Weekday(date, [timezone])
```

Function arguments:

* **date** (required) - the date or column containing date values from which the weekday is determined
* **timezone** (optional) - the [IANA time zone](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) (e.g., “America/Los\_Angeles”) to convert the date value to before evaluating the weekday

### Example

Weekday(Date("2017-12-01"))
```

Evaluates the specified date (December 1, 2017) to determine the day of the week and returns `6` to represent Friday, the sixth day of the week.
