Queries :: Calculate Number Of Days Between Two Dates Using IIF Statement?
Nov 21, 2014
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])))

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]))

I am making a basic hospital management system in Access 2013.I have two tables named "Bed" and "Receipt". Bed(BedID,AssignedDate,PatientID,DischargeDate,Bed Charges) Reciept(ReceiptID,PatientID,BedCharges) I want to calculate "BedCharges" by calculating the number of days using "AssignedDate" and "DischargeDate" and then multiplying with a constant amount of charges per day. Also the BedCharges calculated in "Bed" Table also needs to be in the "Receipt" table. How can I count the number of days and then calculate the "BedCharges" in both the tables?

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'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.

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 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!

I'm trying to create a sub to count how many days between 2 dates excluding Holiday and weekend. Using the DateDiff() function is not allowing me to exclude certain days.

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).

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?

In a database, I have the following date fields that I use to track projects that start and stop.
START1
STOP1
START2
STOP2
START3
STOP3
Is there a way I can use a query to calculate the total days the project was worked on? For example if I enter 1/1/06 in START1, 1/10/06 in STOP1, 2/1/06 in START2 and 2/15/06 in STOP2, 3/1/06 in START3 and 3/30/06 in STOP3, I need to calculate the total days. I need it to work regardless if there are 3 start/stops, 2 or just one start/stop.
I really appreciate the help.

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)

I have a contract management database where contracts have a start date and an end date. I also have a date parameter set up whereby I can show live contracts between overlapping records.
I want to be able to count the number of days for each contract that is live between the dates of the parameters.
For example my contract might run from 1st to 30th November but I might want to report from 10th October to 10th November so the number of days I need the query to return is 10 days as my contract is not live before the 1st November. Or my query might run from 1st October to 31st December, then I would need it to show 30 days as it covers the whole of this contract.

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 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)

In my table I have the following 4 fields with the associated date field:
Bronze: 11/1/2013
Silver: 5/1/2014
Gold: 11/1/2014
Platinum: 5/1/2015
I am trying to calculate a value based on comparing the current date to the dates in these fields. I am using the below formula. However, using 6/27/2013 as the current date, my formula keeps resulting in "Bronze" when it should result in "Standard" Am I doing something wrong?
=IIf(Date()<[Bronze],"Standard",IIf((Date()>=[Bronze]) And (Date()<[Silver]),"Bronze",IIf(Date()>=[Silver] And Date()<[Gold],"Silver",IIf(Date()>=[Gold] And Date()<[Platinum],"Gold","Platinum"))))

Basically, 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
[code]...

I'm using the following function to calculate date diff in network days (excluding weekends)
Public Function NetWorkdays(dteStart As Date, dteEnd As Date) As Integer
Dim intGrossDays As Integer
Dim dteCurrDate As Date
Dim i As Integer
intGrossDays = DateDiff("d", dteStart, dteEnd)
NetWorkdays = 0
[Code] ....
So when using this function in a query to get number of networkdays between 2 date columns ...it works fine but throws a #Error where there is blank entries in either of 2 date columns...
I need to find a way to display Null instead of #Error...
I have tried this expression but no luck...
IIf(IsError(NetWorkdays([Date1],[Date2])),"",NetWorkdays([Date1],[Date2]))

My database keeps track of training for employees, some of which expires after a period of time, which is in the tables. I need to create a query that displays only the employees and the training that expires during the next 30 days. I have a query that displays the expiration date (this field uses DateAdd and adds the expiration term to the date the employee completed the training) I am trying to add a criteria to this field. I found <=Date()+30 in my searches but that displays all of the records from 12/14 and back. I have tried all kinds of versions of this (obviously, not the correct one) and either get all records or none. (Yes there are records in the database that fall within the the period I am trying to display - that is something that I have been known to forget)
Is it because I am using criteria in a field that is based on DateAdd or what would be the correct criteria for this?

I have 2 dates that I need to count between. Easy enough just use the datediff right? Nope cause it won't count just the 5 workdays. I researched and found that the "w" in the function doesn't work the way I need it to. I found lots of code to make a module that will do it for me and they all include having a holiday table. Right now I don't need a holiday table I just want the simple dates in between.
