The scripture has the Gaps between the weeks as such -
"Know therefore and understand, That from the going forth of the command To restore and build Jerusalem Until Messiah the Prince, There shall be seven weeks and sixty-two weeks...
7 weeks
62 weeks
Then he shall confirm a covenant with many for one week; But in the middle of the week He shall bring an end to sacrifice and offering.
70th week
I am sorry you don't like or approve of the way the bible has arranged the time-frame of this prophecy.
17 So all the generations from Abraham to David are fourteen generations, from David until the captivity in Babylon are fourteen generations, and from the captivity in Babylon until the Christ are fourteen generations. Matthew 1:17
A Generation is 40 years.
Babylonian Captivity to Christ = 14 generations = 560 years
Time of Captivity = 70 years
560 -70 = 490 years
Gap between 7 weeks and 62 weeks = 40 years = 1 Generation
33 = Birth to “Palm Sundayâ€
490 - 40 = 450 years + 33 years “Birth†to Messiah the Prince 483 years = 69 weeks
[Messiah the Prince; Hosanna to the son of David]
