Date Calculation Help!
Nov 4, 2005Hi, I have a table that has a start date field, a duration field and an end date field. I was wondering what I need to do so that the end date is calculated and entered when the duration is added onto the start date to produce the end date?
Should the date fields be set as a date, data type?
Sorry if this does not make sense ;)
Many thanks, Tobi

Date Calculation
Sep 9, 2005Here is the scenerio:
I have two tables:
tblDate: Contains on Months (i.e.Jan, Feb, Mar, etc)
tblActivities: Contains 4 fields Name, date, activity and hours
I have greated a form that allows me to select what month I want to see. It has a simple combo box in it that point back to tblDate.date. I setup a macro that is doing a OpenReport, there Where Clause is as follows:
[Forms]![frmMnthSelect]![Combo0] Like [tblVolunteers]![Date]
Of course this is not working, and I am at a loss.
I have a Query that is setup that is pulling all records for the current month, but I need to be able to select individual months, because I often have to pull reports for past and future projects.
Can some one start me out in the right direction......
Thanks,
Chuck
Excel Date Calculation
Nov 21, 2005Hrmm, im sure there used to be an Excel forum, i seem to have lost it :/ Hope its ok posting here:
What im trying to do is, for a range of dates from 1/1/2005 to 31/12/2020 get the Qtrly Financial Period before...
So, for instance:
A date of 1/1/2005 makes the period before 1/10/2004 to 31/12/2005
A date of 1/5/2005 makes the period before 1/1/2005 to 31/3/2005
A date of 1/8/2010 makes the period before 1/4/2010 to 30/6/2010
Fiscal Period (for those that dont work with them) are, 1st April to 30th June, 1st July to 30th Sept, 1st Oct to 31st Dec and 1st Jan to 31st March of any year.
So what i want is 3 colums in excel, Column 1 = Period Start, Column 2 = Period End, Column 3 = Date
Can anyone figure the forumla out? Doesnt matter where its done in, just as long as the end result can be in Excel....

Date / Time Calculation Help
Jul 13, 2006I'm having trouble getting my head around this.
I have a database that collects stats of patients admitted to ICU.
I have a table PtDataTable (pk = PtID) with a one to many relationship with PtVisitTable (pk = VisitID, fk = PtID). The patient visit table has the fields AdmissionDate and AdmissionTime, and DischargeDate and DischargeTime.
I need to calculate if the patient is readmitted to ICU in less than or equal to 48hrs. In other words calculate the time elapsed between DischargedDate and DischargedTime in one record and the AdmissionDate and AdmissionTime for other records in the PtVisitTable for the same patient.
I'm not sure if I stated this clearly.
Any help is appreciated as always.
Date Calculation In Query
Apr 20, 2007YearsOfService: DateDiff("d",[Employee]![SIV Date],Date())/365
First I'm calculating the current Years of Service. SIV Date = Hired Date
Then I would like to calculate the years of service as of 12/31/"Current Year", where the Current Year would not require updating every year and 12/31 would be constant.
I'm just not sure how to specify the Month/Day and use Current Year not hard coded. I could set up a user defined date for that half of the calc but my users are not really bright and allowing them to simply click a button is my only option there.
Ultimately I will compare the 2 years of Service numbers to determine if there will be a change in the level of vacation accrual an individual receives during the year. The only part I have issue with is coding that date. Thanks for the help.
Review Date Calculation
Aug 28, 2007Hi
I have a database for maintaining procurement contracts which includes a start date for each contract and a frequency of reviews required (monthly, qrtly, bi-annual, yearly). I need to be able to generate a report that will tell me when the next review is due for each contract, taking today's date into consideration.
This is the setup so far:
tblRegistry - contains field 'Commence' for the start date of the contract and 'Review Req' to indicate how often a review is required (monthly, yearly etc).
tblReviewReq - contains field 'Review Frequency' (monthly, yearly etc) and 'Days' to assign the number of days eg monthly = 30, yearly = 365 etc.
Next I have a query that includes the above tables using the fields 'Commence' and 'Days' and have created a calculated field to give me the next review date ie contract start is 1/08/07, review freq is monthly (=30 days), therefore the next review is 1/09/07. "NextReview:[Commence]+[Days]"
But how do I get it to tell me the next review date after the 1/09/07? Ultimately I'd like to be able to pull a report at any stage which will tell me all the reviews that are coming up.
Thanks
Date & Time Calculation
Dec 19, 2007Table
------
I have one field called [Time] in dd-mm-yyyy hh:mm format in table A.
I have another field called [Deadline] in text format (Mon 10:00) in table B.
Queries
-------
Need to build one queries that have the above two field, but with additional field called [PullDeadline] that the [Time] will look out the [Deadline] and return the actual time & date value in [PullDeadline]. No matter how the [Time] change, the [PullDeadline] will stick to [Deadline] and return the value in that particular week.
For example,
[Time] = 01-12-2007 05:00:00 AM
[Deadline] = Mon 10:00
[PullDeadline] = 26-11-2007 10:00 AM
How to handle, if the deadline is previous or next week?
Eg. [Deadline] = Sun 10:00
Then [PullDeadline] = 25-11-2007 10:00 AM instead of 02-12-2007 10:00 AM.
Forward Date Calculation
Mar 10, 2008I need to use an update query to calculate the following 1st of April for each of 3000+ records, the only exception is if the Start Date is the 1st of April in which case the date will remain the same.
Examples
StartDateAdjStartDate
01/03/08 01/04/08
10/09/06 01/04/07
15/04/08 04/04/09
01/04/08 01/04/08
Can anyone advise the best way to do this?

Variable In A Date Calculation
Aug 14, 2005I have the following date calculation :
-----------------
Private Sub StatofLimits_GotFocus()
'--Determines Statute of Limitations accounting for minors.
If DateAdd("yyyy", 18, Me.Txt14) > Me.txtBegin Then
Me.StatofLimits = DateAdd("yyyy", 20, Me.Txt14)
Else
Me.StatofLimits = DateAdd("yyyy", 2, Me.txtBegin)
End If
End Sub
------------------------
Here is my problem. The number "2" in the else statement (Me.StatofLimits = DateAdd("yyyy", 2, Me.txtBegin)in the above example is a variable. The variable is selected from a combobox and stored in an unbound textbox. The variable will always represent a number of years-ie 3 years, 4 years, etc. I need to modify my calculation so that it will pull the variable from my textbox:
I know this isn't correct but this is what I need:
Me.StatofLimits = DateAdd("yyyy", (Number from MyTxtBox), Me.txtBegin)
Can anyone give me the correct syntext?
Pat, If you read this, I did listen. The reason I need to modify my calculation and use a variable is because I moved my Statute of Limitation Dates to the same table and different case types have different Statutes. They can be anywhere from 2 to 6 years.
Calculation Based On Date
Aug 29, 2006I am not sure how to do the following and appreciate any help offered.
I need to have create an expression that gives me a total based on the number of days (different arrival and departure dates) where each day has a different value but remains the same from record to record. Perhaps this is a very easy thing to do, but I am just missing it.
Thank you
Time And Date Calculation
Oct 15, 2006OK so I have a form with the following fields which are all date/time type
apptTime
timerOn
pickupDate
reminder - combo box with 1 hour, 2 hour...etc up to 10 hours
so what happens is when user enters apptTime say 18:30 with pickupDate set for current days date 10/14/2006 then chooses 2 hours from the reminder combo. This then sets timerOn to (apptTime-2 hours) so it is 16:30. I have set a conditional formatting to change background color when "timerOn<=Time() and pickupDate=Date()" so user knows to dispatch this load. This all works great until you get to midnight.
If user sets apptTime to 00:30 with pickupDate to 10/15/2006 and chooses 2 hour reminder, so timerOn does get set to 22:30 and you would expect the conditional formatting to work once the current Time() is 22:30, but since the current Date() is 10/14/2006, the expression is false. I have tried the DateAdd such as DateAdd("d", 1, Date()) command in various ways but can't get it to work for "timerOn<=Time() and pickupDate=DateAdd("d", 1, Date())"...I mean it works because it adds 1 day to pickupDate and condition is then true, but it ignores the timerOn<=Time() part and formats even if I reset system time to 22:29. Can anybody give me insite on where the logic is wrong?
Using Nz Function In A Date Calculation

If i have a calculated field
=DateAdd("d",7,[DateSubmitted]) then how do I deal with the possibility that [DateSubmitted] may be blank??

Age At Specific Date Calculation
Apr 3, 2007Hi
In need of some assistance please.
I am looking to calculate in a form someones age in years and months at a specific date.
I have tried various different functions but can't seem to work out where i'm going wrong.
The persons date of birth is entered manually into the "DoB" field. I then want their age to be calculated in a text box below this, if it needs 2 text boxes then so be it.
The specific date is 25/05/2007 (UK date).
I am currently using the datediff function but I need the calc to be more specific than just the year.
Hope this makes sense.
Thanks in advance
Calculation On System Date
Feb 19, 2012I am developing a small application for a school. In the school they teach 5 subjects in five periods. One period's time in 40 minutes. I want to develop a table which will display the next period after previous period is over. The computer must skip to next period on the basis on system time.

Feb 17, 2015Access 2007, Windows 7
On a form I have 2 textboxes, 1 for user input, the other a calculated date. The two values together represent a "Leave Year". The second textbox contains, [Firsttextbox]&" - "&([Firsttextbox]+364). Simple enough so far. The expected result from entering, for example, 2/10/2015, is 2/10/2015 - 2/9/2016, which is exactly what I need. But, using a hard figure like 364 will fail on 3/2/2015 when the extra day in Feb 2016 results in, 3/2/2015 - 2/29/2015. To compensate for this, I've added,
"=IIf([Firsttextbox]>"2/28/2015",1,0)" to a third textbox and added it to the calculation as follows;
[Firsttextbox]&" - "&([Firsttextbox]+364+[Thirdtextbox]) So far so good....almost.
The "Leave Year" calculated is what I want, until 10/1/2015, when something goes awry. At 10/1/2015, the expression in the third text box evaluates to 0,and I lose my extra day.
If the calculation is an Access 2007 problem/issue, will it evaluate correctly if it's migrated to a new version?
Another thing I need to do is similar, in that a date is entered and calculated to 7 days prior. If the calculated date falls on a Saturday, I need to have it adjust to Friday, the day before. Also, if another calculated date falls on Saturday or Sunday, I need to have it adjust to the following Monday. These are two separate calculated fields, but both are necessary.
Problem With Calculation From Date Criteria
Aug 13, 2006Hi, I have a membership database I'm working on and the problem I'm tearing what's left of my hair out over is this:
If the date of joining the club is <= 15th of that month then the renewal date is 1st of that same month in the following year.
However, if the date of joining the club is >15th of that month then the renewal date is 1st of the following month in the following year.
I hope that makes sense/ Example:
JoinDate = 03/08/06 then RenewalDate = 01/08/07
BUT IF
JoinDate = 16/08/06 then RenewalDate = 01/09/07
Any ideas on how I would go about doing this would be greatly appreciated.
I realise that I could simply use the DatAdd() function to add an entire year to the JoinDate, but as you see the criteria I have to work to is unfortunately not that simple.:(
Thanks hopefully.
Calculation/Date Rang Problems
Jul 25, 2006Hey Y'all,
Well...where should I start? This db report has a few calculations in it, so let me explain them real quick. The db tracks work assessments that are categorized as Pass, Fail, or Non-Rated.
The first is an overall percentage rate of all assessments. Non-Rated assessments are not included in this query. It works fine. In the report it's the Group Total.
The second is a "maintenance" percentage, which is calculated from just two types of assessments. This also works and in included in the report in a sub-report. This is the Maintenance Rate.
Our guidance has recently changed, and I'm trying to incorporate these changes. The first one is an addition to the first/overall percentage. The Group Total is
Rate: IIf([Var1]+[Var2]=0,"N/A",[Var1]/([Var1]+[Var2]))
where Var1 is Pass and Var2 is Fail. This works fine for an overall percentage. However, now we need to deduct 0.5 points for each type inspection "TDV", "UCR", "GO", or "DSV." These are some of the assessment types listed as Non-Rated, however, there are other assessment types listed as Non-Rated that are not part of this criteria.
I included this change in a separate query "qryGroupDeductions." In this query, the 0.5 point per specified-assessment type is calculated by grouping and counting these inspections, then multiplying them by 0.5
DeductPoints: [DeductionCount]*0.5
This query counts and calculates properly. In the report there's a bit of conditional formatting that's been working so far. I had problems w/ it, but I think it's working properly now.
Private Sub GroupHeader0_Format(Cancel As Integer, FormatCount As Integer)
If Me.Text64 <= 1 And Me.Text64 >= 0.95 Then
Me.Text66 = "Outstanding"
End If
If Me.Text64 <= 0.9499 And Me.Text64 >= 0.9 Then
Me.Text66 = "Excellent"
End If
If Me.Text64 <= 0.8999 And Me.Text64 >= 0.8 Then
Me.Text66 = "Satisfactory"
End If
If Me.Text64 <= 0.7999 And Me.Text64 >= 0.7 Then
Me.Text66 = "Marginal"
End If
If Me.Text64 <= 0.6999 And Me.Text64 >= 0 Then
Me.Text66 = "Unsatisfactory"
End If
If Me.Text66 = "Outstanding" Then
Me.Text66.FontBold = True
Me.Text66.ForeColor = 8388608
End If
If Me.Text66 = "Excellent" Then
Me.Text66.FontBold = True
Me.Text66.ForeColor = 6723891
End If
If Me.Text66 = "Satisfactory" Then
Me.Text66.FontBold = True
Me.Text66.ForeColor = 0
End If
If Me.Text66 = "Marginal" Then
Me.Text66.FontBold = True
Me.Text66.ForeColor = 65535
End If
If Me.Text66 = "Unsatisfactory" Then
Me.Text66.FontBold = True
Me.Text66.ForeColor = vbRed
End If
End Sub
The problem I'm running into is when you run the queries/reports for a period longer than a month. The instructions on the new guidance don't take into account quarterly or annual reports. When this report is run for periods longer than a month, the 0.5 point deduction makes a disproportional difference because you are deducting a sum from an average. The larger the time-span in the query, the larger the deduction is.
That, my friends, is the problem. I've made one query (qryQtrGrpDeduction) that "solves" this problem. It's based on the "qryGroupDeductions", and uses a basic calculation to create an average for the months.
QtrAvg: [DeductionCount]/3
and
DeductPoints: [QtrAvg]*0.5
This is very basic, but effective. But using would create a much duplication of queries and reports. I would need one set of reports/sub-report/queries for the month, quarter, and the year. This sample db doesn't show it, but our working database does this same calculation for four different organizational levels....So in using this method, we would need approx 15 queries and reports.
Not cool.
There's gotta be a way to effectively accomplish the requirements w/o creating a multitude of reduncies.
BTY, I'm using Access2003.

Date And Time Format Calculation
Jul 13, 2007Hi,
I need to calculate the number of days between two days however the format on which i have my date includes the time in the same field -
2007-02-20 07:15:30.474
When I calculate one date minus an other the result is #error
I require the result to be in a count format e.g 2.3 days (like in excel)
Is there anyway to get around this without splitting the date and time?
Please help!:)
