It fits with the millennial day theory.
A day is like a thousand years, a thousand years is like a day.
For the Lord that is.
We're counting up the end of 6000 years of Bible Genealogy.
Six one thousand year days.
So a seventh one thousand year day fits the plan.
And you can have a thousand symbolic cattle on a thousand symbolic hills, but there's no such thing as symbolic "time".
All of the 18 prophetic time periods, even those translated day for a year, in Daniel and Revelation are literal time.
1. Time, times and half a time (saints persecuted – Daniel 7:25)
2. 2,300 evenings and mornings (until temple restored – Daniel 8:14)
3. 70 weeks (determined upon the Jews, Messiah crucified – Daniel 9:24,25)
4. Time, times and half a time (when completed, power of the holy people – Daniel 12:7)
5. 1,290 days (from the end of the daily to the setting up of the abomination – Daniel 12:11)
6. 1,335 days (blessed is the one who waits for and reaches this day – Daniel 12:12)
7. Half hour of silence (at the opening of the 7th seal – Revelation 8:1)
8. 5 months (length of torture upon those not having the seal of God – Revelation 9:5)
9. Hour, day, month and year (event when war begins – Revelation 9:15)
10. 42 months (Gentiles trample holy city – Revelation 11:2)
11. 1,260 days (Two Witnesses empowered for this length of time – Revelation 11:3)
12. 3.5 days (bodies of Two Witnesses lie in the street – Revelation 11:11)
13. 1,260 days (woman fled into the desert – Revelation 12:6)
14. Time, times and half a time (woman fled into the desert – Revelation 12:14)
15. 42 months (persecution of saints – Revelation 13:5)
16. One hour (ten kings join with beast – Revelation 17:12)
17. One day, one hour (Babylon’s destruction begins – Revelation 18:8,19)
18. 1,000 years (Satan in the abyss – Revelation 20:2)
