The four digits after the futures contract code indicate the delivery time of the futures contract: the first two digits are the delivery year and the last two digits are the delivery month.

For example, the futures Shanghai Copper 14 12 contract indicates that the futures product is a metal copper contract of Shanghai Futures Exchange, and the delivery time is 20 14 12. (Last trading day: 15 of the delivery month of the contract (postponed in case of legal holidays), and the delivery date: five consecutive working days after the last trading day. )

The above is only the delivery situation of Shanghai Futures Exchange, and the delivery time of other exchanges is similar. You can go to official website Exchange to see the details.

I hope it will help, I hope it will be adopted ~
