I am trying to find the difference between two dates. The first of the two dates can be changed and when it is changed, the difference between the original dates has to be retained. This means that I have to automatically change the second date to have the same difference in days as it did before, but with a new first date. [code]I have the value of the old date1(currDate) and the new date1 value(newDate). I need to get the difference between these, and then add or minus these days from the endDate.
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 try use datediff function to get month interval between 2 hijri dates but the function deals with the dates as Gregorian Dates so the result is not correct.
I'm trying to make this program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date. This is the layout I've created so far, the two date boxes currently show the system date so even if I change the system date, both those boxes will adjust to show it as well. I want to try and make the system date a box without a drop down arrow and so you cannot edit the box at all. The box below is fine how it is as the user can enter any date they desire. And the text box at the bottom needs to show the difference between the system date and the inputted date.
I'm using datediff to establish difference between two dates using datetimepicker.i.m nnot getting the right results. a one day difference returns a 0, a two day difference returns a 1 etc. the code I am using is posted below.

In 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.
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.

I'm using two datetimepicker controls to set the start and end dates for a range of dates I'm searching for.I want to make sure that the start date selected is not greater than the end date.
