**Tell us about your request**
What do you want us to build?
We are looking to stop some services on weekends.

**Which service(s) is this request for?**
ECS -> Service -> Fargate

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
Right now, the only way to "stop" the services is to change the desired number of tasks to 0, and works well, but I cannot find any easy way to do this change to several of our services on weekends only. The services should run from Monday at 8 AM to Friday at 5 PM only.

**Are you currently working around this issue?**
How are you currently solving this problem?
Manually and potentially, I'm planning to write a lambda or something like that.

**Additional context**
Anything else we should know?
N/A

No repository file, test, or implementation entry point is identified in the request. Start by clarifying how ECS Fargate services should apply the Monday 8 AM to Friday 5 PM schedule and whether the desired task count is the control, then define the behavior that would replace the current manual changes or planned Lambda workaround.
