Problem With Calculating Days Between Dates
Dec 9, 2005
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 that records a status update, and the date it was made by an employee etc. The table has a secondary key related to ... lets say a project table.
E.g.
Status Id; EmployeeID;ProjectsID;Status;Date
I want to calculate the average amount of days it takes for a status change occur.

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 have a form called subfrm_vactions
rowsource is a query called qryVacations
the query should calculated two things
1 - the difference between start_vac and End_vac in days to calculate the vacation period and put the value in field called Period (working well)
2-the work days which the period between the last day in Previous record (End_Vac) and the (Start_Vac) in the next record (didn't work)
the result is the difference between (End_Vac) and (Start_Vac) in the same record which i don't want
simply i want to calculate the work days.

I have a form where a start date is inputted (Inputfrm , StartDate) and a form where the end date of the process is recorded (Inspectionfrm , EndDate) and these both record in the table InputTbl as StartDate and EndDate respectively.
I have created a union query which shows a list of all the dates where there is work recorded (WorkingDatesQry and the column of list of unique dates is "WorkingDate"), and as we run a highly varied schedule depending on time of the year and order numbers I cannot just use a query which says Monday-Friday or Tuesday - Saturday.What I am trying to do is to find the number of days between StartDate and EndDate where there is a date recorded in the WorkingDates query.

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:

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'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.

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.
Option Compare Database
Option Explicit
Public Function Workdays(ByRef startDate As Date, _
ByRef endDate As Date, _
Optional ByVal strHolidays As String = "Holidays" _

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)...

Hi,
I need to work out a couple of calculations, the number of days between an engineer starting and finishing a project, the number of days between the project being put on the database in the first place and being completed by an engineer and finally, the difference between these. These maybe simple, but I have no idea tbh (still new to access).
I have a form with the date it was added onto the database, and the engineer fills in the date started and date finished as it happens.
These run off of 2 tables BookingIntbl and TechnicalServicestbl
[BookingIntbl].[Date], [TechnicalServicestbl].[Date Started] and [TechnicalServicestbl].[Date Finished]
I have then got the fields, 'Days with Engineer', 'Days in Repair Centre' and 'Day Difference' for the answers to be displayed.
Any help would be appreciated, Ben

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.

DateDiff("w", StartingDate, EndingDate)
that also makes sure date is not in tblHolidays.

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!

I want the number of days between a specific date (roll out date) and 12/31/2005 so that
I can use the number to project revenue for this year.
This is what I'm using but it doesn't give me the right number. I don't know how to transform
something to a datetime variable so maybe that's the reason. Can you help me out?
Expr4: Day(12/31/2005-[Scheduled Roll Out Date]-0.49999)

I would like to count the number of working days between two dates, NOT the calendar days, if the workers only work Monday thru Thursday. I know we could use the DateDiff function, but HOW do I count excluding Fridays, Saturdays, Sundays?

I have a table "main" with 2 colums (main_id,date_out). This table has a link to the table "refill". This table has 3 colums (refill_id, main_id, refill_date).
Example data:
TABLE MAIN
main_id - data_out
01 - 01/01/2006
TABLE REFILL
refill_id - main_id - refill_date
01 - 01 - 10/01/2006
02 - 01 - 16/01/2006
03 - 01 - 21/01/2006
When I make a simple selectquery with the fields main.date_out and refill.refill_date I become the the next result.
01/01/2006 - 10/01/2006
01/01/2006 - 16/01/2006
01/01/2006 - 21/01/2006
Now the problem.
I have to calculate the days between the main and refill dates
01/01/2006 - 10/01/2006 ( is the same as above)
10/01/2006 - 16/01/2006
16/01/2006 - 21/01/2006
suggestions????......thanks

Hello to everybody.
I have a problem in calculating the difference between two dates and displaying the output into Years Months Weeks Days. My problem is that dividing the number of days by 30 and requesting an integer is not accurate enough. I have looked at Pat and Jons examples shown in these threads
http://www.access-programmers.co.uk/forums/showthread.php?t=67472
http://www.access-programmers.co.uk/forums/showthread.php?t=89051&highlight=calculating+number+months
which either method would suit me as the accurate answer is what I am after.
My problem is that not all of my records would have a start and end date. Therefore both examples would result in an error.
Can anyone please give a hint on how to perform the calculations on those fields which have dates recording the results but ignoring those fileds which do not have a start / end date.
I am having a bad day and I'm sure the answer is so easy that I am going to kick myself but having played around with the modules by limited knowledge is not enough.
Many thanks in advance
Ian

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).
