### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/aws/events/schedule) # Schedule The following config will attach a schedule event and causes the function `crawl` to be called every 2 hours. The configuration allows you to attach multiple schedules to the same function. You can either use the `rate` or `cron` syntax. Take a look at the [AWS schedule syntax documentation](http://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html) for more details. ```yaml functions: crawl: handler: crawl events: - schedule: rate(2 hours) - schedule: cron(0 12 * * ? *) ``` ## Enabling / Disabling **Note:** `schedule` events are enabled by default. This will create and attach a schedule event for the `aggregate` function which is disabled. If enabled it will call the `aggregate` function every 10 minutes. ```yaml functions: aggregate: handler: statistics.handler events: - schedule: rate: rate(10 minutes) enabled: false input: key1: value1 key2: value2 stageParams: stage: dev - schedule: rate: cron(0 12 * * ? *) enabled: false inputPath: '$.stageVariables' - schedule: rate: rate(2 hours) enabled: true inputTransformer: inputPathsMap: eventTime: '$.time' inputTemplate: '{"time": , "key1": "value1"}' ``` ## Specify Name and Description Name and Description can be specified for a schedule event. These are not required properties. ```yaml events: - schedule: name: your-scheduled-rate-event-name description: 'your scheduled rate event description' rate: rate(2 hours) ```
