Okay writing on an event script via razor and inserting it via macro.

First here's the code for calculating the days etc.

@{
DateTime firstDay = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
int daysInCurrentMonth = DateTime.DaysInMonth(firstDay.Year, firstDay.Month);
DateTime lastDay = new DateTime(Model.yearToShow, Model.monthToShow, daysInCurrentMonth);
// Sunday casted to int gives 0 but that will not work for us, we need 7 to be able to calculate number of empty cells correctly
int dayOfWeekFirst = ((int)firstDay.DayOfWeek > 0) ? (int)firstDay.DayOfWeek : 7;
int dayOfWeekLast = ((int)lastDay.DayOfWeek > 0) ? (int)lastDay.DayOfWeek : 7;
}

But throws this error:

Error loading Razor Script calendar.cshtml
The best overloaded method match for 'System.DateTime.DateTime(long, System.DateTimeKind, bool)' has some invalid arguments

Checked this out in Visual Studio, everything is okay. Could it be that there is a problem with referencing or assembly?

Thanks for every input

Hi,

you're mixing DateTime.Now and monthToShow, so might be more days than allowed in that particular month, shouldn't the first line be :
```
DateTimefirstDay =newDateTime(Model.yearToShow,Model.monthToShow,1); 
```

Sorry for my stupidity, got it working now:

@using umbraco.MacroEngines
@using System.Web

@{
DateTime firstDay = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
int daysInCurrentMonth = DateTime.DaysInMonth(firstDay.Year, firstDay.Month);
int yearToShow = DateTime.Now.Year;
int monthToShow = DateTime.Now.Month;
DateTime lastDay = new DateTime(yearToShow, monthToShow, daysInCurrentMonth);
int dayOfWeekFirst = ((int)firstDay.DayOfWeek > 0) ? (int)firstDay.DayOfWeek : 7;
int dayOfWeekLast = ((int)lastDay.DayOfWeek > 0) ? (int)lastDay.DayOfWeek : 7;
}

<table id="reservationCalendar">
  <thead>
  <tr>
  <td>
  <<
  </td>
  <td colspan="5">
  @firstDay.Year
  </td>
  <td>
  >>
  </td>
  </tr>
  </thead>
  <tr>
  <td>
  Mon
  </td>
  <td>

  <td>

  <td>

  </tr>
<tr>
  
  @for (int a = 1; a < dayOfWeekFirst; a++)
  {
  @:<td></td>
  }
  
  @for (int i = 1; i <= daysInCurrentMonth; i++)
  {
  DateTime renderedDay = new DateTime(firstDay.Year, firstDay.Month, i);

  // if Sunday
  if (renderedDay.DayOfWeek == DayOfWeek.Sunday)
  {
  @:<td class="calendar-holiday">@i</td></tr><tr>
  }
  // if Saturday
  else if (renderedDay.DayOfWeek == DayOfWeek.Saturday)
  {
  @:<td class="calendar-holiday">@i</td>
  }
  // if normal day
  else
  {
  @:<td>@i</td>
  }
  }
  
  @for (int a = 1; a <= 7-dayOfWeekLast; a++)
  {
  @:<td></td>
  }
  </tr>
</table>
