The worst warranty system ever

Very odd way to warranty product. On 10 Feb 2022, I purchased a new Dell Monitor from Incredible Connection and upon trying to register the product on Dell online, the purchase date (aka the warranty coverage starting date) was 30 Nov 2021 instead of 10 Feb 2022? Other brands such as LG and Samsung do the warranty coverage from the purchase date, not from the shipment one? I am confused. Dell online-only asked for a service tag. Neither asked for proof of purchase nor allowed the customer to indicate the purchase date. A total warranty waste.
