Modules & VBA :: Calculating Number Of Days Between Records
Sep 10, 2013
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
I've been searching the Queries Forum for help on this issue. I have a database that records loading records for a Taconite facility. Some days contain many records and on other days there are no records because of no loading activity. I create reports that group these loading records by each day, but I really need a quick and dirty report that just shows me the number of days in any month in which we had loading activity (records present). I have not figured out a way to create a query which counts the number of days in a month which contain records. I'm hope I'm explaining this well enough for someone to help me understand what to do.
My subreport provides appointment stats for every month and is grouped by month in the main report. I manage to include the number of days for each month using:
I am using the following UNION QUERY to total up equipment tested for a report.
SELECT "Laptops Tested" AS PCEQUIP, Count(*) AS RECORDS FROM [LAPTOPS] WHERE (((Date)Between [Enter Start Date] AND [Enter End Date])); UNION SELECT "Workstations Tested" AS PCEQUIP, Count(*) AS RECORDS FROM [WORKSTATION]
[code]...
I have created a report using ACCESS 2000 for this union query and it satisfies the requirement. I am trying to add the proper code and syntax in this query to total the number of all of this equipment tested.In this case the total would be 86. Is this possible?
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:
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:
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).
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'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.
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 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.
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" _ ) As Integer
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 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.
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 imported an large Excel file with a date column consisting of 3 different date formats and need help on a query to extract the number of days. Examples of the date on that column:
I have created a database which allows people to enter in when they are off sick. They have to enter in the FIRST DAY of sickness and the LAST DAY of sickness. All of this information is stored in one big table - SICKNESS TABLE. There are no other date fields in that table.
I want to know how many people have been off for 5 TIMES OR MORE in a 365 day period (which may be say, from Oct 2005 to Nov 2006 - so not always in the same year).
I have managed to get a query that will count the number of times someone has been off; but that could be over, for example, 2 years.
How can I get it to tell me if someone has been off for 5 TIMES OR MORE in a 365 day period???
