Shows how to use Calendar.GetIntersectionCalendar() method to perform calculation on assignment’s calendar.

var project = new Project(DataDir + "CalculateWorkHours.mpp");

foreach (var ra in project.ResourceAssignments)
{
    if (ra.Resource == null)
    {
        continue;
    }

    ICalendar assignmentCalendar;

    Calendar taskCalendar = ra.Task.Calendar != null && !ra.Task.Duration.IsEstimated ? ra.Task.Calendar : null;
    Calendar resourceCalendar = ra.Resource.Calendar != null && !ra.Task.IgnoreResourceCalendar
        ? ra.Resource.Calendar
        : null;

    if (taskCalendar != null && resourceCalendar != null && !ReferenceEquals(taskCalendar, resourceCalendar))
    {
        assignmentCalendar = Calendar.GetIntersectionCalendar(taskCalendar, resourceCalendar);
    }
    else
    {
        assignmentCalendar = taskCalendar ?? resourceCalendar;
    }

    if (assignmentCalendar == null)
    {
        assignmentCalendar = project.Calendar;
    }

    var workingHours = assignmentCalendar.GetWorkingHours(ra.Start, ra.Finish);

    Console.WriteLine("Working hours for assignment '{0}' : {1}", ra, workingHours);

    var date = new DateTime(2025, 4, 7);
    Console.WriteLine("Working times for date '{0}':", date);

    foreach (var wt in assignmentCalendar.GetWorkingTimes(date))
    {
