  Buildkite uses the [Fugit](https://github.com/floraison/fugit) ruby gem for parsing cron strings, so features they support such as modulo are also supported by Buildkite schedules. See the [Fugit::Cron documentation](https://github.com/floraison/fugit#fugitcron) for more information and examples.   
  
  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.
