Adding Business Days To Start Date Including Holidays
Aug 5, 2012
I read that .Net has no function equivalent to Excel's "Workdays" function, which adds a specified number of workdays to a startdate, including an array of holidays. I managed to find a function that adds the number of workdays to the startdate, but I am having no luck telling the function to add a day to the start date for each holiday within the date range. I've pasted a self-contained function below. Every time I compare the result against the Excel result, it's not adding up.
Private Function CalcEndWD_5wkd(StartDate As Date, WD As Integer) As Date
Dim Holidays(23) As Date
Holidays(0) = #10/5/2012#
Holidays(1) = #11/12/2012#
Holidays(2) = #11/21/2012#
[Code] .....
I need to calculate the end date given the number of business days (excluding weekend and holidays). All the examples I've seen so far return the number of business days between a start date and an end date.
Is there a method or function that I can use to get the number of days between a start date and end date? I tried using Timespan, but I was noyt able to convert the value to a string. What I am doing is I have 3 text boxes. 1 with start date value user will set using a calendar. And another with end date set using a calendar.And the 3rd text box is being used to display that difference between the two dates.
I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)
I am writing a program that takes a shipdate and generates a timeline of deadlines for a manufacturing job by working backwards from the shipdate. I hav no problem handling weekends. However, some holidays are giving me problems. For holidays that don't have a set date (Thanksgiving, Labor Day, Memorial Day...) what is the best way to determine the date they fall on? Most of the examples I have seen use an array of dates (either from a file or hard coded) for these holidays. Is there a way to do this tha won't require someon to generate a list every year for these holidays?
below i have a piece of code, i have to calculate the next working day +5 from today but this calculation has to calculate days from monday to friday and exclude weekends(saturday & sunday) and also excluse public holidays.i have tried but what i got is that it calculates 5days without excluding anything.example if a record is taken out monday, the return date must be the next monday but with this code calculates weekends as well it says return date is saturday.
Public Function AddWorkingDays(ByVal DateIn As DateTime, _ ByVal ShiftDate As Integer) As DateTime ' Adds the [ShiftDate] number of working days to DateIn
I know the datediff function can give the count of the number of days between two different dates, but how can I get the count of the number of business days - i.e. Monday - Friday - between two dates?
Lets say i had a label with 9/6/2010 11:59:99 that was selected from the month calendar control, is there anyway to determine how many days are from the present days date to the selected end date?
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.
I am traying to use the DateTimePicker to extract days diff from a date selected on DateTimePicker1 to a date selected on DateTimePicker2. I have no problem substracting the daydiff in numbers of days. The problem I have is that I need the DateTimePicker to tell me how many of those days are weekends (friday, saturday) and how many are weekdays.
using an object-binding I have a an object representing "Employee". The employee has an ID-property. The ID of the employee must be unique.
My validation of the entered data is handled in the property set part of the object. In general, I validate criteria belonging to the object to validate only (eg numeric range of the ID, if it's value is not empy, ...). But in this case I need to know all ID's from the other employees. My tried this:
I have a DateTimePicker (dtBBDate) and a textbox(txtDBBDate) object in my form....but what i want when user change the date of dtBBDate my text box should show show the date 10 days minus from that selected date i.e. if user select 10 may text box should show me 1st may?
all you clever people out there I'm rather new to this and I'm using vb.net in visual studio 2005 and I want to add 20 WORKING days to the TODAY() value. I'm able to add the days, but it also adds NON-WORKING days.
I have a datagridview named DGVAttend which has 21 columns, including a date col. It takes data from more than 100 text files. Only those files are processed which has relevant data and within it only relevant data are copied and not the full file.
Dim NoOfRelevantFiles As Integer Dim RelevantFileNames As System.Collections.ObjectModel.ReadOnlyCollection(Of String) = My.Computer.FileSystem.FindInFiles(frmTxtFileDetails.txtboxFolder.Text, "Daily
I want to be able to add a folder (and inturn, all of it's contents including subfolders) to a setup project. I can manually add a folder, then manually add all of the files for that folder; but this is a NetHelp folder with lots of subfolders and files.
Is there a way to tell the setup to add everything in a folder to the setup files to be distributed??
I just wanna know what is the way of tracking the record of employee when i save theyre info in payroll. Like if the employee got paid in these date lets just say he will get paid every 15 days of his work not including sat and sunday. If i save the info the error will say."You have been paid on this day / week" .All i got is save the info but when it comes to checking i cant do it
I have a datatable that stores information on employees. What i'm trying to do is use it to run a seniority list looping through the table using the current system date. The looping part i have no problem with, and the system date calculation also i know how to do. The problem call the date from the startDate column to do the calculation.
i have tried
dim sDate As date = "startdate"
but i get an error that it cannot be converted to date.
I have to display all days base on a date range. For example my date range is "January 1, 2011" to "February 28, 2011". Now what i want is to display all the dates base on that range, what i meant about "display the dates" is like this.
on my design i have a listbox, datetimePicker and a button. how do i pick a date like for example 14 feb 2010 from the datetimePicker and click the button, then the listbox showing how many days from 1st jan 2010? should be 45days.
I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.

Have to find total days from two date controls after selecting dates in two controls it should print total days by calculating after immediate selection of second date control
How do you select records based on the next 10 days from todays date.For eg:Lets say I want to select records based on ReqDt = today + 10Select * from Sample1 where reqdt <= today + 10
