The 70 sabbatical cycles are 490 years. (70 x 7 = 490) In 457 BC Artaxerxes gave the command to restore and rebuild Jerusalem. Ezra 6:14, 7:1-28. After 7 sabbatical cycles and 62 sabbatical cycles Jesus, the Messiah, the Anointed One came. ((7+62) x7=483) The 483 years ended in 27AD when the Holy Spirit anointed Jesus at His baptism.
The 70th sabbatical cycle ran from the fall of 27 AD to the fall of 34 AD.

The first coming of Christ occurred at the exact time predicted in Daniel’s prophecy.

The 70 Jubilee cycles of 3,431 years (70 x 49 +1 = 3,431) began in 1416 BC when the children of Israel entered Canaan. (See: When did the children of Israel enter Canaan?). The 3,431 years will end in 2016 AD, and Jesus will come the second time.
People are given until the end of seventy times seven sabbatical cycles (70 x 7 x 7 +1 = 3,431 years) to receive forgiveness from God. His forgiveness and His Righteousness will be offered until the end of the seventy "sevens" (70 Jubilees) in 2016.

Entering Canaan                                                                                                   Jesus comes again

The second coming of Jesus will occur at the exact time predicted in Daniel’s prophecy.  

Since Jesus died in 31 AD in the middle of the "seven" sabbatical cycle and "seven" Jubilee cycle, we can calculate exactly when each sabbatical cycle and each Jubilee cycle started and ended.
