The meaning of Day, Last in the Bible
(From International Standard Bible Encyclopedia)

(he eschate hemera): Repeatedly used by Jesus in John (John 6:39-40, John 6:44, John 6:54; John 11:24; John 12:48) for the day of resurrection and judgment (see ESCHATOLOGY OF THE NEW TESTAMENT). Compare the usage in the Old Testament (Isaiah 2:2; Micah 4:1) and the New Testament (Acts 2:17; II Timothy 3:1; II Peter 3:3; I John 2:18; Judges 1:18) of "last days" and "last time" to denote the Messianic age.

See LATTER DAYS; LAST DAYS; LAST TIME.

In John 7:37, "the last day, the great day of the feast" refers to the eighth day of the feast of Tabernacles. This closing day was observed as a Sabbath (Leviticus 23:36). On it the libation of water made on other days was not made; hence, the allusion of Jesus to Himself as the Giver of the living water.
