Answer: Create a rule in Amazon EventBridge that triggers every Saturday. Configure the rule to publish a notification to an SNS topic.
Amazon EventBridge (formerly CloudWatch Events) scheduled rules provide a serverless, highly available, and operationally efficient way to trigger actions on a recurring schedule. You can configure an EventBridge rule to trigger natively every Saturday using a cron expression, and seamlessly set an Amazon SNS topic as its target to distribute the notifications without managing underlying compute instances.
