Question about age and school


My son is just over a year old. We’ll be moving when he’s 6 and the school there requires kids be entered on the waiting list as soon as they’re eligible, so there that would be preschool, even though we won’t be living even in the same state. I’m having such a brain fail figuring this out. Can someone help?!

He has an October birthday, so I think that means he starts older than other kids right? If it’s 2 before a certain date to even start preschool, he waits that whole year before he can start at 3? So October 2019 birthday means he would register for preschool in 2022? Or 2023??

Help?! 😅😩
