Its somewhat different than the 1914 one as the 70 weeks prophecy isnt dependant on the day for a year principle. Bible commentries state this. The 70 weeks is the final biblical prophecy. Some people beleive the last week in this prophecy isnt fulfilled until the end of time.
The day year principle shouldnt be used in the 1914 prophecy because the word day isnt in the verse at all. The day year is not used consistently in every case in predictive prophecy.
