Weekname format

[#1]

Let say I have Weekname('2011-06-21') which return 2011/25, but behind it is the date of 20/06/2011 (first day of the week).

Now, I need the date of the first day of the same week in 2010 (ie. 2010/25). What would be the simplest solution.

I can't use AddMonths(Weekname('2011-06-21'),-12), as it won't be accurate

Is there such function Date#('2010/25','YYYY/WW')?

The display of '2011/25' must follow a certain format, if behind it stores numeric value. But which format is it?

Thanks in advance for your help

Hi,

What about

WeekName(AddYears('21/06/2011', -1))

Is this what you are looking for?

Hi Allano.

Hope this help

You can use this fuction to create the LY date:

MakeWeekDate( YYYY [ , WW [ , D ] ] )

Returns a date calculated from the year YYYY, the week WW and the day-of-week D.

If no day-of-week is stated, 0 (Monday) is assumed.

Examples:

makeweekdate( 1999,6,6 )	returns	1999-02-14
makeweekdate( 1999,6 )	returns	1999-02-08
