Hello,
I think scheduled Reserved Instances do not cease being available after some time as long as your usage matches the schedule.

March 19, 2021Understanding AWS Reserved Instances
It's a correct, but not complete answer. You can only reserve the *compute* portion of an instance. If you exceed free-tier usage, you will still pay for storage (EBS Volumes), Bandwidth, EIPs, Load Balancers, and bandwidth. At least EB apps usually have most of those things associated with them. You're prepaying for a discount on the hourly cost of compute, basically. It is generally worth it. They also recently introduced AWS Savings Plans, which is like reserved instances but way more flexible. Again, you're only reserving compute, but you can say "I promise to spend $X/hr on compute" and the amount of usage they charge you drops by a decent percent, like 30% or more in many cases. I'd recommend digging in to your bill in more detail and see where the charges actually are. Two t2.micro instances should cost nearly nothing at $0.0116/hr, or about 8.50 a month each, in us-east-1.

What would make this a REAL killer app is if AWS itself allowed us to schedule our instances to stop and start.
I'm actually wondering why this functionality hasn't been released yet.
(Though I will say with Lambda this automation becomes much easier)
