Hi Brian,

According to the ISO guidelines a week starts always with Monday and the
majority of the days must be from the new year. In this way January 4th is
always in the first week.
So you simply need to determine the first Monday within the year and then
add the week according the ISO guidelines - 1 multiplied with 7 days to the
first Monday's date:
Something like this:

Select Next_Day(Date(Year(yourDate) concat '-01-04') - 7 Days, 'MON') +
((Week_Iso(YourDate) -1) * 7) Days MondayWeek
From your Table


Mit freundlichen Grüßen / Best regards

Betreff: Get Start Date of a Week Number

Hello All,

I have the need to get the date of the first day of the week based on a week
number. I've looked thorough lots of date functions and can't seem to see a
way to get the date of the first day of the week for a particular week
number. Maybe I need a multi-step process, but I am just struggling to see
it.

The date can be based off Sunday or whatever arbitrary day could be
considered as the first day of the week, if that helps.

The data is planning data so I really just need to show it as a quantity
along with a date, but the date needs derived from a week number.

As an example, if I had week number of 1, the date might be 12/29/2014, week
2 would give me 1/5/2015 and so on.

Can anyone provide some suggestions on a method to get to a date based off
the week number?

Thank you.
