There is an error in the limited warranty date.
I bought a new MacBook on 9/21/2025 and after opening the device I was surprised that the limited warranty continues until April 2026
MacBook Air 13″, macOS 26.0
Exactly where did you buy it?
The warranty clock starts ticking when it is originally sold by Apple or an authorized retailer. If you bough it from an unauthorized retailer the warranty started a while ago.
