Calculating A Date Six Months In Advance Of A Date

Jan 20, 2005

Not sure if this is actually done with a query (hell, im not sure if it can be done) as my Access knowledge is limited but I've got a list of Patient Appointment Dates and I need to calculate a list of 'Next Appointment' dates that are six months on from the appointment dates not including saturdays and sundays (as the health center is closed those days)

BTW this is for coursework, I don't really work for a health center :S

edit: I seem to have put this in the tables forum, not the queries forum. Apologies for that, I'm not an Idiot, Honest!

Calculating Date

Jul 17, 2006

I'm suppose to create a list of 20 clients and let 5 accounts be 90 days past due, 5 over 60 days, 5 over 30 days three of each of the accounts have a balance over $75. Then it asks me to create a total of all account balances so that the total amount of recievables can be known. The second part is calculate the number of days each balance has been outstanding.My question is this can you calculate dates in a table or can you only calculate in a query. I'm new at access so have patience with my question(s)

Calculating Age At A Particular Date

Aug 19, 2007

Please help me calculate the age of a person at a particular date without having to go into the expression every year and change the cutoff date year.

A basketball player in our league must be a certain age as of Sept. 30 each year to play in leagues divided by age. I am using the following to calculate age:

age: Int(DateDiff("d",[bdate],#9/30/2007#)/365)

I want to get rid of the 2007 and replace it with an expression that will automatically change every year.

Thank you for your time and consideration

Time Date Formatting For Calculating

May 15, 2006

Apologies if this has been asked before but I have a problem with being able to format a field to accept an hours and minutes value where the hours is likely to be greater than 23.

I have a form that is related to the number of hours that people spend in respite care. Entry and exit dates are provided in a standard way - date and time - and I have a calculating field that calculates the number of hours and minutes that a person spends at the respite centre based on the entries made in the entry and exit fields.

Because the calculating field is based on a module and I need to have the calculated amount included in the table, I have set up a VBA code to copy the result of the calculation into a controlled field elsewhere in the form.

However, I also need the form to do a simple calculation whereby hours spent away from the centre are subtracted from the total hours calculated by the module, so I need the copied value to be in a format where the calcualtion is able to be performed.

In a nutshell I guess I am looking for a time format for the field that will allow the recipt of a value greater than 23 hours.

Of course perhaps I need a more sophisticated VBA script to perform the calculation behind the scenes but I admit to not being particularly at ease with VBA scripting. If anybody has any suggestions about either a format or a suggestion for a VBA script, I would be very appreciative.

Thanks in advance,

Chris Montgomery

Calculating Dates Between To Date Ranges

Dec 27, 2007

Calculating dates between TWO date ranges:

I've read alot of good things on here regarding the DateDiff function and some other things that have helped me out finding the difference between two dates within the same entry on a table. I have a question regarding finding the difference in days between two entries within the same table.

Example:

test table:

Date ID # Name
1/18/07 1234567 Smith
1/20/07 1234567 Smith
1/23/07 1234567 Smith


Is there a way to find the difference in days between the lowest and highest dates? I want to know how many days are between the first entry and the last entry? In this cae it would be five days. I can do it if the days are in the same entry with the datediff function, but having trouble finding it in this situation. Any pointers?

(Thanks for all the good information on this site, BTW. I've seen a few posts similar to this, but it didn't really answer my question)

Queries :: Calculating Different Date Formats

Jul 18, 2014

I have a query based on two tables that calculates days elapsed between two dates. Problem is one date field is date/time and the other is short date, so the result is always infinite decimal places. I don't want to change the date format for the date/time on the one table. I tried the format function in the query, but still ended up with decimal places.I just want to make that one long date to act like a short date for calculating "days", not hours, etc.

The 3rd column is the one that will display how long is left to run! How do I achieve this?

Calculating New Date And Returning Dates Within A Range

May 26, 2005

I am tring to add a number of years to a dob. I'm doing this by adding my
date+years*365.26 I get a string of numbers. I then convert the number in
the next column to actual date again. I'm getting the correct date. I've tried unsuccesfully to use the dateadd function.Now I want my criteria on that column to allow me to return only date in a given to from period of my choosing. I want to determine the date range each time I run the query.

An example would be:

DOB age date I need to follow up
5/15/1935 + 75 = 5/15/2005

Then I request dates between 4/1/05 and 5/30/05 and this date is returned.


I've tried the between_and functions but nothing is returned. I'm guessing it's because the column is still a calculation and not a true date.

I've tried: Adding a column to my query to convert the number string back to
date format (criteria failed to return a result). Adding a second column
that ='s my converted number to date column (criteria failed to return a
result)
And I've tried the make table query and then run another query from the new table. I can't seemto make this happen. I think it's not recognizing my data as a date because it isn't returning any data.
Is ther an easier way to: Add a number of years to a date and have it return
a date and not the number string?
If not is there a better way to convert the string to a date?
Is there a way to get my criteria to recognize the date and return date
between my begin and end dates?

Thanks

Calculating Number Of Work Dates From 2 Date Fields

May 29, 2005

In my Query I have a Date Received field and a Date Approved field.

I would like to calculate the number of work days, which excludes weekends, between Date Received and Data Approved fields.

It would be more desirable to calculate the number of work days, excluding weekends and governmnet obsereved holidays.. but I don't know if that can be done... If not I can stick with the number of work days excluding weekends.

How would I go about doing this? I would need to add a new column to my query?

What would I put for the field and criteria? What kind of expression do I use?


Any help will be appreciated, thanks

Modules & VBA :: Calculating A Date While Taking Into Account Holidays

Mar 17, 2015

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.
