pass date to JSON feed

I am using the fullCalendar in a vb.net setting. I use a JSON feed contained within an aspx page to pass data to the calendar like this:

events: "JSONcalendarFeed.aspx"

I was wondering if there's a way to pass the currently selected month in fullCalendar to the page that generates the JSON feed so I can pull data for that month. Also whenever a year changed in the calendar, I'd need to pass in that new year.

Thanks!

PAGE

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="diaryFeed.aspx.vb" Inherits="ClubSites.diaryFeed" %>
<%  Response.Write(respondBack)%>

CODE BEHIND

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Request.QueryString.ToString <> "" Then
            'I don't understand why fullCalendar uses a Unix timestamp.. but use these queries if you use UNIX timestamp, common in PHP apparently

            If IsNothing(Request.QueryString("start")) Then
                _startDate = Date.Now.AddYears(-1)
                _endDate = Date.Now.AddYears(1)
            Else
                _startDate = CDateFromUNIX(Request.QueryString("start"))
                _endDate = CDateFromUNIX(Request.QueryString("end"))

            End If
            Try
                If Not Request.QueryString("Timestart").Length = 0 And Not Request.QueryString("TimeEnd").Length = 0 Then
                    _startDate = CDate(Request.QueryString("Timestart"))
                    _endDate = CDate(Request.QueryString("TimeEnd"))
                End If
            Catch ex As Exception

            End Try
            'End If

 respondBack = JsonConvert.SerializeObject([mycustom function that generates a data table], New Newtonsoft.Json.Converters.IsoDateTimeConverter())


end sub

I use json .net to convert my outgoing data to json so that diary can understand it

and a helper function to convert the Unix timestamps to .NET one

 Function CDateFromUNIX(ByVal timestamp As Double) As DateTime
        Dim origin As DateTime = New DateTime(1970, 1, 1, 0, 0, 0, 0)
        Return origin.AddSeconds(timestamp)
    End Function

I'm pretty sure that fullCalendar actually sends the start and end times to your page as parameters.

from events as jsonfeed the example says: /myfeed.php?start=1262332800&end=1265011200 So you should probably just read these two parameters and convert them from seconds (not ms in fullCalendar!) since January 1st 1970
