Research Report on Second Chronicles 2
The sacrifice given by Solomon at the dedication of the temple appears to indicate the length of time the temple would stand. Since the exact date of his dedication is unknown, we start at the end of Solomon’s temple and work backwards to suggest the dedication date. The math suggests this works.
Two times in Second Chronicles 2 the number of alien slaves working for Solomon’s temple project are given. 70,000 are carriers, 80,000 are stone cutters and 3,600 are foremen to oversee the work.  
These counts appear to be related to the future history of Solomon’s kingdom. Since the specific year of the temple dedication is not given with precision, the following takes these counts backwards from the fall of the city and the burning of the buildings, including Solomon’s temple.
The epoch used in the following report is from Jeremiah 52:12, 2 Kings 25:8 gives a date three days earlier. I’ve selected the following since it is an even multiple of 10 which is prefered in the long distance counts generally. The 2 Kings date puts the burning on the previous Saturday, the Sabbath. If that is the prefered date then the report would generate all dates three days earlier.

The intermediate dates may not be correct as the order of the 3 sets of men is not clear. The start point, though is highly suspicious as providing a key date in the dedication of the Solomon’s temple. It was the 8th month of the year 487 from Exodus that Solomon finished the temple in all its detail.
Now here approaching the great assemblies at the dedication of Solomon’s temple, recorded in the 7th month, but without the year, we get this reference. Odds are good this is the year of that dedication, for it had been standing for the better part of a year while Solomon’s team continued to work on the palace, taking another 12 years to finish it.
This count of the alien slaves under Solomon’s control appears to be the count of days that this temple would stand, before being burned down by Nebuchadnezzar’s alien invaders so many years later.
