==== {watcher} Daily schedule

<titleabbrev>Daily schedule</titleabbrev>
++++

A <<trigger-schedule,`schedule`>> that triggers at a particular time
every day. To use the `daily` schedule, you specify the time of day (or times)
when you want the scheduler to start the watch execution with the `at` attribute.

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`, and
<<specifying-times-using-objects,specify times using objects>>.

NOTE: If you don't specify the `at` attribute for a `daily` schedule, it defaults
      to firing once daily at midnight, `00:00`.

===== Configuring a daily schedule

To configure a once a day schedule, you specify a single time with the `at`
attribute. For example, the following `daily` schedule triggers once every
day at 5:00 PM:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "daily" : { "at" : "17:00" }
    }
  }
}
--------------------------------------------------

===== Configuring a multiple times daily schedule

To configure a `daily` schedule that triggers at multiple times during the day,
you specify an array of times. For example, the following `daily` schedule
triggers at `00:00`, `12:00`, and `17:00` every day.

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "daily" : { "at" : [ "midnight", "noon", "17:00" ] }
    }
  }
}

[[specifying-times-using-objects]]
===== Specifying times using objects

In addition to using the `HH:mm` string syntax to specify times, you can specify
a time as an object that has `hour` and `minute` attributes.

For example, the following `daily` schedule triggers once every day at 5:00 PM:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "daily" : {
        "at" : {
          "hour" : 17,
          "minute" : 0
        }
      }
    }
  }
}
--------------------------------------------------
// NOTCONSOLE

To specify multiple times using the object notation, you specify multiple hours
or minutes as an array. For example, following `daily` schedule triggers at
`00:00`, `00:30`, `12:00`, `12:30`, `17:00` and `17:30` every day:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "daily" : {
        "at" : {
          "hour" : [ 0, 12, 17 ],
          "minute" : [0, 30]
        }
      }
    }
  }
}

[[specifying-time-zone-for-daily-schedule]]
===== Specifying a time zone for a daily schedule
By default, daily schedules are evaluated in the UTC time zone. To use a different time zone,
you can specify the `timezone` parameter in the schedule. For example, the following
`daily` schedule triggers at 6:00 AM and 6:00 PM in the `Pacific/Galapagos` time zone:

[source,js]
--------------------------------------------------
{
  "trigger" : {
    "schedule" : {
      "timezone" : "Pacific/Galapagos",
      "daily" : {
        "at" : {
          "hour" : [ 6, 18 ],
          "minute" : 0
        }
      }
    }
  }
}
