Definition
You can adjust the day that Looker considers to be the start of a week with the week_start_day parameter. Using week_start_day affects:
- The way that data appears in your tables
 - The sort order of the tables
 - The operation of filters
 
The week_start_day parameter works with three of the four week-related timeframes:
| timeframe | Works with week_start_day? | 
|---|---|
day_of_week_index | 
Yes | 
week | 
Yes | 
day_of_week | 
Yes | 
week_of_year | 
No | 
week_start_day does not work with week_of_year because that timeframe is based on the ISO standard, which uses Monday weeks.
Examples
Adjust weeks to start on Sunday instead of Monday:
week_start_day: sunday
