Date Difference In Years, Months, Days

Jan 14, 2007

Hello,

I have two fields in a table, both containing dates. I would like to write a query that returns the difference between the dates in an year, month, day format (i.e. 26y 2m 3d). If that isnt possible, can the difference be returned as years,days (i.e. 26y 63d).

Thankyou.

Difference Between Two Dates Into Years Months Days

Aug 31, 2006

Hello to everybody.

I have a problem in calculating the difference between two dates and displaying the output into Years Months Weeks Days. My problem is that dividing the number of days by 30 and requesting an integer is not accurate enough. I have looked at Pat and Jons examples shown in these threads

http://www.access-programmers.co.uk/forums/showthread.php?t=67472

http://www.access-programmers.co.uk/forums/showthread.php?t=89051&highlight=calculating+number+months

which either method would suit me as the accurate answer is what I am after.

My problem is that not all of my records would have a start and end date. Therefore both examples would result in an error.

Can anyone please give a hint on how to perform the calculations on those fields which have dates recording the results but ignoring those fileds which do not have a start / end date.

I am having a bad day and I'm sure the answer is so easy that I am going to kick myself but having played around with the modules by limited knowledge is not enough.

Many thanks in advance

Ian

Years / Months / Days Question

Jun 5, 2006

I have a form that I'd like to place a date onto, after entering a from date and a to date. What I'd like to see on the form, after entering my two specified dates, is:

"You have xx years, yy months and zz day left on your timeline." where xx is the number of years, yy the number of months andzz the number of days.

If I entered dates of say, 01/01/01 for my from date and 12/31/06 as my to date, how can I accomplish something like what I want?

Thank you so much in advance! I'm looking forward to your suggestions!!!!

Queries :: Calculating Years / Months And Days

Aug 6, 2014

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.

Code is:

Code:
Months: IIf(IsNull([TIR]),0,IIf(Day([TIR])<=Day(Date()),DateDiff("m",[TIR],Date())-[Years]*12,DateDiff("m",[TIR],Date())-[Years]*12-1))

Modules & VBA :: Calculating X Years / X Months And X Days Between Two Dates

Jul 19, 2013

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

[code]....

Queries :: Date Criteria - Query Previous 12 Months Including Months With No Data

Mar 22, 2013

I currently have a form where users can enter an "End Date", click a button, and it queries the data from 12 months prior to "End Date" entered.

Is there a way to force the query to show all 12 months, even if there are no records for a particular month? For example: if the user enters February 2013 in the date field, I would like the query to return:

March 2012
April 2012
May 2012
June 2012
July 2012
August 2012
September 2012
October 2012
November 2012
December 2012
January 2013
February 2013

...so even if June 2012 has no records, it is included in the query with a value of zero.

This is what I have so far:

WHERE (((Qry_Tbl_Assets.Dte) Between DateAdd("m",-12,[Forms]![Main_screen]![End_Date]) And [Forms]![Main_screen]![End_Date]))

Queries :: Building A Query To Pick Between Set Months / Days But Different

May 4, 2014

I am building a database with Access 2013. The information contains data built from a workplace violence report form. I have to build a query to pick the data but must fall between two different years.The data range must be from 09/01 previous year (ex. 2012) and 08/31 current year (ex. 2013).

As the database collects more information, the year range will change but the other information will stay the same (ex 09/01/2013 to 08/31/2014).I do not want to change the query annually, just let it change the year automatically.

How To Scan For An Aniversary Date Without Using Years?

Dec 29, 2005

I have a table with these 2 fields: Name and AnniversaryDate. What is the best way to write a query that will show me all the anniversaries that will fall within the next two weeks?

For instance if I have a record with these values:

Name, Anniversary
BukHix, 1/1/2003

I want the query to look at today’s date, which in this case would be 12/29/2005 go two weeks forward, which would make it 1/12/2006 and show any anniversary date that would fall between the dates.

The catch (and the part that is throwing me off) is how do I do that without explicitly naming the year? I mean I need to catch every date in that range from 1965 to Current year - 1.

Any ideas?

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!

Problem With Harvesting Records By Date Spaning The Previous And Current Years

Mar 3, 2005

Im working on a make-table query that harvest records for calculation that span a "rolling" 13 week history... my problem is that the query will work if it doesn't have to retrieve work weeks that are prior to the new year. For example, right now is the tenth week of this year so i need to grab the previous 9 weeks of history plus 4 weeks of the prior year. then next week when the query is ran we will be in the 11th work week of the year therefor i will need to harvest the past 10 week plus 3 week of the preivious year. the query works if you don't have to span accross calendar years. here is the SQL of the query below the problem area is in underlined in bold type:
SELECT PORVPHIS.VENDOR_ID, PORVPHIS.VEND_NAME, [Expr2] AS [Fiscal Year], DatePart("yyyy",[DATE_RECV]) AS Expr2, DatePart("ww",[DATE_RECV]) AS Expr1, PORVPHIS.QTY_RECVD, PORVPHIS.PO_UNT_PRC, [PO_UNT_PRC]*[qty_recvd] AS [Total Price], [Expr1] AS [Fiscal Week], IIf([fiscal week]=[LowWeek] And [Expr3]<>0,[total price],0) AS 1, IIf([fiscal Week]=[LowWeek]+1 And [Expr3]<>0,[total price],0) AS 2, IIf([fiscal Week]=[LowWeek]+2 And [Expr3]<>0,[total price],0) AS 3, IIf([fiscal Week]=[LowWeek]+3 And [Expr3]<>0,[total price],0) AS 4, IIf([fiscal Week]=[LowWeek]+4 And [Expr3]<>0,[total price],0) AS 5, IIf([fiscal Week]=[LowWeek]+5 And [Expr3]<>0,[total price],0) AS 6, IIf([fiscal Week]=[LowWeek]+6 And [Expr3]<>0,[total price],0) AS 7, IIf([fiscal Week]=[LowWeek]+7 And [Expr3]<>0,[total price],0) AS 8, IIf([fiscal Week]=[LowWeek]+8 And [Expr3]<>0,[total price],0) AS 9, IIf([fiscal Week]=[LowWeek]+9 And [Expr3]<>0,[total price],0) AS 10, IIf([fiscal Week]=[LowWeek]+10 And [Expr3]<>0,[total price],0) AS 11, IIf([fiscal Week]=[LowWeek]+11 And [Expr3]<>0,[total price],0) AS 12, IIf([fiscal Week]=[LowWeek]+12 And [Expr3]<>0,[total price],0) AS 13, DatePart("ww",Now())-13 AS LowWeek, IIf([fiscal Week]>=[LowWeek] And [fiscal year]<>DatePart("yyyy",Now()),0,[LowWeek]) AS Expr3, [LowWeek] AS week1, [LowWeek]+1 AS week2, [LowWeek]+2 AS week3, [LowWeek]+3 AS week4, [LowWeek]+4 AS week5, [LowWeek]+5 AS week6, [LowWeek]+6 AS week7, [LowWeek]+7 AS week8, [LowWeek]+8 AS week9, [LowWeek]+9 AS week10, [LowWeek]+10 AS week11, [LowWeek]+11 AS week12, [LowWeek]+12 AS week13, PORVPHIS.DATE_RECV, IIf([Expr4]="AS8819" Or [Expr4]="CO1870" Or [Expr4]="GV2510" Or [Expr4]="MC3105",[VEND_NAME],Null) AS ID, PORVPHIS.VENDOR_ID AS Expr4 INTO Tporv
