I am trying to calculate the difference in dates between two fields. How do I find the difference in days between field one which contains the date 04/12/2011 and field two which contains the date 04/12/2013? I have tried to use the datediff function, but it keeps telling me it doesn't recognize the field name, even though the spellings correct.
View 3 Replies View RelatedBasically, I am trying to calculate a integer number difference from two dates (TAT = Due-Date - Result_Date). The number is calculated and excludes weekends and ideally holidays (for that I have a tblHoliday but not sure how to use it). The function below seems to calculate a number but doesn't exclude weekends.
For example, if Due_Date is 9/26/2014 and Result_Date is 9/30/2014, then TAT is calculated to be 5 (should be 2).Since 9/26/2014 is a Friday only Friday and Monday are used in the calculation.
Code:
Option Compare Database
Public Function WorkingDays(StartDate As Date, EndDate As Date) As Long
Dim intCount As Long
intCount = 0

How can I calculate the difference between two dates but I only want to count the work days? So if was today and I wanted to go until 6/15/2015 the difference would be 5 and not 7 because I do not want to count Saturday or Sunday. Is there a special %datediff function where I would only count work days?
View 4 Replies View RelatedI have to create a query in access that will calculate two Date and time fields [Date & Time Left]/ [Date Returned], need to figure out between the two fields. Trying to identify when the rep returned the call and the number of business hours (6:00am - 4:30pm) it takes to return a message in Ms Access 2010.
The only issue is the calculation has to be done by time and so I have to calculate what time they left the message(so the difference between [Date & Time Left] and [Date Returned) [Date & Time Left] and when the rep returned the message which is suppose to be [Date Returned] but the problem with this field is the data entry is in date format (10/9/2014, 00/00/0000) of Date and not Date and Time like the [Date & Time Left] field, so I don't know what to do now. Not sure what to do now not a database that create or have allot of control over.
I have built a query to calculate the expiry dates of training courses but I am trying to input a criteria so that only dates within 90 days of todays date show. I am using Date()<90 but it doesn't return the correct information. What the criteria should be for this?

I have a list of client activity - client name, loan ID and loan date. I would like to create a new field that shows the number of days between one loan and the next. If I was doing it in excel, I would need to sort the data by client name and loan date and then calculate the number of days between the loan date of one loan and the loan date of the loan immediately prior to this.
View 14 Replies View RelatedI would like to create an Access Database that calculate due date based on 2 tables, one with invoices and supplier details. The other one with Supplier name et payment terms.
Input:
Table with the following details:
- Supplier Name

Output:
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 am using Access 2013.I am trying to create a query that will count the days difference between two dates. The dates are in the same field. I want to group by Region.So:
tblRegion = RegionID
tblStatus = StatusDate
I know how to use the DateDiff when it is two different fields, but I can't figure out how to do it from the same field.
I am wanting to get an expression that will return the difference in years and months between 2 dates. Specifically, I want to know peoples ages in years and months based on a person's D.O.B and todays date. I have managed to do it in years:

and in months but I would like to know how to return the difference in years and months.
I am designing mileage database in access 2010.
table:
1- maintbl (date, truckNo fillinQty,rate,cost, odometer, mileage)
Query:
1- mainquery (based on maintbl)
Form:
1- mainfrm (Based on mainquery)
i want to calculate mileage :
example:new odometer reading - previous odometer reading / filled in qty
example: 2000 km - 1000 km / 200 liters = 5 liters /km
Objective: How query will automatically calculate the difference of new odometer reading and last odometer reading for a specific truck number and divide it with filled in qty of fuel?
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.
I'm trying to calculate the number of days between two dates using the iif statement
Fields:
[LDW] "Last Day Worked"
[ReturnedDate]
DESCRIPTION: If ReturnedDate is null, then calculate the datediff "d" between LDW with Now(), if not, then calculate the datediff "d" between LDW with ReturnDate.
I tried this but it didn't work at all.
Days Absent: Iif(isnull([ReturnedDate],(DateDiff("d",[LDW],Now())),(DateDiff("d",[LDW],[ReturnedDate])))
I'm trying to build a query with an iif statement to calculate expiration dates within a query. For some reason what i'm trying to do is not working as expected.
Here's the situation. Every employees with an exception of two employees in the company has an expiration 2 years after the class took place. The two exceptions are the certified instructors who's training certification is good for three years.
I've created a query with the employeeid, training subject, and maxoftraining date.
I'm trying to write an if statement to give me the expiration date based on the above information. Here's what I have so far; however its not calculating based on the criteria.
Expiration: IIf([tblemployee]![EmpID]=1 Or 2,DateAdd("yyyy",3,[maxoftrainingdate]),DateAdd("yyyy",2,[maxoftrainingdate]))
At this point in time, all "expiration" dates are showing + 3 years rather than just the Employee ID's 1 and 2 and the rest +2 years.
Basically I have a report that shows any 'Issues' that wasnt closed within the KPI Target.
I have the report working, but I simply want to do a count of how many days the observations overran the 'Target Date of Closure'.
The report also shows observations that are not closed but passed their Target Date of Closure. These observations will not have a 'Actual Closure Date', but I would like to still have a count of how many days its overrun closure.
This is a formula I tried to piece together but obviously not correct as it's not returning anything;
IIf(IsNull([Issues]![Actual Closure Date]),DateDiff("d",[Issues]![Target Date of Closure],
Date()),DateDiff("d",[Issues]![Target Date of Closure],[Issues]![Actual Closure Date]))
How do I calculate the values between two columns and populate a third column with those new values? I have an ''Actual Cost'' column and ''Budget Cost'' column and I would like to create a third column ''Margin.''
Is this something that needs to be done with a query or can it be handeled in the design view of a table? I'm starting to learn that Access works nothing like Excel.
Thank you in advance for any help. I scanned some of the threads in this forum, but many were beyond my comprehension. Any walk-through of this procedure would be much appreciated.
Hello,
I,ve made the following date fields in a form: begintime, endtime. I've also made a field Diff that calculates the difference between the two by the code : Diff = Format([begintime] - 1 - ([endtime], "Short Time").
Bij this code you can calculate the difference even over night.
But now I've got to calculate the part of the time someone worked between midnight and 06:00AM if that person indeed worked in those hours.
e.g. someone started at 16:00 end ended at 03:30. The part of time I need = 3:30
e.g. someone started at 01:00 end ended at 11:00. The part of time I need = 5
How can I accomplish this? I hope someone can help me because I'm :confused:
Thnx Remco

I have looked all over for a way to calculate the difference between water meeter readings. My brain may be Friday slow, but all I can find is for calculating differences in dates. My water table has 3 fields: ReadDate, Reading, Calc1
ReadDate is the date the water reading occurred
Reading is the meter reading
Calc1 is calculated (when I find out how!) by subtracting the current reading from the previous day's reading.
I would like to add the write script in my form so when the readings are entered, the calculation auto populates the field for the user.
I'm new to building databases and I wouldn't think that this is difficult but it has stumped me and everyone that I have approached to elegantly perform this calculation.
Essentially I have a table of meters (the best real world example is the watermeter that your community uses to measure how much water you use each month.) Each meter in the table has a "child table" of the date/time that the meter was read and the reading on the meter (stored as a number). I need to calculate the difference between the last two readings in the child table for each meter(essentially how much water each meter has used since the last reading.)
I have been able to sum, average, etc. the meter readings, but I can't seem to find a way to get a difference.
Thanks in advance,
Corwin
I am trying to Calculate the Date difference between "Material Submit Data" and "Current Date" excluding Weekends.
View 2 Replies View RelatedI'm trying to calculate the difference between start and end time, which works fine with:
Total Time: DateDiff("n",[tblTaskTimes]![StartTime],[tblTaskTimes]![EndTime])
However, this is for a database that calculates billable time in 10th of an hour. So, for example, 1 hours would be 1, 30 minutes would be .5, less than 6 minutes would be .1.
The format for this expression is set up to a general number, if that matters.
It's gotta be something in the formula like multiplying this by 24 (for 24 hours) and then dividing by something. Nothing I'm trying is working.
Trying to calculate the integer difference between Due_Date and Result_Date excluding weekends and holidays.
I have a table (Holidays) with the dates of the holidays in it. The table looks like:
ID Description Holiday
1 New Years 1/1/2014
2 New Years 1/1/2015
So, if Date_Due: 9/25/2014 and Result_Date: 9/29/2014, then TAT = 2
Since 9/27/2014 and 9/28/2014 are weekends they are excluded from the calculation and only that Thursday and Friday are used in the calculation.
Code:
Private Sub Result_Date_AfterUpdate()
[TAT] = NETWORKDAYS(Due_Date, Result_Date, tblHolidays)
End Sub
How to implement a functionality into my access database. The related tables required for this functionality can be found as an attachment.
When the information has been entered into the tables by the user, I would like to calculate the difference between the information for each part within the same table. The main columns for which the difference have to be calculated are: [RefObsInfo->RefSources] and [AltObsInfo->StatusAltSource] and [GenObsInfo->GenSources]. The values for these fields are restricted to 3 or 4 different ones. I also would like to show if the GenEstAvailable columns are changed, but that's for later.
In order to calculate this difference a query has to select for each Part the information related to the last date AND a date which has been specified by the user (with the previous date as max). For this the user is asked to give a from date, which she/he can select from a combobox. This combobox has a standard selected value which is the MaxDate-1, i.e. the previous date. The difference should be calculated from the previous date to the last date. I would prefer to give each (predefined) difference a specific action to show the user the difference in a matter of seconds.
I have a subform in which I want to calculate the difference between a start time and finish time, the problem I am having is when the start time is on a different date to the finish time
Start 23:15 on 14th Jan finish 00:015 on 15th Jan, also I want the answer to be the number of minutes. The fields I have are
BatchStartTime Short Time
BatchFinishTime Short Time
BoilTime ([BatchStartTime] - [BatchFinishTime]) General Number.
There are many batches to enter per job and the MainForm has the StartDate as I didn't want to enter the StartDate for each batch.
