Query Calculating No Of Days Between Start And End Date
Mar 20, 2007
i am trying to run a query from a form which will bring up the no of days difference between the start and end date also on the same form.
The query doesn't bring back any results can someone please guide in what i am doing wrong.
Here is the query
SELECT DateDiff('d',[start date],[end date]) AS [no of days]
FROM [booked property]
WHERE ((([booked property]![start date])=[forms]![booking]![booked property]![start date]) AND (([booked property]![end date])=[forms]![booking]![booked property]![end date]));

I have form which automatically takes a start value for today the fieldname is Date.
Now what I want to do is calculate the difference between Date and Today's date in days with 2 criteria's
Ist criteria will be choosing the field which has a boolean field named Was Issue Resolved and has value as Null or False and
2nd criteria will be to show only days with greater than 21 days
This is what I m trying to do
Expr3: DateDiff("d",[Date],[date()])
but gives me error on date() as it can't find this parameter
I tried this also: >=DateAdd("d",-21,Date())
But its not population difference between the Date and Today Date ...

I'm working on a query ("Target Date of Completion") that takes the initial date started (from Step 1 of date started) and adds the EC (Estimated Completion) which is just shown in days. This will give an EST (Estimated Start time) for the next step in date format, which I would need the new column. Also, As you can see, the piece parts all have a different amount of steps, so this calculation would need to know when it's a different part.

I am calculating number of weeks between start and finish date. Some of the users have questioned the validity of calculation as they are not too sure if this is being calculated as Monday to Friday week or does it work by calculating 7 days. If the latter is true, then I should see a decimal value. I am using date diff formula.

I am trying to calculate the working days Based on all web searches I am unable to find the specific scenario I am working in Auto industry, which means auto industry usually close twice a year for any reasons, let say in July for one or sometime two weeks and in December depends upon the Christmas date usually from December 20 till Jan 01
Now my question is when i am enter the holiday details in table do I have to enter line by line date e.g. july 01, 02, 03 (I am able to understand, how this works but still not yet tried) OR july 01 to July 07 (which make sense, but unable to find how to use date range to calculate working days)...

I've attached a stripped down version of a small order database I'm working on.
A user would enter an order, the amount and the date the order is required by.
As you can see from tbl_seasons, the business has financial periods that match the first and last 6 months of each year. Each season has a start date and end date.
What I'm trying to build are two queries:
1. A query which lists all orders and has an extra field which shows the "season_id" that the order (date) relates to (based one the start date and end date in tbl_seasons)
2. A totals query which shows the total order amounts by season
how I might build these 2 queries.

I have four date/time fields and I need to determine the number of days and the number of hours between them based on report date range. The Days need to be in one field and the hours in another field. I have tried DateDiff function with an IIF condition and get the following negative value in Expr1. If I remove the IIF condition then I get a positive value.
If the date in field 1 is less than field 3, the days and hours need to be calculated field 2- field 3 as long as field 2 is less than or equal to field 4. If field 2 is null and if the date in field 1 is less than field 3, the days and hours need to be calculated field 2-3 but if field 1 is less than field 3 the calculation would be field 4- field 1. When both dates are within the report range then DateDiff works fine.
Adm Date [/U](f1) D/C Date/Time (f2) Beg Report (f3) End Report (f4) Expr1
I could e-mail the table with sample dates if this would help
Can anyone assist me with this formula?????:mad:

I have a form with two date fields: "Initiation_date", and "Correction_date". There is a third field called "Duration". I would like to store the values of all three fields in the corresponding table. "Duration" (Long Integer) would be the number of days from "Initiation_Date" to "Correction_Date" if Correction date is there, or to Date() if Correction date is Null.
I can use an unbound text box to get "Duration_cal" using the following as a control source:
=IIf(IsNull([VCor_date]),DateDiff("d",[VInit_date],Date()),DateDiff("d",[VInit_date],[VCor_date]))
But I cannot get that value (No.of Days) in to the "Duration" field. The reason I want to have "Duration" stored as a number is that it is being used in a query for another calculation (total days used for selected records).
Is there a simple way to accomplish this?
Thanks

I have a query and I need the records to display 3 working days before the 15 working day deadline.
I used the following in the criteria box below the received date field and it doesn't pull the correct number of workdays, it's pulling calendar days instead.
<=DateAdd("w",-12,Date())
Can anyone help, thanks for your time!!!

I'm trying to breakdown a date into years, months, and days. Simple right?
The code I've been using for months returns a negative month if it happens to be the next month. Instead of returning 1 Year, 1 Month, 23 Days, it will instead return 1 Year, -1 Month, 23 Days.
Code is:
Code:
Months: IIf(IsNull([TIR]),0,IIf(Day([TIR])<=Day(Date()),DateDiff("m",[TIR],Date())-[Years]*12,DateDiff("m",[TIR],Date())-[Years]*12-1))

I am trying to calculate the number of days between incidents.
If I have an incident that happened on the 10th August and another on the 15th August then this would be 5 days, the next incident occurred on the 28th August so that would be 13 days. The problem I am having is how to get access to use the latest date rather than the first date.

Find the difference between two dates is simple if you're simply looking for the number of days between them. However, if you're looking to express the difference in a bit more user-friendly way, you can use the following code to calculate the difference in years, months, and days. The code accounts for zero values, plurals and the Oxford comma. Further, it automatically sets the later of the two dates to the End date, so the dates can be used interchangeably.
Examples:
June 4, 2010, July 3, 2012 returns "2 Years and 29 Days"
June 4, 2010, July 5, 2011 returns "1 Year, 1 Month and 1 Day"
June 4, 2010, June 5, 2010 returns "1 Day"
Code:
Function DiffOfTwoDates(dtmDate1 As Date, dtmDate2 As Date) As String
' Written by Will Knapp, Freelance Access Developer, 2013
Dim dtmStart As Date, dtmEnd As Date
Dim strDiff As String ' Resulting String
Dim yDiff As Integer ' Year Difference
Dim mDiff As Integer ' Month Difference
Dim dDiff As Integer ' Day Difference
Dim CommaLoc As Integer
[code]....

I am using workdays to calculate time passed between two dates. I also have a table for Holidays that I don't want counted as work days. This is working well, but I would like my queries to show a null value instead of showing #Error when a date field is empty. Here is my coding in my Module.

I'm trying to work out the difference between 2 records both of which have a call out date [bas start date]..basically the structure is
equipment number call number bas start date
12345678 112255 1/7/14
12345678 112256 3/7/14
What i'm after is the 4th column to work out the date diff... in this case 2 days the equipment can be multiple times so i might see equipment number 12345678 - upto 10 times with consecutive dates - all of which i need to know the difference between the current call date and the previous call date..

I have attached a sample of a database.
Table 1 has all the items I am trying to sell with sell by date after which I cannot sell this item. Then in Table 2 I have forecasted sales. So now I am trying to calculate stock consumption to see if I will be left with any stock that I cannot sell.
So now somehow I need to deduct sales forecast from my stock holding but it needs to go by date i.e. consume all stock for Item 1 with date 16/09 before moving to Item 1 with sale by date 23/09.
So based on the attached example, I can see that on 16/09 I will consume only 5 cases from sell by date 16/09 and another sale is 18/09. So that would give me information that I will be left with 95 items dated 16/09, which I cannot sell because they will be out of date.
Ideally I would like also to include the logic that if Item is out of date it would move to the next sell by date.
So in this case sale of Item 1 forecasted for 18/09 (94) would consume the whole stock (50) with date 23/09 and another 44 from date 01/10
For Item 2 I can see that units with Sell by date 30/09 will be consumed on 25/09 and I will start taking stock from next sell by date which is 14/10.

I have a DB with Start Date (dd.mm.yyyy), End Date (dd.mm.yyyy) and Quarters. We have 4 Quarters (Jan-March, April-June, July-Sep, Oct-Dec) and extra columns of month (xxx) and year (yyyy) too.
The problem is the front end users have access permissions to modify the dates. if they change the start date and end date then they are manually gonna change other fields like quarter, month and year too (Which they don't want). The users don't need to manually update the column values for Quarter, Month and Year
For Example,
If the user modifies Start Date to: 22.05.2014 and End Date to: 24.06.2014 (then the quarter column should be fixed to 2nd quarter and month should be June and year should be 2014).
2nd Example: We need to consider the End Date for classifying the quarters, Month and Year
If the Start Date is: 22.05.2014 and End Date is: 24.12.2014 (then the quarter column should be fixed to 4th quarter and month should be December and year should be 2014).
The solution is when ever the front end user modifies the dates then automatically the quarter, month and year columns need to be changed.
Sample piece of Access data sheet with just 3 examples. Column names Start date, End date, Quarter, Month, Year.

I manage training for a large organization and am able to get a data dump that contains class end dates and class hours. Based off of those two, is it possible to determine a start date (excluding non-business days)?
For example, a 2 day class would be 16 'Hours' with an 'End Date' of Friday the 15th. Is there a formula that would give me Thursday the 14th as a 'Start Date?'
More importantly, if 'Hours' is 80 and the 'End Date' Friday the 15th, would it be able to give me a 'Start Date' of Monday the 4th? Can Access account for holidays?

Right now I have this in the query criteria row:
>=[Enter Start Date:] And <=[Enter End Date:]
This makes two prompts pop up one at a time. I was wondering if there was a way to combine both start and end date boxes in one prompt so I can see what dates I decide to type side by side. Is this possible?
