True or False: By default, weeks in Looker start on Monday.

In Looker, the default setting for the start of weeks is designated as Sunday, not Monday, making the statement that weeks start on Monday false. It's important to note that while the default behavior is to start the week on Sunday, organizations can adjust their week definition according to various regional or business needs. This adjustment is done through the configuration settings. Therefore, while the default setting is for weeks to start on Sunday, users have the option to change this to Monday or any other day based on their requirements.

Options suggesting that it can be configured or depends on user settings point towards the flexibility of Looker in tailoring the week start according to specific needs, which is accurate. However, since the question specifically asks about the default setting, the answer identifying it as Monday is indeed not correct.
