Open Minecraft World For 24 Hours Only

Have you ever tried Making A World With Your Friends but when its your friends World and he left you wont be able to play in his World? So I Came Up With an Idea How About You Enable Something in the world settings and enable keep Server online for 24 hours which it will make the world open for a limited time (limited time because realms exist) it will be open for one day and once that day finishes there will be a cooldown For one Day So Your gonna have to join the world normally like usual until the cooldown finishes.. But the thing is you must have the people you want to join your friends Hope This Idea Goes To All Version Like Java and bedrock / Preview and be accepted....
