How do I schedule a Lambda function to execute everyday only during specific dates?

Question

Is there a way to schedule my Lambda to run everyday ONLY during specific dates ? Example:

• everyday between 1-July to 30-July
• everyday between 1-Oct to 30-Dec

Also, could I use these dates to set the schedule expression with eventbridge - https://docs.aws.amazon.com/eventbridge/latest/userguide/example_eventbridge_PutRule_section.html?

Answer 1

You can use the below cron expression to trigger the lambda function between 1-July and to 30-July

0 0 1-30 7 ? *

Explanation of the cron expression:

• The first field is for minutes (0).
• The second field is for hours (0).
• The third field is for days of the month (1-30).
• The fourth field is for months (7, July).
• The fifth field is for days of the week (? means every day).
• The sixth field is for years (* means every year).

You can set up a rule to run an AWS Lambda function on a schedule. Here is a tutorial that shows how to do it.

At a high level, here are the steps.

1. Create an AWS Lambda Function
2. Create a Rule via CloudWatch
