I have written a simple function to track payments, and as part of the function want to keep track of the last amount paid and the date the last payment was made within a single cell.
In order to do this, I used the formatDate formula so that the date entered via a date picker would appear in the DD/MM/YY format.
For some reason, the dates entered via the date picker are not working properly with the formatDate formula. For example the date 10/2/20 (10th Feb 2020) is being returned as 41/2/20 and 20/2/20 (20th Feb 2020) is being returned as 51/2/20.
Obviously, it seems like the formula is somehow adding 31 to the dates entered, but I would like some help understanding where I am going wrong.
Here is a picture of the code for my addPayment function:

It was suggested to that Utilities.formatDate() was not working with the format string of “DD/MM/YY” and I simply suggested to try “dd/MM/yy”

I am programmatically generating new form responses from rows of data in a Google Sheet (one approval workflow system generates new approval requests in a second approval workflow system). The data includes dates. My script takes the date value as a string from a cell, converts it into a native JavaScript date object, then submits this to a new form response using createResponse(). Here's the pertinent code:
var startDate = googleFormsDateStringToDate(eventDetails['Event Start Date']);
var r = item.createResponse(startDate);
For the most part, the system works robustly. Except for one intriguing problem - for any date after 29/04/2020, the date stored in the response is decremented by 1 day. Any date on or before this date works as expected, any date after is decremented by a day.
I have tried a few things.
The dates correspond to a start date and end date for an event. If the start date is before this date and the end date after, the end date will be decremented whilst the start date is recorded accurately. So I am certain the issue is directly related to whether the date I am submitting falls before or after this date.
I have tested extensively and am absolutely certain that the string-date conversion is working. If I retrieve the value of the response immediately after creating it (before the form response is even submitted), I find that it has been decremented:
var startDate = dateStringToDate(eventDetails['Event Start Date']);
Logger.log(startDate.toString()); // startDate is always accurate
var r = item.createResponse(startDate);
Logger.log(r.getResponse()); // if after 29/04/2020, will be decremented by 1 day
This tells me the issue is occurring precisely when I create the response and that it is occurring "at Google's end".
One of my suspicions is that it may be a timezone issue, but that would not explain why the issue is linked directly to this specific date. My other suspicion is that it may be to do with the fact that 2020 is a leap year, so we get 29/02/2020, and the date after which the error occurs is 29/03/2020. Perhaps somewhere behind Google's implementation of createResponse it is failing to account for the leap year?
Until I can identify the error, I plan to implement a workaround in which I will use getResponse() to check if the response date matches the intended date and correct accordingly. But I would prefer to understand what is causing the error (so I know if it is a bug requiring reporting, or simply my lack of understanding) and, if possible, find a solution.
So, specific questions: What is the source of the error? Is there a solution (rather than a workaround)?
EDIT
Whilst figuring out a workaround, I have answered my first question. In the UK, daylight savings time starts on 29/04/2020. Since the dates entered via the Google Form have no time associated with them, the time appears to be stored as 00:00:00, or midnight. I assume that what is happening is that the adjustment for daylight savings time (1 hour) is subtracting an hour from this time, thereby rolling it back to the day before.
My final question stands: is there a means to reliably prevent this error from occurring rather than manually checking for inaccurate dates (or programming in daylight savings time dates)?
Im having problems with this.
I have this qlikview script which is run on the 15th of every month. This script intends to automatically take the last date of the previous month in the format of 'YYYY-MM-DD'.
For example today is 15th January 2017. I will run my script and it will give me a date of 31th December 2016 in the format 2016-12-31.
If it is 15th December 2016, I will get 30th November 2016 in the format 2016-11-30.
I want to set the date retrieved as a variable in the format yyyy-mm-dd to be used in another query.
Basically I tried
SET #vLastDate = DATE_FORMAT(select last_day(curdate() - INTERVAL 1 MONTH), '%Y-%m-%d');
but I receive an error that it does not execute. I am doing this in qlikview. Please help me identify my problem thank you.
You are trying to execute mysql functions in qlikview? That won't work.
Try in QV script:
let vLastDate = MonthEnd(AddMonths(Today(),-1));
If you need to change the date format, play around with the Date#() function, probably something like Date#(Field, 'YYYY-MM-DD'). Today() returns YYYY-MM-DD format so it will probably be fine.
What is the correct function to use when i want to convert a date to a number. Like when you enter a date in excel for example (now()) and then it will show the date but when you click on the number format it will show you a number.
I tried to use Unix timestamp but its not exactly the output i was looking for.
The date i entered is today's date
=now()
and the output i was hoping to get is
42146
what's the correct function to get this result in mysql?
Thank you
Microsoft Excel bases date serial numbers from Jan 1, 1904 or from Jan 1, 1900 (depends on the setting in the workbook.)
To generate a date "serial number" similar to what Excel uses, just calculate the number of days between NOW() (or whatever date you want to convert), and the base date. For example:
SELECT DATEDIFF(NOW(),'1900-01-01') AS excel_serial_date_1900
(You might need to add 1 or subtract 1 to get the exact same value that Excel uses, I've not tested that.) If your Excel workbook is using the 1904 based serial date, use '1904-01-01' as the base date in the expression.
Note: the DATEDIFF function returns integer number of days, operates only on the "date" portion, and doesn't include any fraction of a day.

i'm trying to specify dd/mm/yyyy dateformat for date/time parameter in SSRS 2008 R2.
My computers datetime format is mm-dd-yyyy.
My requirement is, i want to show date format at dd/mm/yyyy irrespective of the system/server date format.
I've already tried CDate(Format(Today,"dd/mm/yyyy")) which didn't work. one very strange thing i observed is, it shows dd/mm/yyyy format only for dates on or before 12-MM-yyyy, and 13 onwards it gives error: Conversion from string '25-04-2014' to type Date is not valid. (Possibly it is trying to map 25(daypart) with MM-dd-yyyy (month part)) which is out of range of total months i.e. 12)
my research on internet says it is a bug in BIDS 2008.
What do i do to display date as dd/mm/yyyy ??
I don't have enough reputation to comment, but I did notice that you failed to put "()" after "Today". If I'm not mistaken you must put Today() for that function to work. Also, you might want to try putting CDate Around the Today() function. You shouldn't need it, but it's worth a shot. Also, for some odd reason, in my experience, you must capitalize MM for format to work correctly.
Like #Aditaya said, it should be =format(Today(),"dd/MM/yyyy")
The expression I usually use is:
=FormatDateTime(Fields!Date.Value, DateFormat.ShortDate)
However, this may be region specific.
Rather than writing an expression to do the formatting, you can also use the Textbox Format Property. But first you need to make sure that the data is in a date format. So use the CDate function on your column like this:
=CDate(Fields!Date.Value)
Then in the textbox properties go to the Number tab. Select Date for the category. Then you can select whichever format you want or use a Custom format. This will change how the column displays when you run the report.
I need current month name as default perameter name in my ssrs report. How can I get current month name using an ssrs expression?
For example "27-09-2012" would become "September"
and one more i need....
27-09-2012 to previous month name as well (August)
First question:
=MonthName(Month(Fields!datefield.Value))
Second question:
=MonthName(Month(DateAdd("m", -1, Today())))
I think the second question answer might be something like that, first converting the date to month then subtracting 1 from the month value and then converting it to month name.
Further reading:
SSRS Reports get Month name from Month Index or from date

OFF: I would change the date format you are using to 2012-09-27 as it works in every setting and should give you peace of mind when converting date formats.
Don't subtract 1 b/c it won't work for January.
Use this:
MonthName(Month(DateAdd("m", -1, CDate(Today))))
As a note, I tried the suggestion of =MonthName(Month(today())). What I would get is #error for whatever field the expression was in. However, =MonthName(str(Month(today()))) worked for me. I am unsure of whether or not the MonthName method changed to require a string or if it is some issue with my program. Just figured I would post this in case anyone else was having the same issue.
For Previous Month i found universal way : =MonthName(Month(CDate(Today()))-1,False) for SEPTEMBER (Full Month Name) 'OR'
=MonthName(Month(CDate(Today()))-1,True) for SEP (Short Month Name)
