There are 2 views regarding the Jubilee. View 1 holds that the Jubilee is every 50 years and view 2 is that the Jubilee is every 49 years (exclusive vs inclusive). The 2 views are not necessarily mutually exclusive. God left it ambiguous knowing that each interpretation would produce significance. The point here is that the proclamation of the Jubilee on Yom Kippur 2024 supports a 2017 - 2024 tribulation timeline. Having the Jubilee starting this month, Sept. 2015, will make for a pretty wimpy jubilee, IMHO!
