# TIME_OF_WEEK

Adds a `TIME_OF_WEEK` label to anomalies that happen during a specific time of the week. For instance, can be used to filter anomalies that happen on Saturday.

## Inputs

The info source is the output of the detector. Labels are applied to the anomalies of this input.

```json theme={null}
{
  "sourcePlanNode": "anomalyDetector"
}
```

## Parameters

| name                       | description                                                                             | default value   |
| -------------------------- | --------------------------------------------------------------------------------------- | --------------- |
| `component.daysOfWeek`     | A list of days to match. Eg `["MONDAY", "SATURDAY"]`.                                   | `[]` (no match) |
| `component.hoursOfDay`     | A list of hours to match. Eg `[0,1,2,23]`                                               | `[]` (no match) |
| `component.dayHoursOfWeek` | A map of `<day, List<hour>>` to match. Eg `{"FRIDAY": [22, 23], "SATURDAY": [0, 1, 2]}` | `{}` (no match) |

To determine days, the timezone defined in [metadata\$timezone](/thirdeye/alert-configuration#timezone) is used.
