Assessment question with calendar date

Turns out my method (above) does not work.

Using the example of a 75x75 grid - The x and y would both take 7 bits = Total of 14 bits.

However 75x75 = 5625 which would only take a total of 13 bits.

Can anyone explain this. Would technically 13 or 14 be correct?
How?

I’m linking here for posterity’s sake the continued discussion we had surrounding @glenn.crane’s example in another thread. It’s an interesting read that I hope others can benefit from!
