23. Nothing is more common in the Word than for the word 'day' to be used to mean the particular time at which events take place, as in Isaiah,

The day of Jehovah is near. Behold, the day of Jehovah comes. I will make heaven tremble, and the earth will be shaken out of its place, on the day of My fierce anger. Its time is close at hand, and its days will not be prolonged. Isaiah 13:6, 9, 13, 22.

And in the same prophet,

Her antiquity is in the days of antiquity. On that day Tyre will be forgotten for seventy years, like the days of one king. Isaiah 23:7, 15.

Since 'day' stands for the particular time it also stands for the state associated with that particular time, as in Jeremiah, Woe to us, for the day has declined, for the shadows of evening have lengthened! Jeremiah 6:4

And in the same prophet,

If you break My covenant that is for the day and My covenant that is for the night, so that there is neither daytime nor night at their appointed time. Jeremiah 33:20, 25.

Also,

Renew our days as of old. Lamentations 5:21.

7649. 'Which your fathers and your fathers' fathers have not seen, from the day they have been on the ground even to this day' means that since ancient times no such falsity had existed in the Church as existed there now. This is clear from the meaning of 'which (that is, the locusts) they have not seen' as no such falsity had existed, 'locusts' being falsity in outermost parts, see above in 7643; from the meaning of 'fathers, and fathers of fathers' as since ancient times; and from the meaning of 'the ground' as the Church, dealt with in 566, 1068. 'From the day they have been on it even to this day' means the state in which the Church existed from that time to this, the state being meant by 'the day', see 23, 487, 488, 493, 2788, 3462, 4850. For more on this, see 7686.
