The phrase alludes to a judgment for eternal rewards in 2 Corinthians 1:14 where it says 'we are your rejoicing, even as ye also are ours in the day of the Lord Jesus'. The phrase is also used in 1 Thessalonians 5:2 to refer either to the rapture or to the return of Jesus. This promise is also picked up in the New Testament, when Joel 2:28-32 is quoted in Acts 2:17-21. Reference to a specific day as being 'The Day of the Lord' is found in the Book of Daniel 12:12, 'Blessed is he who waits and comes unto 1,335 days.' So there are many events prophesied for the Day Of The Lord which need to take in account that the Jewish day begins with the sunset so it expects a dark phase ( Amos 5:18) at the beginning of this Age and then the sunrise with The Morning Star ( Revelation 22:16) followed by the plenty light ( Malachi 4:2)of the eternal day. The Hebrew Ч™Ц№Ч•Чќ and Greek бјЎОјОПЃО± both means a 24 hours day or an age or epoch. This has led Christian interpreters to equate it with Jesus' death. In Zephaniah 1:8, the Day of the L ORD is equated with 'the day of the L ORD's sacrifice'.

Yet Joel 2:32 holds a promise that on the Day of the Lord, 'everyone who calls on the name of the L ORD will be saved.' Thus, the day of the Lord is about God chastening his people, whether it be through the Babylonian invasion of Jerusalem or a locust plague described in Joel 2:1вЂ“11.

Because Israel had sinned, God would come in judgement on them. Wright suggests that the phrase was already a standard one, and Amos' hearers would take it to mean 'the day when Yahweh would intervene to put Israel at the head of the nations, irrespective of Israel's faithfulness to Him.' Yet Amos declares 'Woe to you who long for the day of the L ORD! Why do you long for the day of the L ORD? That day will be darkness, not light' ( Amos 5:18 NIV). Another early use of the phrase is in Amos 5:18-20. In the biblical canon, the earliest, direct use of the phrase is in Isaiah 2: 'For the day of the L ORD of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up and he shall be brought low' ( Isaiah 2:12). This concept develops throughout Jewish and Christian Scripture into a day of divine, apocalyptic judgment at the end of the world. Other prophets use the imagery as a warning to Israel or its leaders and for them, the day of the Lord will mean destruction for the biblical nations of Israel and/or Judah. In certain prophetic texts of the Hebrew Bible, the enemies of the Lord are Israel's enemies, and in these visions the day of the Lord brings victory for the people of ancient Israel. It relies on military images to describe the Lord as a ' divine warrior' who will conquer his enemies. It is used first by Isaiah and subsequently incorporated into prophetic and apocalyptic texts of the Bible. 2.1 'Lord's Day' as Christian day of worship.The expression may also have an extended meaning in referring to both the first and second comings of Jesus Christ. In the New Testament, the 'day of the Lord' may also refer to the writer's own times, or it may refer to predicted events in a later age of earth's history including the final judgment and the World to Come. This prophecy is read in synagogues on the Great Sabbath immediately preceding Passover. The prophet Malachi foretells the return of Elijah immediately preceding the 'great and terrible day of the L ORD'. This appears much in the second chapter of Isaiah which is read on the Sabbath of vision, immediately before the 10th of Av. In the Hebrew Bible, the meaning of the phrases refers to temporal events such as the invasion of a foreign army, the capture of a city and the suffering that befalls the inhabitants. ' The Day of the Lord' is a biblical term and theme used in both the Hebrew Bible ( Ч™Ц№Ч•Чќ Ч™Ц°Ч”Ч•ЦёЧ”) and the New Testament ( бјЎОјОПЃО± ОєП…ПЃОЇОїП…), as in 'The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the L ORD come' ( Joel 2:31, cited in Acts 2:20). The End of the World, also known as The Great Day of His Wrath by John Martin.
