The answer to your question might sound silly to some, but I think this is because it deals with spiritual matters, and as such it seems strange to us. Including to me. My knowledge of these things is limited.
The elite who run our world don’t like the fact that all numbers belong to God and that he gives meaning to particular numbers. As Christians, we understand that the numbers 7, 3, 10, 12, 13, 17, 33, 153 and the others have particular meaning.
In the luciferian religion of the kabbal, because of their desire to take from God, they assign their own dark meaning to particular numbers.
We followers of Christ are taking everything back for God Almighty, the Lord of Heaven’s Armies. This includes numbers.
The number 17 appears, for example, significantly more than other numbers in Hollywood productions throughout the decades. In my opinion, this is the kabbal showing itself.
The date 10-7 is reduced to 17 because the 0 is considered to be nothing.
