I did some extensive research about 10 years ago and was astounded at what I found, it was exactly 14,000 days later to Friday August 10th 70 AD if you count from Sunday April 13th, 32 AD (17th day of Nisan) if you back up another 400 days its a Saturday and whats happening approx at that time is extremely interesting and explains why he started talking in Parables from that moment forward,
14400 days = 360 x 40
Just my conjecture of course
17th day of Nisan is also the calendar day when Noah came out of the Ark,
Interesting. Even though I like to emphasize the symbolic meaning of numbers in Revelation, I find it also interesting that sometimes numbers have more then one purpose/meaning in them as in the one you just spelled out in your calculations.
