The day in the month that commodities on a futures contract have to be delivered is called the Delivery date.
Every forward and futures contract contains a delivery date on which the corresponding commodity should be delivered to the holder of the contract provided he/she has the contract upto the date of maturity.
Points to remember:
A future contract is generally referred by its delivery month.
The exchange market that deals with the futures contract should put forward the specified period during which the delivery can be made.
For a few of the futures contract, the delivery period is the whole month, for some of it, it is a specific date.
Example: If a contract specifies the delivery date to be March 2019, then the futures contract will have to be delivered within the specified month of March.
