Hello Doves,
 
Take 2300/360 = 6..388889 prophetic years.  Then go forward 6.388889 years from Jan. 20/21, 2012, and you should have the day when the temple will be cleansed.  I don't have the means to calculate the date, but it appears to be around May 14, 2015.
 
OR
 
Take 2300/365.25 = 6.297 civil years.  And do the same as above.
 
There's only a few days discreptancy between the two calulations.
 
In Christ,
Greg
