weekstart - script and chart function

This function returns a value corresponding to a timestamp of the first millisecond of the first day (Monday) of the calendar week containing date. The default output format is the DateFormat set in the script.

Syntax:  

WeekStart(date [, period_no = 0 [, first_week_day=0]])

Return data type: dual

Arguments:  

Argument Description
date The date to evaluate.
period_no shift is an integer, where the value 0 indicates the week which contains date. Negative values in shift indicate preceding weeks and positive values indicate succeeding weeks.
first_week_day

If you don't specify first_week_day, the value of variable FirstWeekDay will be used as the first day of the week.

If you want to use another day as the first day of the week, set first_week_day to:

  • 0 for Monday
  • 1 for Tuesday
  • 2 for Wednesday
  • 3 for Thursday
  • 4 for Friday
  • 5 for Saturday
  • 6 for Sunday

The integer returned by the function will now use the first day of the week that you set with first_week_day as base (0).
