Todays date is 31.03.2011 (European, at least).
A hotel room is booked from, lets say, 23.02.2011 to 05.05.2013 (yes, over two years!).
How can I check if todays date is in between the reserved dates or not?
Ideally I want to sort it into an boolean array of 3 dimensions, like date(year,month,day) and TRUE means "booked".
Preferred language is VBScript because this is my only option, but Java/C whatever is also okay to use as an example to work from (text explaining the solution is of course also okay).
Thank you!
Don;t know VBScript but the time/date library can normally return times in an integer format (typically seconds since 1970). Just convert the three dates to this format and check using the normal compare operators
VBScript Functions notes a Datedifffunction that you could use with the 3 variables representing each point in time. Course there are other solutions to this like converting the date to another type and using that for comparison,e.g. concatenate yyyyMMdd into an integer and compare them that way.
checkIn=DateSerial(2011,02,23)
checkOut=DateSerial(2013,05,05)
testMe=Now
If testMe>checkIn And testMe<checkOut Then
MsgBox("Living the good life.")
End If

My boss asked me to add a double slider input control for the date information on a report on Webi.
We have several columns and two of them display a date (start and end date of procedure). So I need to have two double slider, one for each date.
I've been searching for a whole day now and I know that it is not directly possible to use double slider with dates, because double slider only works with values (measures) and dates don't have that.
But I managed to create two more variables on the business layer. I used the following SQL function:
CAST(currentDate as Bigint))
These variables are displaying the date as numbers (e.g. 1090101 for 01.01.2009 (format is "dd-MM-yyyy")).
And it is working great! But it displays the dates as number, which is not possible to use for work. No one will know which date is 1090101. I could perhaps let both columns (date as date and date as number) in the report, so people could check the date they want to filter with the input control and select the right number on the slider. This could be a workaround, but not a clean one, I think.
I tried to change the format of the date as number to a date format, but then I could not use the slider anymore (even if the variable is a number).
I looked for a way to change the formatting of the values displayed on the slider, but with no luck.
So I'm asking for your help. Does anyone know how I could make this work?
Is there really no solutions for such a useful way of filtering data? I mean, filtering data by an interval of dates is surely something people want to do quite often, I assume.
Thank you in advance for your time.

You could format your date value as year, month, day and then convert it to a number so the value you are filtering on makes a little more sense. Like this...
=ToNumber(FormatDate([Your Date];"yyyyMMdd"))
It will be better than just an arbitrary number, but certainly not perfect since you will have large chunks of your range for which there never will be any corresponding data (e.g. 20211232 through 20220100).
What is wrong with just a Minimum and Maximum input controls? They are more intuitive and simple to create. Sometimes what your user or boss asks for is a bad idea and/or just not possible.
I am using cognos version 10 and I need my dates to display in this format 'yyyy-mm' but it is showing dates like '2014-04' as '2014-4' so it is reading the dates out of order by producing '2014-11' first because it starts with a one. I need to add a zero to those double digit integers that way the months(specifically) will display in order.
here's an the code I've created in attempt:
_year( start_date ) ||'-'|| _month( start_date )
IF(_month(start_date) > 10)
THEN('0' +_month(start_date))
Short answer: Use yyyy-MM.
Your question lacks a lot of detail, so my response is based on considerable guess-work.
Are you asking about formatting, or do you want to transform the values? Formatting can be done without code. The code for your data item should be start_date.
Is this for a List column body? Where do you enter your format (yyyy-mm)? Are you using the Data format property?
In the Data format dialog, if you can't find another setting that will do what you want, you can enter a pattern into the Pattern property. If you look at the tips at the bottom of the Data format dialog, you'll notice that using yyyy-mm would give you a four digit year, a hyphen, and a two-digit minute. Perhaps you should try yyyy-MM. It works for me.
As for sorting: Even if you used yyyy-M for the pattern, 2014-04-22 (displayed as 2014-4), should sort before 2014-11-01 (displayed as 2014-11). The only reason the sort would be wrong is if it is using some other data besides the dates.
We have a vendor which one field in the database is a number and somehow in the app interface it shows the date,
I'm trying to figure out how is this conversion
Here is the data:
this number 15862 generates this date 06/05/2013
I have no idea how, the vendor told us it is NOT a custom logic conversion it was used a tsql function although I can't figure which one.
I tried using "convert" without success.
I don't think that's from a tsql function considering it's derived using the UNIX time epoch. Basically it's number of days since 1969-12-31
But you could get it using tsql like so:
select datediff(d,'1969-12-31','2013-06-05')
It looks like it's using a base-date of 1/1/1970 (actually 12/31/1969) and the number represents the number of days after that.
Most probably this is saved as an offset in days since 01/01/1979:
date('m/d/Y', 15862*3600*24) gives 06/06/2013 and
date('m/d/Y', 15862*3600*24-(3600*24) gives exactly 06/05/2013
I've found several questions regarding SAS dates in this forum, but i haven't been able to find the answer to this one. I think it is rather simple, but i can't get it right.
I have a data set with a date (DD-MM-YYYY) which for some reason has a Character format. I would like it to be translated into a date format (YYYY-MM-DD). I can get it to 'look' right by by separating and concatenating the parts, but, then i can't get the format right.
Use the input() function with an appropriate informat:
datevariable=input(textvariable,ddmmyy10.);
I am using Objective-C within X-code.
I am iterating through a dictionary which contains a date value as one of it's keys. All I want to do is get an array of all the distinct dates so I can use them in a table, as headers. I just plan on
iterating the dictionary and adding dates to a mutable array each time I encounter a new date.
I must set previous date to new date for comparisons to work and I am having a very difficult time figuring out how to set one date equal to another date.
This seems like it should be such a simple thing to do and I am trying to avoid converting the dates to strings first - but if that's what I have to do, then so be it.
Any help would be appreciated.
Thanks,
Gerry O.
If you know the time offset is same as GMT, you could do it by dividing the date's timestamp by 86400 seconds (or three more 0s in milliseconds) and comparing those. If a time offset is there, add or subtract by 3600 seconds per hour before you divide them. But then again, leap years and seconds would break that...
Most languages have libraries support extracting the year, date, month, etc. They take everything into account, usually.
In Objc, you can get a NSDateComponents from NSCalendar's components:fromDate: method. After this, you can call the components to see exactly what each component (I suggest year, month, day) is.
I think you want code to compare dates and You need two loops nested.... where in outer loops iterates with conditional inner loop... In inner loop you just check that previously you had the same date or not...
please go through the below post on same site...

hope you will get solution... else clarify your question....
