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.

4850. 'The days were multiplied' means a change of state. This is clear from the meaning of 'the days being multiplied' as undergoing a change of state, for 'day' or a time in the internal sense means state, 23, 487, 488, 893a, 2788, 3462, 3785, and 'being multiplied' when used in reference to days or times means undergoing a change. The fact that a change of state is the meaning is also evident from the details that follow. The expression 'to be multiplied' is used because it implies a change of state so far as truths are concerned; for 'to be multiplied' is used in reference to truths, 43, 55, 913, 983, 2846, 2847. Since the terms state and change of state are being used time and again, and yet few know what a state or a change of state is, a statement needs to be made about what these are. Neither time and the passage of time nor space and the extension of space can be associated with the interior aspects of the human being - that is to say, with his affections and his thoughts formed by these - because his affections and thoughts are not located in time and place, though to the senses in the world they do seem to be thus located. Rather, they are located in the interior things which correspond to time and place. The things which correspond to them cannot be called anything else than states, for no other term exists to describe the things that correspond to time and place. A change of state in interior things is said to take place when the affections and resulting thoughts in a person's mind or disposition (mens seu animus) undergo change, as when sadness turns to joy, or joy back to sadness, when ungodliness turns to godliness or devotion, and so on. These changes are called changes of state and are attributable to affections and, insofar as thoughts are governed by these, to thoughts also. But the changes of state which thoughts held within affections undergo are like those of individual parts within their general wholes, compared with which they are variations.
