Start week from Monday in the Autocalendar script

[lwp89]

How to get the week start from Monday?

When loading data using the Data Manager, the script generates an auto-calendar script where it creates very useful fields such as Week Number, Preivous week tag, etc,. (below is the script sample)

[autoCalendar]: 
  DECLARE FIELD DEFINITION Tagged ('$date')
FIELDS
  Dual(Year($1), YearStart($1)) AS [Year] Tagged ('$axis', '$year'),
  Dual('Q'&Num(Ceil(Num(Month($1))/3)),Num(Ceil(NUM(Month($1))/3),00)) AS [Quarter] Tagged ('$quarter', '$cyclic'),
  Dual(Year($1)&'-Q'&Num(Ceil(Num(Month($1))/3)),QuarterStart($1)) AS [YearQuarter] Tagged ('$yearquarter', '$qualified'),
  Dual('Q'&Num(Ceil(Num(Month($1))/3)),QuarterStart($1)) AS [_YearQuarter] Tagged ('$yearquarter', '$hidden', '$simplified'),
  Month($1) AS [Month] Tagged ('$month', '$cyclic'),
  Dual(Year($1)&'-'&Month($1), monthstart($1)) AS [YearMonth] Tagged ('$axis', '$yearmonth', '$qualified'),
  Dual(Month($1), monthstart($1)) AS [_YearMonth] Tagged ('$axis', '$yearmonth', '$simplified', '$hidden'),
  Dual('W'&Num(Week($1),00), Num(Week($1),00)) AS [Week] Tagged ('$weeknumber', '$cyclic'),
  Date(Floor($1)) AS [Date] Tagged ('$axis', '$date', '$qualified'),
  Date(Floor($1), 'D') AS [_Date] Tagged ('$axis', '$date', '$hidden', '$simplified'),
  If (DayNumberOfYear($1) <= DayNumberOfYear(Today()), 1, 0) AS [InYTD] ,
  Year(Today())-Year($1) AS [YearsAgo] ,
  If (DayNumberOfQuarter($1) <= DayNumberOfQuarter(Today()),1,0) AS [InQTD] ,
  4*Year(Today())+Ceil(Month(Today())/3)-4*Year($1)-Ceil(Month($1)/3) AS [QuartersAgo] ,
  Ceil(Month(Today())/3)-Ceil(Month($1)/3) AS [QuarterRelNo] ,
  If(Day($1)<=Day(Today()),1,0) AS [InMTD] ,
  12*Year(Today())+Month(Today())-12*Year($1)-Month($1) AS [MonthsAgo] ,
  Month(Today())-Month($1) AS [MonthRelNo] ,
  If(WeekDay($1)<=WeekDay(Today()),1,0) AS [InWTD] ,
  (WeekStart(Today())-WeekStart($1))/7 AS [WeeksAgo] ,
  Week(Today())-Week($1) AS [WeekRelNo] ;

DERIVE FIELDS FROM FIELDS [Release Date] USING [autoCalendar] ;

The date field name is [Release Date] and the above script produces below additional fields

How do I make the Sunday (09-18-2022) included in previous week instead of this week?

• So the weeksAgo value for that date (09-18-2022) becomes 1 instead of 0?
• and the weeksAgo value for that date (09-11-2022) becomes 2 instead of 1?

basically a week should be Monday to Sunday not Sunday to Saturday.

I hope I have explained it well 🙂

Default Week start is defined by the system variable FirstWeekDay. It is also possible to define the week start day in the week function, like this:

week(DateField, 0)

Thank @Vegar I did set the FirstWeekDay = 0 and its fixed 🙂

Hi @Vegar ,

Just another related question.. Now that I have the correct flag for identifying dates that belongs to previous week.

How to find the Week start date and Week end date of the previous week? (where ReleaseDate.AutoCalendar.WeekAgo = 1) 

I looked into the WeekStartDate and WeekEndDate function but could not figure out how to best use them to find the start and end date of previous week!

Thanks

• What if you do something like this: 

WeekStart(dateField , -1 , 0)

WeekEnd(dateField , -1 , 0) 

OR dayname(WeekEnd(dateField , -1 , 0))
