No of weeks in a year

hi experts,
i want to calculate the no of weeks in any year entered by user .But the week calculation is the the form of technical weeks(TW).
1) Technical week starts from monday or first day of the month
2) Technical week ends on sunday or last day of the month
example For year 2007
From      |                   To           |              Technical_week      | ActualWeek

08/01/2007       | 14/01/2007       |                2TW        |            2
15/01/2007       | 21/01/2007        |              3TW          |            3

LIKE wise TW will be more than actual weeks in year 2007...
So in 2007 there are 52 actual weeks and 63 TW...
I want to calculate TWs for ANY year given by user on selection screen....
is there any function module for this... or can we create it... Need some logic
thanks in advance

How to get week of a year in American Standard

Hi,
I know it might be a repetitive question, but did not find a convincing solution to it in any of the previous threads. I am looking for a function (user defined, if someone has already written it) to return me the week of the year, in American Standard. i.e,the week should start on Sunday and end on Saturday (and NOT from Monday to Sunday)
01/03/2010 - Should be the start of 1st week of 2010...... 01/10/2010 will be the start of second week and so on
01/04/2009 - Should be the start of 1st week of 2009...... 01/11/2009 will be the start of second week and so on.
Does any one have a function that takes a date as input and returns back the week of the year in this above format? Any help is greatly appreciated.
Thanks

It's a bit trickier because the ISO rule has some fine prints.
Take a look at the example below:
SQL> with t as (
2 select to_date('01/02/2010', 'MM/DD/YYYY') dt from dual union all
3 select to_date('01/03/2010', 'MM/DD/YYYY') dt from dual union all
4 select to_date('01/03/2009', 'MM/DD/YYYY') dt from dual union all
5 select to_date('01/04/2009', 'MM/DD/YYYY') from dual)
6 --
7 select dt,
8         to_char(dt+1, 'iw') tweaked_week,
9         to_char(dt, 'ww') nls_week
10    from t
11   order by dt;
DT          TWEAKED_WEEK NLS_WEEK
3/1/2009    01           01
4/1/2009    02           01
2/1/2010    53           01
3/1/2010    01           01
SQL> If may notice that 02/01/2010 is week 53 and and that at the same time 03/01/2009 is already week 1, being 04/01/2009 week 2.
The reason is in the docs:
An ISO week always starts on a Monday and ends on a Sunday.
* If January 1 falls on a Friday, Saturday, or Sunday, then the ISO week that includes January 1 is the last week of the previous year, because most of the days in the week belong to the previous year.
* If January 1 falls on a Monday, Tuesday, Wednesday, or Thursday, then the ISO week is the first week of the new year, because most of the days in the week belong to the new year.It depends on what your requirement asks.
If you need to prevent any January 1st that fall on Monday to Thursday from becoming your week 1 you'd probably have to adjust that implementation and fine tune it further.
Let us know if that will do or what your rule would be otherwise.

do you mean, there were 53 weeks in that year? because I have concern, how it is actually counted...
wasn't bad... :)
Thats sounds Sweet
do you mean, there were 53 weeks in that year?
Yes
because I have concern, how it is actually counted...
If in a leap year fabruary falls in 5 weeks then that is the only possibility for 53 weeks
Cheers
PS:But No logic would be applied in this case

How to display the week of the year in a report

Hi,
I am doing a report, that needs to break down the information, according to month and then week.
The week of the year isn't stored anywhere in the database, so i guess it would have to be calculated.
How would i go about doing this in report?

hi, yes thats what i mean.
So if i run my report for 01-feb-2008 to 30-march-2008
it needs to group the data according to weeks.
eg. week5 (data)
week6 (data)
etc....
i got this code: select to_char(sysdate, 'IW') from dual;
will it allow me to do this?

FM for week in a year

is there any FM for
how many weeks in a year and
how to find the whether the year is leap year or not? and
how many weeks are in the month ?
i want the FM

Hi there. You can use function module hr_99s_interval_between_dates. Just pass a begin date and an end date, and then you can get the number of days, weeks, months, or years between the two dates. So you can pass the begin date and end date of a month to get the number of weeks in the month, or the begin date and end date of a year to get the number of days and weeks in the year. If the number of days is 366 then it is a leap year. I hope this helps.

Want to create analysis for this year week vs last year week

All,
My requirement is to create an analysis for the passed week number of this year vs same last year week no.
So basically user will pass the week no. and report should display the passed week no. this year sales number plus same week no. last year sales number.
How can I achieve this?
Thanks

If you ask like this ..I would say like using presentation variable for week
use measure with exp like
CASE WHEN WEEK=@{WK} AND Time.year=VALUEOF("PREVIOUS_YEAR") THEN #sales END.
In this case week is from your subject area and PREVIOUS_YEAR is rep variable you might have it.
there are other options to get output, need details about your rpd and value of week.

Fm - how many weeks in a year

is there any FM for
how many weeks in a year and
how to find the whether the year is leap year or not? and
how many weeks are in the month ?
i want the FM

Hi Priya,
There is a function module 'TIME_GET_LAST_WEEK'.
In this FM, export the Year & you will get(Import) a value in a parameter
EF_WEEK. This will be the Concatenated String of Year&Number_of_weeks in that year
For Example If you run this FM for the Year 2004, the Parameter EF_WEEK will
be '200453'. That means last two digits gives the number of weeks in that year.
From this value you can easily get number of weeks (i.e,EF_WEEK+4(2)).
If this value is 53, then it is a leap year, else not a leap year

Determining current week of a year

Hi,
is anybody have idea, how to determine the current week of a year.
Please give some ideas.
Thanks

something like
Calendar cal = new GregorianCalendar();
int weeks = cal.get(Calendar.WEEK_OF_YEAR));
?

Week of the year.

Hi,
I need a query for week of the year. i.e. if we pass the date as parameter which week the date belong.
for ex. 31-AUG-2008 then 35th week, 01-SEP-2008 then 36th week.
please help to solvel

Yes, many ways! :-)
In general built-in functionality such as the IW format on date conversion is the efficient way to do things - why reinvent the wheel? But, if your week numbers are not the standard ones (and lots of organisations run their own calendars) perhaps you could use a join to a look-up table that maps dates to week numbers.

Week of the year number appears out of sync with the day of week the week #

Using the querry below on on a table where the pdate value is a sequential list of dates on an Oracle 11 database the results show the week of the year number changes on the day of the week number 7 not the day of the week number 1. Is there a patch to fix this?
select
pdate,
to_char(pdate,'D') dow,
to_char(pdate,'Day') Day_name,
to_char(pdate,'WW') week_of_the_Year
from daily_period_tab
where pdate >= '07-jan-11'

Hi,
Independent of you NLS settings, you can do this:
SELECT     TRUNC ( dt + 1
           , 'IW'
           ) - 1     AS sunday
FROM     table_x;The output in the sunday column will be the Sunday on or before dt. The "magic number" 1 indicates that your week starts 1 day before the ISO week, which starts on Monday.
Or if you want to use your NLS settings:
ALTER SESSION     SET NLS_TERRITORY= 'AMERICA';
SELECT     TRUNC ( dt
           , 'DY'
           )          AS sunday
FROM    table_x;
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

Problem in getting exact week of the year (Reposted)

Hi,
Can somebody respond to my posting please. I am posting it second time since nobody replied me till yet.
I make use of below code to get exact week of the year.
// Assumes the provided date is in 'ddMMM' format
SimpleDateFormat sdf = new SimpleDateFormat ( "ddMMM" );
Date parsedDate = sdf.parse( dateString );
Calendar calendar = Calendar.getInstance();
calendar.setTime( parsedDate );
int week = calendar.get( Calendar.WEEK_OF_YEAR );
Problem which I am facing is that when I pass "dateString" as
"22Mar" then it gives week as 13 instead of 12 for year 2007.
I find out that making use of cal.setFirstDayOfWeek( Calendar.MONDAY ); and cal.setMinimalDaysInFirstWeek( 4 ); statement eradicates the problem, ideally values should be
cal.setFirstDayOfWeek( Calendar.SUNDAY); and cal.setMinimalDaysInFirstWeek( 7); because for US first day of the week should be SUNDAY and minimum number of days should be 7 when I start from Sunday.
Please help me to understand the resolution. Is it correct or not?
Is it possible to solve the problem without specifying cal.setFirstDayOfWeek( Calendar.MONDAY ); and cal.setMinimalDaysInFirstWeek( 4 ).
This seems to be hardcoded for each year.

What am I missing? If you can't accept the ISO rules then you are going to define and implement your own algorithm. UsingSimpleDateFormat sdf = new SimpleDateFormat( "yyyy/MM/dd" );
        Date parsedDate = sdf.parse( "2007/01/01" );
        Calendar calendar = Calendar.getInstance();
        calendar.setFirstDayOfWeek(Calendar.MONDAY);
        calendar.setTime( parsedDate );
        for (int count = 0; count < 366; count++)
            int week = calendar.get( Calendar.WEEK_OF_YEAR );
            System.out.println(week + "\t" + sdf.format(calendar.getTime()));
            calendar.add(Calendar.DAY_OF_YEAR, 1);
        }I get the week as 12 not 13 but I specified THIS year. If you don't specify a year then, quite rightly, it takes 1970.

Convert date to week of the year in Query designer

Hi,
I have a requirement to convert date ( a characteristic in the query) to week of the year. For eg. if the date is 01/11/2008 then the week to be displayed is 2008/44.
Please not that the week is not populated in the Infocube of the same. So i need to convert it in the query designer only.
Please suggest if you have ideas.
Regards
Sapna

Hi,

Sql to get the Monday of every IW week in a year!

Hi There!
This is an SOS :) I had to get a query to give me all the Mondays of a IW week in a year. I think as per the IW weeks there are around 52.1 weeks in a year. So basically, I want the starting Monday of every week. I would then store those values in a variable and use them in APEX as column headers. Online I saw some samples not related with this, but where looping was done using the all_objects. Not sure if that is the right approach.
The problem is since this is not stored in any table, how can I loop like 52/53 times such that the output shows all the Mondays (date format) for a given year. Basically, the output would be 52/53 rows with a date(monday of the week).
Please help!
thanks,
Sun
