Calculate Number Of Months Between Two Dates?
Mar 3, 2011I have two date values.

Dim d1 As DateTime = New DateTime(2010, 6,6)
Dim d2 As DateTime = New DateTime(2011, 2,2)
I have two date values.
Example:
Dim d1 As DateTime = New DateTime(2010, 6,6)
Dim d2 As DateTime = New DateTime(2011, 2,2)
I am attempting to calculate the number of months between 2 dates in vb 2008. Effectively subtracting a date in the past from the current date and then manipulating it to the number of months between the two.
I have done this in VB 6 previously, but can't seem to do it in vb2008.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.
How to calculate the difference in months between two dates in C#? Is there is equivalent of VB's DateDiff() method in C#. I need to find difference in months between two dates that are years apart. The documentation says that I can use TimeSpan like:
[Code]...
but this gives me data in Days. I don't want to divide this number by 30 because not every month is 30 days and since the two operand values are quite apart from each other, I am afraid dividing by 30 might give me a wrong value.
I am searching an MS Access database via an asp written in VBscript. I am looking for entries that are less than 45 days old. The query worked great until October rolled around. Then none of the new entries were being displayed. I discovered that any month that has 2 digits, such as October with 10 or even Jan-Sept if I enter a "0" in the month (ie. 09 vs just 9), will not display. The SQL statement is below (created in Dream Weaver):
<%Dim rs_blog__MMColParamrs_blog__MMColParam = "entrydate"%>
<%Dim MinDateMinDate = DateAdd("d",-45,Date())%><%Dim rs_blogDim rs_blog_numRows
Set rs_blog = Server.CreateObject("ADODB.Recordset")rs_blog.ActiveConnection = MM_intranet_STRINGrs_blog.Source = "SELECT id, employee, subject, blog, entrydate FROM blog WHERE entrydate >= '" + Replace(MinDate, "'", "''") + "' ORDER BY id DESC"
How do I get the data that has 2 digits in the month to display and only show the entries that are no more than 45 days old.
I've been given two dates that takes their values from two respective dtpickers.I've got to calculate the exact amount of days, months and years between them.[code]The problem is that this function gives me ALL the amount of respective days, months and years passed, but I need to split them up in the correct way. Ex, between 28/2/98 and 13/1/2007 the result should be 15 days, 10 months and 8 years. And above all, the result is that the function indicates one month more (or one year more) with only one day (or month) passed between the two dates!

View 1 RepliesIn VB2005 I am trying to calculate the number of business days between two dates. I must also account for U.S. holidays (New Year's Day, Martin Luther King Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day/Friday after, Christmas Day). If a holiday falls on a Saturday, then the prior day (Friday) is assumed to be a holiday. Likewise, if the holiday falls on a Sunday then the following day (Monday) is assumed to be a holiday.
View 4 RepliesBefore I build my own and after looking for quite a while (to no avai) does any one know of a function that will return the dates of a recurrence.
For instance:
- The recurrence might be the first Monday of each month.
- The second week of each month.
So what I want is to pass the recurrence information to the function and it will return in an array all the dates that are applicable.I've looked at some other topics here but none are as comprehensive as what I need.
