Gold futures delivery period refers to a specific delivery date of gold after the expiration of the gold futures contract.

For example, gold 0905 is the gold contract in May 2009. Then the expiration date of the contract is the last day at the end of May. Before the expiration of the contract, the contract holders (buyers and sellers) agreed that May 3 1 day was the delivery date, so on May 3 1 day, both parties delivered the gold, the buyer paid the seller, and the seller delivered the gold to the buyer.
