Queries :: Date Difference Excluding Weekends And Holidays
May 6, 2014
Is there a way, in a query or via the use of a module, to calculate the workdays between two dates excluding holidays without needing to maintain a separate table with the holidays listed out?
For example, I would like it to calculate 21 work days for the month of May. However, I don't want to have to go in the first of each year and manually list out all the holidays for the year. Is there a way for the Holidays table to just contain the number of holidays in a given month (i.e. in December we get 3 holidays (Christmas Eve, Christmas Day, and New Years Eve).
I would like to add time elapsed since an entry was made excluding weekends public holidays and calculating 8 hours a day (from 6am to 2 pm) since the entry was made till the generation of the report.
How shall I approach this in terms of programming ?
I am trying to limit the results of a SQL query by date. I would like to take the current date from the system clock, move back one day, check to make sure it's not a weekend or holiday, then use the result date to limit the results in my Query. If the current date minus one day happens to land on a weekend, the date picked should be the Friday before the weekend. If the current date minus one day lands on a holiday, it should be the date before the holiday as long as it is not a Saturday or Sunday (on another holiday) .
Here is my SQL query right now.
SELECT DISTINCT (Mid(ClientDiv.Client_Division,1,3)) AS ABC, RTIClientTracker.EMB_OOB, RTIClientTracker.OOB_Fixed FROM ClientDiv INNER JOIN RTIClientTracker ON ClientDiv.ID = RTIClientTracker.Client_Division WHERE (((RTIClientTracker.Division_Region)='RTI') AND ((RTIClientTracker.Cut)>=Date()-1)) ORDER BY (Mid(ClientDiv.Client_Division,1,3));
It limits what it selects by using the current Date minus one day.
I need to skip over Saturdays, Sundays and Holidays.
Currently I use a module to calculate DueDate, excluding weekends and holidays. I store all the holiday in a tblHoliday and reference this table in the module. A formula then calculated the DueDate. This works great in an access form, but I now realize that I need that value stored so it appears on the table as well, but do not know how to accomplish this.
I'm using access 2007 and have some date fields in my forms, i'd like to be able to blank out weekends and public holidays from the calender/date selector in these fields so theres no way those dates can be selected. Is this possible? Thanks.
I am using the function below to calculate a field that excludes weekends and holidays. The weekends are excluded as it is now, but when I try to add in code to exclude holidays I am getting errors. The code for the holidays is in bold and a couple of the errors are Loop without Do so I remove the Loop then I get a Else without If.
Code: Option Compare Database
Public Function WorkingDays(Due_Date As Date, Result_Date As Date) As Integer '-- Return the number of WorkingDays between Due_Date and Result_Date On Error GoTo err_workingDays
Let me just start out by saying that when it comes to Access, I ride on the "little bus", so I apologize in adavance if this is a lame question.
I have a table with two date/time fields. One for reporting the date and time of an issue start, the other for the date and time of an issue ending. I'm trying to find a way to get the number of hours between the two without including weekends. I found a module on mvps.org that excludes workdays. However it doesn't seem to work in this case. For instance, if I put in an issue start as 02/10/2006 7:30 am, and the issue end as 02/13/2006 6:45 am, it only counts it as one workday. It won't count the 13th as a workday until the time is >= 7:30 am.:confused:
I'm simply stumped. Any help would be greatly appreciated.
I have the below query (A). How do I calculate the Day of Therapy as shown in B
A MRN Last Name DOA Service startDate INR Dose WarfID VisitID 12001 Smith 6/28/2013 Warfarin 6/29/2013 1.20 6 mg 10 138 12001 Smith 6/28/2013 Warfarin 6/30/2013 1.20 6 mg 11 138 12001 Smith 6/28/2013 Warfarin 7/1/2013 1.3 6 mg 12 138 12001 Smith 6/28/2013 Warfarin 7/2/2013 1.40 6 mg 13 138 12001 Smith 6/28/2013 Warfarin 7/3/2013 1.40 7.5 mg 14 138 12001 Smith 6/28/2013 Warfarin 7/4/2013 1.70 7.5 mg 15 138 12001 Smith 6/28/2013 Warfarin 7/5/2013 2.00 7.5 mg 16 138 11002 Brown 7/1/2013 Warfarin 7/1/2013 1.00 2 mg 17 139 11002 Brown 7/1/2013 Warfarin 7/2/2013 1.3 4 mg 18 139 11002 Brown 7/1/2013 Warfarin 7/3/2013 1.50 2 mg 19 139 11002 Brown 7/1/2013 Warfarin 7/4/2013 1.8 2 mg 20 139 11002 Brown 7/1/2013 Warfarin 7/5/2013 2.20 2 mg 21 139 1205972 Jones 6/28/2013 Warfarin 7/6/2013 1.0 6.5 mg 29 138

What I really want is to calculate the time (# day) it takes to reach a target goal INR (2-3) I have tried DateDiff between DOA (date of admission) and Start date but this obvious won’t work because some patient won’t start on warfarin until later.
Another possibility is to calculate date difference between two rows in same column but I don’t know how For example Pt 1 = It take 7 days to reach an INR of 2, Patient #2 = it takes 5 days to reach an INR 2.2 and Patient #3 takes 6 days to reach an INR of 2.1. Average = 6 days.
I am trying to use a query to find the previous record of a transaction and provide an additional field that computes the difference in the dates in days. (The days from TransferID 23 to TransferID 24)
I have to create a query in access that will calculate two Date and time fields [Date & Time Left]/ [Date Returned], need to figure out between the two fields. Trying to identify when the rep returned the call and the number of business hours (6:00am - 4:30pm) it takes to return a message in Ms Access 2010.
The only issue is the calculation has to be done by time and so I have to calculate what time they left the message(so the difference between [Date & Time Left] and [Date Returned) [Date & Time Left] and when the rep returned the message which is suppose to be [Date Returned] but the problem with this field is the data entry is in date format (10/9/2014, 00/00/0000) of Date and not Date and Time like the [Date & Time Left] field, so I don't know what to do now. Not sure what to do now not a database that create or have allot of control over.
I'm using the Date()-1 to populate a form with yesterday's date for easier data entry. However, on Mondays I always have to change the date to Friday's date because it is populating yesterday's date (which in this case is Sunday). Is there an access expression that calculate yesterday's date but ignores weekends? So that on Monday yesterday would mean Friday?
I'm designing a query that must calculate a future date based on a recorded date. Unfortunately it's not as simple as just using adddate (unless I was using Excel!). Here's my requirements:
Future Date = [StartDate] + 45 business days
I am able to take weekends into account, but haven't been able to figure out how to bring holidays into the equation. I have an existing holidays table that I am using for another query within the database (calculates # of business days between 2 existing dates).
Hope this makes sense... I've been staring at it all day so I may not be thinking clearly anymore.
I have been looking for quite some time for some vba code that would return a date based on values in 2 fields.
In other words, I already have a field that returns transit days based on the customer chosen. End users will then enter a DueDate for the order. I want a field that returns a "ScheduledShipDate" based on [DueDate]-[TransitDays]. The part that makes this more difficult, in my opinion, is the fact that I also need to take into account some specific holidays.
I have already constructed a table with a list of the 6 company holidays and their corresponding dates. [tblHolidays.HolidayDate]
Unfortunately, my vba knowhow might as well be limited to copy and pasting as I do not need to use it all that often.
Hi all, I know this is a real easy one, but I am not the smartest when it comes to access. Can you help me out.
I am running a crosstab query to count and sum records in my database. I have a fied called "Amount". In my form the user is not always required to enter an amount. When I run the query, I would like the results to exclude the records that have a null value or $0.00 in the "Amount" field.
How do I format the query to exclude those records?
I want to know, by month, what the total extended price is for all customers. But some customers appear more than once in a month. So I also want to know the total extended price for the month, but I only want to include the extended price for each customer once, using only the record with the highest unit price (or extended price, qty for each customer is consistent), and ignoring additional records with the same customer in that month.
I am an excel user, and I could quickly do this with pivot tables... but I have too many records for Excel to handle this efficiently (it just keeps crashing!), so I thought I'd move to access... but I don't know how to use access! So I may need a little hand-holding here.
All using access 2010. I have a query1, query2 and query3. Query1 is my master. Query2 and Query3 was created based on different criteria but derived from the Query1. I now want to exclude the records from Query1 that are in Query2 and Query3. When I try to put isnull in criteria of both queries Im trying to exclude; instead of returning the remainder records in the master I get none.
I'm trying to figure out how many day are between now and a date on my form. I've done a search, but I can't find much that talks about DateDiff(). Here is what I have so far and it's not working. I'm typing this value into a text box on a form. =DateDiff(Day,Now(),"ASSIGNED_DATE_TIME") I want the interval to be in days. Thanks.
I'm trying to find the difference between 2 dates [Start_Date] and [End_Date], however I want to strip out out of hours work, which is [OOH_START] eg, 17:30 and [OOH_END], eg, 08:00. Also I need to strip out the weekends as well.
