Hi Zexi1,
You can input any date for that registration for Razer Synapse.
However, for any Limited Warranty claim, a valid Proof of Purchase is required. A valid Proof of Purchase is defined as one of the following:

• A dated sales receipt from an authorized Razer Dealer or Reseller. The receipt must show the Product description and price.
  
• A dated official e-mail from an authorized on line Razer Dealer or Reseller confirming purchase and shipment of Product. The confirmation e-mail must show the Product description and price.
  
• An order number from the Razer.com web site
