Calculate Date/Time Difference in a Calculated Column Omitting Weekends, Holidays and Non-Working Hours

I am looking for a formula to use in a calculated column that calculates the difference between two date/time fields while excluding weekends, holidays and non-working hours
6/1/2010 9:43 AM - 6/7/2010 1:45 PM
Here is the closest that I have gotten; however, this formula gives me a result of 96:
=IF(AND((WEEKDAY([Resolved Date],2))<(WEEKDAY(Created,2)),((WEEKDAY(Created,2))-(WEEKDAY([Resolved Date],2)))>1),(((DATEDIF(Created,[Resolved Date],"D")))-(FLOOR((DATEDIF(Created,[Resolved Date],"D")+1)/7,1))-3),(((DATEDIF(Created,[Resolved Date],"D")))-(FLOOR((DATEDIF(Created,[Resolved
Date],"D")+1)/7,1)*2))*24)
Any and all assistance is greatly appreciated!

I don't know how to exclude holidays but i exclude weekends(Sat&Sun)-
IF(ISERROR(DATEDIF([Start Date],[End Date],”d”)),””,(DATEDIF([Start Date],[End Date],”d”))+1-INT(DATEDIF([Start Date],[End Date],”d”)/7)*2-IF((WEEKDAY([End Date])-WEEKDAY([Start
Date]))<0,2,0)-IF(OR(AND(WEEKDAY([End Date])=7,WEEKDAY([Start Date])=7),AND(WEEKDAY([End Date])=1,WEEKDAY([Start Date])=1)),1,0)-IF(AND(WEEKDAY([Start Date])=1,(WEEKDAY([End Date])-WEEKDAY([Start Date]))>0),1,0)-IF(AND(NOT(WEEKDAY([Start Date])=7),WEEKDAY([End
Date])=7),1,0))
-Thanks

Time Passage Calculation excluding Weekends and Non-work hours

Good Afternoon Everyone!
I am currently using the expression below to determine the amount of time that has passed since a Task has been created.
TIMESTAMPDIFF(SQL_TSI_MINUTE, Activity."Created Date", NOW())
We have a completion goal for a specific task type of 2 hours (120 minutes), but it should only be calculated minutes between 7 AM and 4 PM and only on week days.
So, a task created at 3:50 PM on a Friday that is completed at 7:30 AM on the following Monday should only calculate to 40 minutes of time.
I am at a loss for where to start tackling this problem. If any of you can help I would be very appreciative!

Hey Paul, thanks for the prompt. I see now that the formula is incomplete.
As I have just taken the difference in days between the Activity Start Time and End Time, it will consider any weekend. But its incomplete as it considers only 15 hours of a day and not the remaining 9 hours for weekends. For holidays - we do need a field or something to identify it like Activity Type = 'holiday'.
So the ELSE* part of revised formula would be something like this:
... ELSE TIMESTAMPDIFF(SQL_TSI_MIN,activity start time,activity end time) - (60*15*(DAY(Activity End Time) - DAY(Activity Start Time))) - (60*9*(COUNT(DISTINCT CASE WHEN DAYOFWEEEK(Date.Date) IN (6,7) OR ~some field to identify holiday~ = 'something' THEN 1 END)) END
now imagine there's one activity that started on Friday 7:00 AM and ends on coming Monday at 4:00 PM.
Actual duration is 18 hours.
Now,the first term after ELSE will give 81*60 minutes. next term should give 45*60 minutes. third term would be 18*60 min.
so the entire expression would return 18 hours.
Even if there's a holiday, then i guess the 'OR' part should capture it.
I hope this makes sense. Please let me know if it should need any further corrections.

Date & time difference in a single column but multiple rows in a table

hi folks,
am using Oracle db 10g by chance is there any other way to do my requirement.
as I stated in my subject.

You probably need LAG:

dual union
3 select 200, 36,to_date('28.05.2012 15:00:00', 'dd.mm.yyyy hh24:mi:ss') from dual
4 )
5 --
6 -- actual query:
7 --
8 select bno
9 ,      temperature
10 ,      dt
11 ,      numtodsinterval(dt-lag(dt) over (partition by bno order by dt), 'day') difference_int
12 ,      substr((numtodsinterval(dt-lag(dt) over (partition by bno order by dt), 'day')), 12, 8)
difference_dt
13 from   testdata;

2 rows selected.But, as Paulie already said: still insufficient input. We know nothing about your datatypes. I assumed you're using a DATE.

Thanks

you can use beans or create a case when statement like:
case
when TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) <= 60 then 1 else
when TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) > 60 and TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) <= 90 then 1.5 else
when TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) > 90 and TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) <= 150 then 2.5 else
end

How to measure time difference between zero crossing of a sine wave and rise time of a pulse on a same graph?

I have a 50Hz sine wave and a pulse signal on a same graph. The phase difference between two is between 0-90 degrees.
Now I need to calculate the time difference between (when the sine wave crosses zero volts) and (when the pulse rises). The frequency will stay approximately same for both signals.
The application is for a three phase generator. In simple words, when the time difference between the zero-crossing of sine wave and the pulse rises increases, that means that the load on the generator has increases.
I am a beginner user of LabView (version 9, 2009), maybe it is a very simple problem but I've been pulling my hair out for the last few days and coudln't figure anything out. Any help would be greatly appreciated. I am using DAQ USB-6008 to measure these voltages and pulse from the generator and a sensor
I have attached a jpg (a graph that i just made with excel to explain). The time 't' is what I am trying to measure
Cheers

Solved!
Go to Solution.

Hi
Thanks for the code but I'm afraid it won't work. Like you said the probability of choosing a value that is on both graphs may not happen. This is something that I would like the code to do automatically.
But I did use the previous code posted and made some modifications to it and it seems to work perfectly. Now the next thing is to be able to get just that one value that tells you the first time difference.
Here is what I get using that code.
As you can see from the t Values. I only need the one that is highlighted. If there is a way to filter out the rest it would be great.
I was thinking of a while loop and as soon as the value is higher than 3E-5 it would store the number and stop the loop, but I'm not too familiar with arrays in labview.
Here is the the code modified.
As you can see, it wasn't that big of a modification and it still is your code.
I will keep trying.
Thanks for the help

This sounds like an error in Time Zone support. The time zone needs to be the same in Outlook as well as the phone.

Date/Time difference based on working days

Hi Guru's,
I am having a problem getting the difference between two timestamps. A normal difference between 2 timestamps is possible however i would like to calculate the hour difference between 2 timestamps excluding public holidays, weekends and also after office hours. Is there a series of FM or a logic to extract this kind of info. Hope you guys can shed some light into the matter.
Thanks in advance.

Hi,
Use FM DATE_COMPUTE_DAY. DATE in MM/DD/YYYY format.
This FM returns the date in form of weekday number ie the date which you give is tuesday then it will return 2.
Give call log date and call handled date.
eg A call is logded on tuesday 3.00 pm and handled on Thursday 10.a.m.
First check the days difference from the return of this FM.
IF the call handled date return - call loged date return is positive means no sat sun , if negative means sat and sun.
then from call logged date time start counting the office hours till call handled time.
Office hours can be easily calculated using 24 hours clock.
For public holidays have to check whether between the twodates any public holiday if is there then subtract that much office hours.
Hope this helps.
Thanks,
Niketa

How to calculate the time duration on a datetime column?

Hi guys,
I've done some search on this forum and everywhere else but I can't seem to get this right, at the beggining it sounded like something very simple to accomplish, for the instance with Excel but I'm struggling to get it to work with Crystal Reports on Microsoft Visual Studio 2008.
I have a datetime column (SQL Server 2000) that I wanted to calculate the the time duration on the report group footer, unfortunatelly the built-in SUM function cannot be applied and I've tried several formulas that I've found on the internet without any luck. I'm using a datetime column to store only the time because I'm stuck with SQL Server 2000 which doesn't have a time data type.
Would you guys know how to do it by any chance?
Some sample code I've tried: http://www.minisolve.com/TipsAddUpTime.htm
Thanks a lot,
Paul

Guess what, by further testing the code on the website mentioned above I got it working.
Pus, I needed to change the grouping on the code, so I had to come up with a way to update the formulas based on the groupping field.
Considering "call_date" is the field that you are groupping by on the designer use the following code to update the formula:
CrystalReportObj = new ReportDocument();
CrystalReportObj.Load("C:\\reportfile.rpt");
FieldDefinition FieldDef;
//Get formula
FormulaFieldDefinition FormulaDef1;
FormulaDef1 = CrystalReportObj.DataDefinition.FormulaFields["SubHours"];
//Get formula
FormulaFieldDefinition FormulaDef2;
FormulaDef2 = CrystalReportObj.DataDefinition.FormulaFields["subMinSec"];
//Update the formula to work with the new grouping field,
//this must be called first else will throw an exception
FormulaDef1.Text = FormulaDef1.Text.Replace("call_date", "call_extension");
FormulaDef2.Text = FormulaDef2.Text.Replace("call_date", "call_extension");
//Get the new field we are grouping by
FieldDef = CrystalReportObj.Database.Tables[0].Fields["call_extension"];
//Replace current grouping field with the new one,
//considering there only one group in the report, index 0
CrystalReportObj.DataDefinition.Groups[0].ConditionField = FieldDef;
Have fun.

Function Module for Date/ Time difference in Working Days

Hi all,
Are there any function modules which will calculate the difference between a date AND time, but in working days?
I can use the FIMA_DAYS_BETWEEN_TWO_DATES_2 FM for the dates, but I need to include times in this as well.
This is for situations where the 'starting date' is a non-working day, and the 'end date' is a working day. In this situation I need to take all the hours and minutes into account, which happened on the working day. To give an example -
Start date: 04.07.2010 (Sunday - Non working day)
Start time: 21:12:36
End date: 05.07.2010 (Monday - Working day)
End time: 04:47:24
I realise there is a Time option in this function module, but when I test it, it doesn't seem to be returning the desired results (returns 0 for days and time). I am using '5' as the I_STGMETH and 'GB' as the I_SKALID.
I need a calcuation which will return the time, post midnight on the working day - in this example, 4 hours, 47 minutes (seconds are optional!).
Can anyone help? - can I still use FIMA_DAYS_BETWEEN_TWO_DATES_2 but with different parameters?
Thanks
Mischa

Hi,
Thanks but this FM does not seem to account for working days.
For example, if I use:
DATE1                           04.07.2010 (non working day)
TIME1                           04:00:00
DATE2                           05.07.2010   (working day)
TIME2                           21:00:00
It will give the following results -
DATEDIFF                                                      1
TIMEDIFF                                                     17
EARLIEST                        1
I don't want to account for the non-working day so the result I actually want would be to calculate from midnight on 05.07 to 21:00 on 05.07 which should be 21 hours.
I suspect I probably need to include the STGMETH and the factory calendar somewhere in the FM?
Does such a FM exist, or could anyone help me with some ABAP for this?
thanks
Mischa

Help with calculated column formula- combine strings and convert to date

In my list (SharePoint Server 2013) I have:
'Invoiced Month' column, type of choice (strings with names of months- January, February, March..., December)
'Year' column, single line of text (e.g. 2012, 2013, 2014)
1. I need to create a calculated column which will return combined value of the columns above, but in DATE format e.g. 'Sep-2013' or '01-Sep-2013'.
I then use that newly created calculated column to do this: http://iwillsharemypoint.blogspot.in/2012/03/sharepoint-list-view-of-current-month.html
I am rubbish with formulas, can I have some help with my problem please?

Hi,
Use the formula, I have tested by creating Months column with choice, Year column as numeric and Calculated column as DateTime returned.
=DATE(Year,IF([Months]="January", 1,IF([Months]="February",2,IF([Months]="March",3,IF([Months]="April",4,IF([Months]="May",5,IF([Months]="June",6,IF([Months]="July",7,IF([Months]="August",8,IF([Months]="September",9,IF([Months]="October",10,IF([Months]="November",11,12))))))))))),1)
Before applying the formula few things need to be noted.
DATE(YEAR, MONTH,DAY) will accepts three parameters all should be type numeric(integer).
Create the Year column of type numeric
Create the calculated column of type "DateTime" to return as date
Please mark it answered, if your problem resolved or helpful.

Calculate Date/Time based on TimeZone

Hi guys,
what i want to do is the following:
given a database table tzdata composed of time zone names and tz offset
like this :
tzName tzOffset summer time used
Afghanistan ,+4.5, no
Albania ,+1, yes
Algeria, +1, yes
American Samoa,-11, no
i want to be able to display the corresponding Date / Time of each country based on the time zone offset .
I'm using a SimpleDateFormat , and want to know how to calulate time for each entry in table above.
thanks for helping !

given a database table tzdata composed of time zone names and tz offset
i want to be able to display the corresponding Date / Time of each country
based on the time zone offset .
in the offsets i posted above i found things like +10.5 ,-1.2 ect..
how to convert those into the correct format so i can feed it to SimpleTimeZone() construtor ?Why would you want to?
I am just pointing out here that java already has all those timezones and offsets configured into it. As well as if/when DST applies.
String[] zones = TimeZone.getAvailableIDs();
for (int i=0; i<zones.length; i++){
System.out.println("Zone " + i + " = " + zones[i] + " offset = " + TimeZone.getTimeZone(zones).getRawOffset());
In other words this database table is reinventing the wheel.
You just need to tell Java which Timezone you want (according to the standard names for timezones begin Region/City) and it will work out the correct offset.
eg
for Afghanistan: new TimeZone("Asia/Kabul");
Albania: new TimeZone("Europe/Tirane");
