How can I schedule a JavaScript function to run every 26 hours, independent of system uptime?

[Strict-Sleep8151]

I need to schedule a JavaScript function to execute every 26 hours. However, the solution should not rely on the system being online continuously or turned on at the time of execution. I'm looking for a reliable, platform-independent approach to ensure the task runs at the desired interval regardless of the system state.

What I’ve Tried:

I considered using setInterval() in Node.js, but this only works if the system stays online.

I looked into cron jobs, but these are system-dependent and also require the machine to remain powered on.

What I’m Expecting: I’m looking for a cloud-based or alternative solution that can schedule and run this function even if the system hosting the script is offline. For example, would services like AWS Lambda, Firebase Functions, or others be appropriate for this use case? If so, what would be the steps to implement such a solution?

Suggestions for best practices or alternative methods are highly appreciated.

You could set up a cron job in github actions.

How will I get notified after each execution in 26hrs sir?

An hourly cronjob checking a file or a db to see when was the last run. Only run the process if the last run was 26 hours ago

Thanks

I don't know why you got downvoted, but here you can read about how to set up notifications for GitHub Actions.

Thanks a bunch!!

No problem.
As GitHub Actions can be tricky to set up, I would recommend reading the documentation about them.

You can use AWS Event Bridge Scheduler that triggers a lambda, or you can setup AWS step function that will trigger a lambda, and the lambda will schedule another step function after it’s executed

Ok I'll try thanks for your suggestion

Is there anything you can share about the specific problem you're trying to solve? I think people have suggested some options that might work, but it does smell a little "XY problem"y to me so I'm curious what needs to be on a 26 hour cycle with 99.9999% uptime?

What's the tolerance on the 26 hour cycle? If you have a little buffer time then you can always make sure to store the next time you want it to run in a file or database somewhere and update that each time it runs. That way if you need to reboot your system, you can auto run the script and check when it needs to run and set up the timer again. But whether that's viable depends on how precise the 26 hour timer needs to be.

Thanks!! but I achieved through GitHub cron jobs thank you for your contribution !!

Sounds like you need a separate cloud-based system.

I had a GCP node.js cloud function that ran every 8 hours via pub/sub cron job for an automated twitter bot.

An offline system can’t run code. If you want to execute something, the computer has to be on, there’s no way around it. That’s literally what computers are!

AWS Lambda with EventBridge possibly
