==== Weekly Schedule

A <<trigger-schedule, `schedule`>> that triggers at a specific day and time
every week. To use the `weekly` schedule, you specify the day and time (or days
and times) when you want the scheduler to start the watch execution with the `on`
and `at` attributes.

You can specify the day of the week by name, abbreviation, or number (with Sunday
being the first day of the week):

* `sunday`, `monday`, `tuesday`, `wednesday`, `thursday`, `friday` and `saturday`
* `sun`, `mon`, `tue`, `wed`, `thu`, `fri` and `sat`
* `1`, `2`, `3`, `4`, `5`, `6` and `7`

Times are specified in the form `HH:mm` on a 24-hour clock. You can also use the
reserved values `midnight` and `noon` for `00:00` and `12:00`.

===== Configuring a Weekly Schedule

To configure a once a week schedule, you specify the day with the `on` attribute
and the time with the `at` attribute. For example, the following `weekly` schedule
triggers once a week on Friday at 5:00 PM:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "weekly" : { "on" : "friday", "at" : "17:00" }
    }
  }
}
--------------------------------------------------

NOTE: You can also specify the day and time with the `day` and `time` attributes,
      they are interchangeable with `on` and `at`.

===== Configuring a Multiple Times Weekly Schedule

To configure a `weekly` schedule that triggers multiple times a week, you can
specify an array of day and time values. For example, the following `weekly`
schedule triggers every Tuesday at 12:00 PM and every Friday at 5:00 PM:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "weekly" : [
        { "on" : "tuesday", "at" : "noon" },
        { "on" : "friday", "at" : "17:00" }
      ]
    }
  }
}
--------------------------------------------------

Alternatively, you can specify days and times in an object that has `on` and
`minute` attributes that contain an array of values. For example, the following
`weekly` schedule triggers every Tuesday and Friday at 12:00 PM and 17:00 PM:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "weekly" : {
        "on" : [ "tuesday", "friday" ],
        "at" : [ "noon", "17:00" ]
      }
    }
  }
}
