Calculate Working Time Between Dates In Access
Oct 26, 2006
I have searched the forum for this answer but no luck. :(
I'm trying to calculate the amount of WORKING time between two dates in an Access database. At the moment i am just subtracting one date from another but this gives me all of the time in between including weekends and evenings.
I need this time to be calculated in hours.
In Excel i know there is a NETWORKINGDAYS function which does something similar but with days rather than hours.
At least if i could get the working days i could then convert it into hours.
Please help!

The below function returns correct time difference between workdays. However, it is excluding Saturday as per the code.
It is calculating 06:30 am to 22:00 pm time for weekdays but I also want it to calculate the time from 10:00 to 13:30 on a Saturday.
I am trying to use the NetworkMinutes function to achieve this. However, there is a problem getting the time for Saturday.
Code:
Option Compare Database
Option Explicit
'---------------------------------------------------------------------------------------
' Procedure : NetWorkMinutes
' Author : Rod
' Date : 13/12/2012
' Purpose : Returns the number of work minutes between two date-time arguments.
[code]...

We are collecting data from client files that have multiple dates (start_date, event1_date, event2_date, end_date.) For client protection purposes, we are absolutely not allowed to leave the facility with the actual dates. However, we want to know how many days have passed between each event. I thought about having the data collectors enter each date, have a calculated field store the time between dates, and then have the actual dates cleared when the record is saved or when the person moves to the next record.

I hope you can help. I have a database and I am trying to work out the working days between the start date and the end date of a programme. This will not take into account any weekends or bank holidays. I have created a separate table called tblHolidays which has a list of the Bank Holidays. The majority of it works but out of 1700 records 50 don’t. These are ones in which it starts on 1 month finished on another or has a bank holiday. It works with certain bank holidays but not all of them. Bank holidays go back to the beginning of 2006
The following is the code I have used:
Public Function WorkingDays2(Start_Date As Date, End_Date As Date) As Integer
On Error GoTo Err_WorkingDays2
Dim intCount As Integer
Dim rst As DAO.Recordset
Dim DB As DAO.Database
Set DB = CurrentDb
Set rst = DB.OpenRecordset("SELECT [HolidayDate] FROM tblHolidays", dbOpenSnapshot)
Start_Date = Start_Date + 1
intCount = 0
Do While Start_Date <= End_Date
rst.FindFirst "[HolidayDate] = #" & Start_Date & "#"
If Weekday(Start_Date) <> vbSunday And Weekday(Start_Date) <> vbSaturday Then
If rst.NoMatch Then intCount = intCount + 1
End If
Start_Date = Start_Date + 1
Loop
WorkingDays2 = intCount
Exit_WorkingDays2:
Exit Function
Err_WorkingDays2:
Select Case Err
Case Else
MsgBox Err.Description
Resume Exit_WorkingDays2
End Select
End Function
I then used the SQL
Select WorkingDays2 ([start_Date], [End_Date]) As CountDays
This is driving me crazy!!:mad:

I have a program that runs under access 2007 that I use at my work. We will soon be updating to MS office 2010 and the program will not work now because a calender file .ocx was removed from access 2010. Is there a way to get the 2007 .ocx file to work in access 2010?The program I am using is a relatively simple stand-alone and unsupported app that we use to request patient arrival and departure from various radiology tests inside a hospital. No reports are made from the app other than the number of patient transports for the day.
The app is placed on a common drive accessed from any pc in the hospital. No special permissions are required. But our app does use the calendar, time and date functions in access 2007. When I tried the app on a pc with access 2010, it basically says it (access) cannot open the app because a .ocx file is not present.Is there a way to make the access 2010 calendar file work in access 2007?

Input:
Table with the following details:

Table same as input but with a column that shows for each record the Due Date. The due date would be calculated by adding payment terms in days from another table to the Invoice date.

I have a database that I need to calculate a query that is based on 3 dates. For example...I have an admission date and a discharge date in my database.
If there is no date in the discharge date then I need it to calculate the number of days between the admission date and "today's date." If there is a discharge date then I need to calculate the difference between admission date and discharge date.
Basically i need a length of stay figure. I can figure the formula in excel but cannot get it to work in access. Here is my formula in excel
=If(ISBLANK(DischargeDate),Sum(today()),sum(Discha rgeDate-AdmissionDate)

I need to calculate the passed working days and show them in a form. I should be also able to use the number in a query later on. in excel I use the formula to get the days passed:
Code:
=IF(ISERROR(MATCH(F10,Dictionary!C:C,0)),NETWORKDAYS(D10, TODAY(), Dictionary!$E$2:$E$43),"Status Excluded")
D = "Date_uploaded" in access table "tbl_All_Cases"
F = "Status_Case" in access table "tbl_All_Cases"
c:c = dictionary case status
E:E = dictionary holidays
"Status Excluded" will show up in the cell if a case has one of the status from the dictionary..I created a table: tbl_Dictionary where there are 2 fields: "Case_Status" and "Holidays".How can I translate the above formula into something that access will understand?

I am woking on a project full of nightmares. My latest, and the one I am currently unable to solve, involves trying to calculate the number of days between Billing Dates.
I have a table named "Date" - I didn't design this!
It contains a field named "Date"
If I query for just that Field I get the following:
Date
9/8/2005
8/8/2005
7/8/2005
6/8/2005
5/9/2005
...
I need to figure out a way to determine the number of days between the bills so I can calculate the average cost per day.
It seems like it should be an easy thing using like the datediff function or something, but since they are in separate records (rows), I can't figure it out. I have tried and tried and tried.
Any suggestions would be VERY much appreciated.

I have a database with 10-12 fields containing dates certain things were completed. There is also a field for the 3 different locations we have and a program year 2006, 2007, or 2008. What they would like to do is click a button and get a list to choose the first date they which to compare, then a list to choose the second date, calculate the number of days between the two dates, select the program year from a list, and a location from a list. Can anyone help me with how to do this if it's possible?
The fields look something like this:
Prog Year Location DateA Date B DateC DateE
2006 G date date date date
2006 G date date date date
2006 P date date date date
2008 D date date date date
2007 P date date date date
For Example, I might want 2006 Program Year, Location P, calculating days between DateA and DateB, except that the next time I might want to choose a different set of criteria.
Any ideas?
THANK YOU!

Hello,
Was wondering if it is possible to create a query or another method that would calculate future dates based on inputted info ?
For example a person inputs on a form a date completed (06/14/07) and then also selects a frequency of when this has to be revisited....monthly, quarterly, semi-annually.
So based on the date completed that the person inputs I'm trying to get the date if they select monthly of 7/14/07 (using above date example).
Any help would be greatly appreciated.
Thank you

My database includes two separate dates related to a vehicle purchase and default payments resulting in repossession. I need to find out how many weeks passed between those dates.
Example:
03/14/12 Date of automobile purchase
06/06/13 Date of last payment before default
How many weeks in between? And then I need to average all of those figures so my company can see the usual week-term time frame that our customers are defaulting and getting repossessed.

What I have is two fields, one is a simple date and the other is slightly more complex as it holds a date but in a different structure (a dated case number).
The case numbers are for example, 150211551223 the date being the first 6 numbers and equaling to 11/02/2015. so the code will need to grab this data, spin it around and convert it.
The formula will then be:
simpledate - convertedcasenumberdate = days between.
(simpledate will always be the latest date of the two).

Hello,
I am trying to create a listbox that shows "calculated" dates for a two week payroll. I have a field in a table that is set to a start date (05.31.05) and another field that specifies the number of days between dates (14). I would like set a listboxes recordsource to show the start date and then calculate the next 4 dates using the first date (05.31.05) and the range (14) without actually storing any dates in the table. I can figure out how to do it if the values are stored, but I just want to know if this is possible to get the results another way.This may sound crazy and unecessary, but I want to know if this is possible without storing values in the table.
Listbox values:
05.31.05 - (first date from table)
06.14.05 - (first date + 14)
06.28.05 - (first date + 2*14)
07.12.05 - (first date + 3*14)
07.18.05 - (first date + 4*14)
Is this possible? HTMS. Thanks.
