Okay, this is even confusing for me, so please try to bear with me.

I am working on a "presentation" to give to a JW family member to defend myself when the fade comes up. I want it to be something that will make them think and this is what I have come up with.

This person believes in the whole 1914 chronology bible prophecy crap and can't believe this isn't the Truth when they are so right about the date. But I see a flaw with the way it was calculated and I need input to tell me whether I'm cracked or this might really work- get him to think.

According to the WTS, " In prophecy, a year averages 360 days, or 12 months of 30 days each... So the king’s "seven times," or seven years, were 360 days multiplied by 7, or 2,520 days. " Since these are "prophetic days" they do a day for a year. So good so far.

" The "seven times" of earth’s domination by Gentile powers without interference by God’s Kingdom therefore spanned 2,520 years. They began with the desolation of Judah and Jerusalem in the seventh lunar month (Tishri 15) of 607 B.C.E. (2 Kings 25:8, 9, 25, 26) From that point to 1 B.C.E. is 606 years. The remaining 1,914 years stretch from then to 1914 C.E. Thus, the "seven times," or 2,520 years, ended by Tishri 15, or October 4/5, 1914 C.E."

Here's my problem with this: Since they are saying that the 2,520 days are 360 days each, per bible prophecy, should they adjust that number since we don't calculate time that way anymore? 2520 yrs x 360days/yr = 907200days. To convert this period into our calendar year of 365.25 days we divide the period of 907,200 days by 365.25 days to reach a total of 2,483.8 of our modern calendar years. 607 bce + 2520 yrs = 1913 plus one year because there is no zero year. But 607 bce + 2483.8 = 1876.8 plus one year = 1877.8 or mid 1877.

Am I wrong or should they stick with the same calculating method? I mean, 2520 years with 360 days each just does not equal 1914 when added to 607. Any input would be helpful.
