   <table>
     <thead>
  
positive.code:     <tr><th><code>@daily</code> or <code>@midnight</code></th><td>Every day at midnight UTC</td><td><code>0 0 * * *</code></td></tr>
      <tr><th><code>@weekly</code></th><td>Every week at midnight Sunday UTC</td><td><code>0 0 * * 0</code></td></tr>
      <tr><th><code>@monthly</code></th><td>Every month, at midnight UTC on the first day</td><td><code>0 0 1 * *</code></td></tr>

negative.code:  │ │ │ │ │          ┌─── time zone name or offset (optional)
   │ │ │ │ │          │
   * * * * * Australia/Melbourne
  ``` 
  
  A time zone can optionally be specified as the last segment, either as an [IANA Time Zone name](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) like `Australia/Melbourne` or `Europe/Berlin`, or as an offset from UTC like `+09:00` or `-05:00`. If no time zone is given, the schedule will run in UTC.
  
  #### Supported Extensions
  
  Buildkite supports several extensions to the standard POSIX cron syntax.
  
  ##### The `/` operator
  
  The slash operator allows you to specify step values within ranges. For example, `*/10 * * * *` would run every ten minutes.
  
  ##### `L` or `last` token
  
  Using `L` or `last` in the _day of month_ field represents the last day. Thus `0 0 L * *` represents midnight on the last day of the month, and `0 0 -2-L * *` represents the last two days of the month.
  
  ##### Modulo
  
  Using the modulo extension allows you to create schedules for more specific subsets of times. For example, `0 0 * * 0%3` represents midnight on every third Sunday. You can also use the `+` operator to offset this, so for instance you could use `0 0%2+1 * * *` to schedule a build at the top of every odd hour, whereas `0 0%2 * * *` would run every even hour.
  
  #### Examples
  
  <table>
    <tr><th><code>*/10 * * * *</code></th><td>Every 10 minutes</td></tr>
