What this card says
Why do we need it?
OS cron on a student laptop is off when the laptop sleeps. Cloud schedules stay on.
What is it?
Amazon EventBridge Scheduler (or rules) invokes targets on a cron or rate expression in a timezone you choose.
How to do it
Create schedule → cron 0 21 * * ? * → timezone Asia/Calcutta → flexible window off → target your Lambda ARN.
Asia/Calcutta
Example
