“Day” From Boyd’s Bible Dictionary:

(shining). Natural Hebrew day from sunset to sunset (Gen. 1:5; Ex. 12:18). Sabbath the only day named; others numbered (Lev. 23:32). Morning, noon, and evening divisions (Psa. 55:17). Hours introduced (Dan. 3:6; John 11:9). Indefinite time (Gen. 2:4); of birth (Job 3:1); of ruin (Hos. 1:11); of judgment (Joel 1:15); of Christ’s kingdom (John 8:56).

“Year” From Boyd’s Bible Dictionary:

The Hebrew year was sacred and civil, with two beginnings
The sacred year began with the month Abib, April, the civil with the month Tisri, October. The months were lunar, twelve in number, with, of course, the necessary intercalary month ve-adar at the proper time, about every three years. As divided by seasons, the year was solar. There were two seasons, summer and winter (Psa. 74:17; Jer. 36:22; Amos 3:15; Zech. 14:8).

“Day” From Concise Bible Dictionary:

Besides the ordinary application of the word, it is used in scripture as defining different periods. The term “that day” often occurs in the Prophets and in the New Testament referring to the Messiah’s day, sometimes connected with judgment and sometimes with blessing, the context of each passage showing its application. The subject generally may be divided into:
1. The days of the Law and the Prophets, which extended from the giving of the law until the coming of the Messiah. “At the end of these days [God] has spoken to us in [His] Son,” as Hebrews 1:2 should read. This introduced Messiah’s Day. But He was rejected and His reign postponed.
2. In the meantime the Day of Grace supervenes, during which the church is being called out. The Lord Jesus wrought out redemption, ascended to heaven, and sent down the Holy Spirit. Of this time He said “In that day ye shall know that I am in My Father, and ye in Me, and I in you” (John 14:20: Compare also John 16:23, 26). The present period is referred to as man’s day (1 Cor. 4:3, margin). These are also “the last days” in which scoffers would come (2 Pet. 3:3; Jude 18).
3. Messiah’s Day, when He returns in judgment and then to reign. “The day is at hand” (Rom. 13:12; Heb. 10:25). “The day shall declare it” (1 Cor. 3:13). It is also called “the last day” (John 6:39-54; John 11:24; John 12:48). And it is called “the great day.” Elijah will come before the great and dreadful day of the Lord (Mal. 4:5). The kings of the earth will be gathered to the battle of that great day of God Almighty (Rev. 16:14). It is also called “the day of Christ” and “the day of Jesus Christ” (Phil. 1:6, 10; Phil. 2:16; compare 1 Cor. 1:8; 2 Cor. 1:14).

“Time, Times” From Concise Bible Dictionary:

Time has been described as “the measure of motion,” as seen in the movements of the heavenly bodies; or as “the duration of periods,” of which we can conceive a beginning and an ending. It stands in contrast to ETERNITY, of which no beginning and no ending can be conceived.
Christians are exhorted to “redeem the time” (Eph. 5:16; Col. 4:5). This does not mean “to make up for lost time”; but to seize every favorable opportunity. In Daniel 2:8 the king said that the wise men sought “to gain the time,” that is, obtain a delay in the hope that the king might relent, or that something might happen that would save them.
As to the various events foretold by God that have yet to come to pass, it is not for the Christian to know “the times or the seasons which the Father hath put in his own power” (Acts 1:7). But, on the other hand, when two events have been foretold, the one of which must take place before the other (as the “rapture” of the saints before the day of the Lord when He will return with His saints), Christians are expected to know about them, for the apostle Paul writes “Of the times and the seasons, brethren, ye have no need that I write unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night” (1 Thess. 5:1-2). If is further explained in 2 Thessalonians 2:3-10, that the day of the Lord could not come before the revelation of the Antichrist. Still as to the when of this and of the “rapture” of the saints, we are not to know, but are to be always ready for the latter.
Of the children of Issachar it is said that they were men “that had understanding of the times, to know what Israel ought to do” (1 Chron. 12:32). They understood the mind of God, namely, that David should be king of the whole of the twelve tribes. So the Holy Spirit can direct the saints to the particular line of truth most suitable to the period in which they live, and teach them what they ought to do; as, for example, a line of truth and action for the present state of the church is pointed out in the Second Epistle to Timothy, agreeing, as it does, with the later addresses to the Seven Churches in Revelation 3.
The word “time” is used in Daniel 7:25; Daniel 12:7; Revelation 12:14, for a “year”: hence “time, times, and a half “ signify three years and a half. See SEVENTY WEEKS. The expression in Revelation 10:6, “time should be no longer,” is better translated “there should be no longer delay.”

“Year” From Concise Bible Dictionary:

Under the word MONTHS it has been stated that the Jews reckoned the months to consist alternately of twenty-nine and thirty days, being therefore in twelve months eleven and a quarter days short of the year. To remedy this an additional month was added about every three years. In the various data given for the last half of the last of Daniel's Seventy Weeks, it will be seen that all the months are reckoned as having thirty days; thus “a time, times, and a half “ in Daniel 12:7 and Revelation 12:14 point out three and a half years: this period is again called forty two months in Revelation 11:2 and Revelation 13:5; and again twelve hundred and sixty days (Rev. 11:3; Rev. 12:6). The prophetic year may therefore be called three hundred and sixty days. See MONTHS and SEASONS.
