Interpret the meaning
" the full period of one hundred days." from the emancipation proclamation

I believe the answer is: once the proclamation has been declared, it will then be effectively done after one hundred days. After that, the emancipation proclamation will be effectively implemented.

There are two main purposes of the 100 days time period given by Lincoln.

The first one is to provide slave owners with enough time to think and adjust their operation if they choose to follow the emancipation proclamation. The second one is to give many people in confederates states the opportunity to abandon the confederate and join the union.
