calculate difference in dates

Hi,
I need to calculate difference in Start_Date
& End_date in output format like 'x Days y Hrs and z Mins'.

The Strat_Date & End_Date have format like HYYMDs.

I am able to find difference for 'x Days and y Hrs' but not for calculating 'Mins'. I am getting mins like 500 ,535 etc. Ideally it should be 20 mins etc(only 2 digits).
I am using HDIFF() function for that.

e.g.result/D6 = HDIFF(end_date,start_date,'MINUTE','D6') ;

Please suggest.

Take the result of your difference in minutes and apply basic maths to work out how many days, hours and minutes.

Thnx for ur reply Tony!

I did the same and divided the mins by 60.
e.g. 535\60 = 5.883333

I will get 5 hrs...but how do i pull the mins(using which func?)

Please suggest.

Your code looks correct. Please check your data. In the sample above, I get 5 minutes which is the answer I was expecting.

BB,

You just have to think about the basic maths behind your request.

You have minutes.
Hours is the integer of minutes / 60 as you have it, but first you need to do days? So .....

Days is the integer of minutes divided by minutes in a day - there are 60 minutes and 24 hours so your maths would be .......

Once you have the days, take the number of minutes in that number of days away from your minutes total to give you the number of minutes remaining.

Now work out the hours and again get the remainder, that becomes the minutes.

Simple, if you only think about it.

Using Ginny's code as a basis

DEFINE FILE CAR
BEGDTA/A20='20080910103000000';
ENDDTA/A20='20080911135500000';
BEGDT/HYYMDS=HINPUT(14,BEGDTA,8,'HYYMDS');
ENDDT/HYYMDS=HINPUT(14,ENDDTA,8,'HYYMDS');
DIFF_MIN/D6=HDIFF(ENDDT,BEGDT,'MINUTE','D6');
DAYS/D2=INT(DIFF_MIN/1440);
HOURS/D2=INT((IMOD(DIFF_MIN, 1440, 'D20.2')/60));
MINS/D2=DIFF_MIN - (DAYS * 1440) - (HOURS * 60);
DAYT/A6= IF DAYS EQ 1 THEN ' Day ' ELSE ' Days ';
HRT/A7= IF HOURS EQ 1 Then ' Hour ' ELSE ' Hours ';
MINT/A8= IF MINS EQ 1 THEN ' Minute ' ELSE ' Minutes';
DIFFERENCE/A30= TRIM('L', EDIT(DAYS), 2, '0', 1, 'A2') | DAYT |
TRIM('L', EDIT(HOURS), 2, '0', 1, 'A2') | ' Hours ' |
TRIM('L', EDIT(MINS), 2, '0', 1, 'A2') | ' Minutes';
END
TABLE FILE CAR
PRINT BEGDTA BEGDT ENDDTA ENDDT DIFFERENCE
BY COUNTRY
END
If you want leading zero's just use a plain edit and remove trhe TRIM
