
// 12:00-13:00
interval.CalendarProfileName = "";
interval.StartTime = new DateTime(2011, 1, 1, 12, 0, 0);
interval.EndTime = new DateTime(2011, 1, 1, 13, 0, 0);
interval = calendarProfile.IntervalCollection.Add("Interval_3");
// 17:00-24:00
interval.CalendarProfileName = "";
interval.StartTime = new DateTime(2011, 1, 1, 17, 0, 0);
interval.EndTime = new DateTime(2011, 1, 1, 0, 0, 0);示例代碼VB.NET
' Defining a day profile
Dim calendarProfile As VcCalenderProfile =
calendar.CalendarProfileCollection.Add("DayProfile")
calendarProfile.Type = VcCalendarProfileType.vcDayProfile
Dim interval As VcInterval =
calendarProfile.IntervalCollection.Add("Interval_1")
' 00:00-8:00
interval.CalendarProfileName = ""
interval.StartTime = New DateTime(2011, 1, 1, 0, 0, 0)
interval.EndTime = New DateTime(2011, 1, 1, 8, 0, 0)
interval = calendarProfile.IntervalCollection.Add("Interval_2")
' 12:00-13:00
interval.CalendarProfileName = ""
interval.StartTime = New DateTime(2011, 1, 1, 12, 0, 0)
interval.EndTime = New DateTime(2011, 1, 1, 13, 0, 0)
interval = calendarProfile.IntervalCollection.Add("Interval_3")
' 17:00-24:00
interval.CalendarProfileName = ""
interval.StartTime = New DateTime(2011, 1, 1, 17, 0, 0)
interval.EndTime = New DateTime(2011, 1, 1, 0, 0, 0)時鐘時間由對象DateTime設置。日期部分被忽略，因為在這種情況下它毫無意義。只需要在構造函數中設置日期，即可為構造函數所需的所有參數設置一個值。在Interval_3中，指定0h或24h是很重要的，因為后者在DateTime對象中不被接受。
一年中的定期日期（例如1月1日的除夕夜或12月25日和26日的圣誕節和節禮日），由涵蓋全年的日歷配置文件定義。
示例代碼C＃
// Setting a profile of fixed annual holidays
VcCalenderProfile calendarProfile =
calendar.CalendarProfileCollection.Add("YearProfile");
calendarProfile.Type = VcCalendarProfileType.vcYearProfile;
VcInterval interval = calendarProfile.IntervalCollection.Add("New
Year");
interval.CalendarProfileName = "";
interval.DayInStartMonth = 1 ;
interval.StartMonth = VcMonth.vcJanuary;
interval.DayInEndMonth = 1;
interval.EndMonth = VcMonth.vcJanuary;
SetAppearanceForHolidays(interval);
interval = calendarProfile.IntervalCollection.Add("Chrismas");
interval.CalendarProfileName = "";
interval.DayInStartMonth = 25 ;
interval.StartMonth = VcMonth.vcDecember;
interval.DayInEndMonth = 26;
interval.EndMonth = VcMonth.vcDecember;
SetAppearanceForHolidays(interval);示例代碼VB.NET
' Setting a profile of fixed annual holidays
Dim calendarProfile As VcCalenderProfile =
calendar.CalendarProfileCollection.Add("YearProfile")
calendarProfile.Type = VcCalendarProfileType.vcYearProfile
Dim interval As VcInterval = calendarProfile.IntervalCollection.Add("New
Year")
interval.CalendarProfileName = ""
interval.DayInStartMonth = 1
interval.StartMonth = VcMonth.vcJanuary
interval.DayInEndMonth = 1
interval.EndMonth = VcMonth.vcJanuary
SetAppearanceForHolidays(interval)
interval = calendarProfile.IntervalCollection.Add("Christmas")
interval.CalendarProfileName = ""
interval.DayInStartMonth = 25
interval.StartMonth = VcMonth.vcDecember
interval.DayInEndMonth = 26
interval.EndMonth = VcMonth.vcDecember
SetAppearanceForHolidays(interval)為了避免重復設置產生相同的假期外觀，我們使用名為SetAppearanceForHolidays的方法收集調用：
示例代碼C＃
// Method to set the visual appearance of holidays
void SetAppearanceForHolidays(VcInterval interval)
{
interval.BackgroundColor = Color.FromArgb(255, 255, 164, 164);
interval.Pattern = VcFillPattern.vcWeavePattern;
interval.PatternColor = Color.FromArgb(255, 64, 64, 64);
interval.LineColor = Color.FromArgb(255, 128, 128, 128);
interval.LineThickness = 1;
interval.LineType = VcLineType.vcSolid;
interval.UseGraphicalAttributes = true;
}示例代碼VB.NET
' Method to set the visual appearance of holidays
Private Sub SetAppearanceForHolidays(ByVal interval As VcInterval)
interval.BackgroundColor = Color.FromArgb(255, 255, 164, 164)
interval.Pattern = VcFillPattern.vcWeavePattern
interval.PatternColor = Color.FromArgb(255, 64, 64, 64)
interval.LineColor = Color.FromArgb(255, 128, 128, 128)
interval.LineThickness = 1
interval.LineType = VcLineType.vcSolid
interval.UseGraphicalAttributes = True
End Sub
請注意：顏色屬性僅在其CalendarProfileName設置為<WORK>或<NONWORK>的間隔內有效。另外，間隔屬性UseGraphicalAttribute需要設置為true。對于calenderGrid屬性UseGraphicalAttributesOfIntervals同樣如此。
每年必須計算浮動假期（例如復活節）和其他依賴于它們的假期，并且需要將其作為固定日期分配給日歷。下面的方法對此非常有用：
示例代碼C＃
// Method to find floating holidays
public enum Anniversary
{
AshWednesday,
GoodFriday,
EasterSunday,
EasterMonday,
FeastOfCorpusChristi,
AscensionOfChrist,
WhitSunday,
WhitMonday,
CentralEuropeanSummerTimeStart,
CentralEuropeanSummerTimeEnd
}
private DateTime calculateAnniversaryForYear(int year, Anniversary
specialDay)
{
int g = year % 19;
int c = year / 100;
int h = (c - c / 4 - (8 * c + 13) / 25 + 19 * g + 15) % 30;
int i = h - (h / 28) * (1 - (29 / (h + 1)) * ((21 - g) / 11));
int j = (year + year / 4 + i + 2 - c + c / 4) % 7;
int month = 3 + (i - j + 40) / 44;
int day = i - j + 28 - 31 * (month / 4);
int dayOffset = 0;
switch (specialDay)
{
case Anniversary.AshWednesday:
dayOffset = -40;
break;
case Anniversary.GoodFriday:
dayOffset = -2;
break;
case Anniversary.EasterSunday:
break;
case Anniversary.EasterMonday:
dayOffset = 1;
break;
case Anniversary.AscensionOfChrist:
dayOffset = 39;
break;
case Anniversary.WhitSunday:
dayOffset = 49;
break;
case Anniversary.WhitMonday:
dayOffset = 50;
break;
case Anniversary.FeastOfCorpusChristi:
dayOffset = 60;
break;
case Anniversary.CentralEuropeanSummerTimeStart:
month = 3;
day = 31 - Convert.ToInt32(new DateTime(year, 3,
31).DayOfWeek);
break;
case Anniversary.CentralEuropeanSummerTimeEnd:
month = 10;
day = 31 - Convert.ToInt32(new DateTime(year, 10,
31).DayOfWeek);
break;
}
return new DateTime(year, month, day).AddDays(dayOffset);
}示例代碼VB.NET
' Method to find floating holidays
Public Enum Anniversary
AshWednesday

End Enum
Private Function calculateAnniversaryForYear(ByVal year As Integer,
ByVal specialDay As Anniversary) As DateTime
Dim g As Integer = Decimal.Remainder( year , 19 )
Dim c As Integer = year / 100
Dim h As Integer = (c - c / 4 -(8 * c + 13) / 25 + 19 * g + 15) % 30
Dim i As Integer = h -(h / 28) *(1 -(29 /(h + 1)) *((21 - g) / 11))
Dim j As Integer = (year + year / 4 + i + 2 - c + c / 4) % 7
Dim month As Integer = 3 +(i - j + 40) / 44
Dim day As Integer = i - j + 28 - 31 *(month / 4)
Dim dayOffset As Integer = 0
Select Case specialDay
Case Anniversary.AshWednesday
dayOffset = -40
Case Anniversary.GoodFriday
dayOffset = -2
Case Anniversary.EasterSunday
Exit Function
Case Anniversary.EasterMonday
dayOffset = 1
Case Anniversary.AscensionOfChrist
dayOffset = 39
Case Anniversary.WhitSunday
dayOffset = 49
Case Anniversary.WhitMonday
dayOffset = 50
Case Anniversary.FeastOfCorpusChristi
dayOffset = 60
Case Anniversary.CentralEuropeanSummerTimeStart
month = 3
day = 31 - Convert.ToInt32(New DateTime(year, 3, 31).DayOfWeek)
Case Anniversary.CentralEuropeanSummerTimeEnd
month = 10
day = 31 - Convert.ToInt32(New DateTime(year, 10,
31).DayOfWeek)
End Select
Return New DateTime(year, month, day).AddDays(dayOffset)
End Function
在下一步中，將周配置文件和假日配置文件作為間隔分配給日歷。然后以相同的方式計算浮動假期并將其分配給日歷：
示例代碼C＃
// Assembling the week profile, the holiday profile and the floating
holidays into an interval
interval = calendar.IntervalCollection.Add("Weekly_Pattern");
interval.CalendarProfileName = "WeekProfile";
interval = calendar.IntervalCollection.Add("Yearly_Pattern");
interval.CalendarProfileName = "YearProfile";
int startYear = vcGantt1.TimeScaleStart.Year;
int endYear = vcGantt1.TimeScaleEnd.Year;
for (int i=startYear; i<=endYear; i++)
{
interval = calendar.IntervalCollection.Add("GoodFriday_" +
i.ToString());
interval.CalendarProfileName = "";
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.GoodFriday);
interval.EndDateTime = interval.StartDateTime;
SetAppearanceForHolidays(interval);
interval = calendar.IntervalCollection.Add("EasterMonday_" +
i.ToString());
interval.CalendarProfileName = "";
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.EasterMonday);
interval.EndDateTime = interval.StartDateTime;
SetAppearanceForHolidays(interval);
interval = calendar.IntervalCollection.Add("FeastOfCorpusChristi_" +
i.ToString());
interval.CalendarProfileName = "";
interval.StartDateTime = calculateAnniversaryForYear
(i, Anniversary.FeastOfCorpusChristi);
interval.EndDateTime = interval.StartDateTime;
SetAppearanceForHolidays(interval);
interval = calendar.IntervalCollection.Add("AscensionOfChrist_" +
i.ToString());
interval.CalendarProfileName = "";
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.AscensionOfChrist);
interval.EndDateTime = interval.StartDateTime;
SetAppearanceForHolidays(interval);
interval = calendar.IntervalCollection.Add("WhitMonday_" +
i.ToString());
interval.CalendarProfileName = "";
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.WhitMonday);
interval.EndDateTime = interval.StartDateTime;
SetAppearanceForHolidays(interval);
}
vcGantt1.CalendarCollection.Update();示例代碼VB.NET
' Assembling the week profile, the holiday profile and the floating
holidays into an interval
interval = calendar.IntervalCollection.Add("Weekly_Pattern")
interval.CalendarProfileName = "WeekProfile"
interval = calendar.IntervalCollection.Add("Yearly_Pattern")
interval.CalendarProfileName = "YearProfile"
Dim startYear As Integer = vcGantt1.TimeScaleStart.Year
Dim endYear As Integer = vcGantt1.TimeScaleEnd.Year
Dim i As Integer
For i = startYear To endYear Step i + 1
interval = calendar.IntervalCollection.Add("GoodFriday_" +
i.ToString())
interval.CalendarProfileName = ""
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.GoodFriday)
interval.EndDateTime = interval.StartDateTime
SetAppearanceForHolidays(interval)
interval = calendar.IntervalCollection.Add("EasterMonday_" +
i.ToString())
interval.CalendarProfileName = ""
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.EasterMonday)
interval.EndDateTime = interval.StartDateTime
SetAppearanceForHolidays(interval)
interval = calendar.IntervalCollection.Add("FeastOfCorpusChristi_" +
i.ToString())
interval.CalendarProfileName = ""
interval.StartDateTime = calculateAnniversaryForYear
(i, Anniversary.FeastOfCorpusChristi)
interval.EndDateTime = interval.StartDateTime
SetAppearanceForHolidays(interval)
interval = calendar.IntervalCollection.Add("AscensionOfChrist_" +
i.ToString())
interval.CalendarProfileName = ""
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.AscensionOfChrist)
interval.EndDateTime = interval.StartDateTime
SetAppearanceForHolidays(interval)
interval = calendar.IntervalCollection.Add("WhitMonday_" +
i.ToString())
interval.CalendarProfileName = ""
interval.StartDateTime = calculateAnniversaryForYear(i,
Anniversary.WhitMonday)
interval.EndDateTime = interval.StartDateTime
SetAppearanceForHolidays(interval)
Next
vcGantt1.CalendarCollection.Update()
這些是組裝日歷所需的摘要步驟。根據要求，可以省略單個步驟：
1、創建不同工作日的日配置文件
2、通過使用日配置文件組裝周配置文件
3、定義假期資料
4、將周配置文件和假日配置文件分配給日歷的間隔集合
5、為間隔集合分配其他日期（例如浮動假期）
間隔對象允許定義可解釋為工作時間或非工作時間的時間段。通過CalendarProfileName屬性將句點區分為<WORK>或<NONWORK>。通過此屬性，日歷還可以引用其他現有配置文件并采用其設置。設置此屬性時，請注意，根據間隔類型，只能分配某些配置文件類型。間隔類型由選定的配置文件類型隱式選擇。日歷配置文件的預設默認值vcDayProfile可以在初始時（即在定義間隔之前）通過相應的設置進行修改。
配置文件類型建議允許的間隔類型。例如，日期配置文件始終需要vcDayProfileInterval類型的間隔。
日歷配置文件可以顯示類型為日配置文件、周配置文件、年配置文件和變量配置文件。在一天配置文件中，只能通過在一天的限制范圍內的時鐘時間來定義間隔。一周配置文件包含要在某些天應用的日期配置文件。年份配置文件分配選定的一天配置文件，這些配置文件適用于單個重復日期或幾個重復日期。變量配置文件包含一系列不同的工作時間。根據間隔類型vcCalendarInterval、vcDayProfileInterval、vcWeekProfileInterval、vcYearProfileInterval和vcVariableProfileInterval，僅對象的某些屬性是相關的。下表映射了概要文件類型和相關屬性。
CalendarInterval在精確定義的間隔中描述了唯一的時間跨度。例：2010年5月5日從11:30時到2010年9月15日17:00時。
YearProfileInterval允許定義每年重復一次的天數或時間跨度。例：5月1日或12月24日至26日。
WeekProfileInterval處理一周中的一天或幾天。例：星期六或星期一至星期五。
DayProfileInterval處理一天之內的時間規格。例：8.00時至17.00時。
VariableProfile描述了時間跨度，而不引用定義的日期或時間。時間間隔的單位可以是天、小時、分鐘或秒，并且由時間間隔對象的屬性TimeUnit指定。示例：4小時。
