Hey man..

Lighten up on disclosing personal info on dates.
Be cool, ok

69 is correct.
And 47 is correct.
I'll give you that much.
48 is the prime year though.
2017 is the year for that.

The Silver Gate is between Taurus, Orion, and Gemini.
That determines the birth date, when the Sun was in position, that of being centered between all 3.

Find that centered spot relating to the Silver Gate, and then the Birth Date is revealed.

Fathers Day is coming up here soon.
Hint...

And its not 666 either.
Its 616
