I see "the day of the Lord" (the future one) to consist of ALL THREE of the following aspects:
[1]--the 7 year tribulation upon the earth (the "IN THE NIGHT / DARK / DARKNESS" aspect [associated with the "NIGHT WATCHES" and "LAMPS LIT"]; Jesus' Own Personal Presence [physically / bodily / tangibly] is NOT REQUIRED as "OPENLY MANIFEST" for this aspect... but will commence when Jesus WILL [future to us] "STAND to JUDGE" Isa3:13, Rev5:6, (Lam2:3-4 in parallel language to that of 2Th2:7b-8a... "he hath DRAWN BACK HIS RIGHT HAND from before the enemy"... saying, in effect, "have at 'em!"--See also Hab1:6,12 where God HAS ORDAINED "the Chaldeans / Babylonians" FOR JUDGMENT / TO EXECUTE JUDGMENT... ; Jesus is the One OPENING "SEAL #1" from His position UP IN Heaven);
[2]--His Second Coming to the earth Rev19 (the "SUN of righteousness ARISE" aspect; THIS is His "MANIFESTATION of His presence / parousia" 2Th2:8b / "OPENLY MANIFEST" 1Tim6:15 [/Rev19:16 / 17:14], in conjunction with Rom8:19, Col3:4, 2Th1:10, etc...; This DOES require His Own Personal Presence when "EVERY EYE" existing on the earth SHALL SEE HIM, literally;
[3]--His 1000 yr reign on/over the earth (the "reign... GLORIOUSLY" aspect; I doubt we have much disagreement here, except if you are not also calling this [one aspect OF the VERY LONG TIME PERIOD known as] "the day of the Lord" as I am);
