Change the start date of a pending worker

Hello all!

So, while we are trying to configure the Journey we are doing some tests with the pending worker's start dates. Our question is why even when we change the start date to an earlier one , the pending worker doesn't receive the email but only when the old date comes?

ex: I'm changing the start date from 17/5 to be 16/5. The pending worker doesn't receive the email of the Journey on 16/5 but on 17/5.

thank you in advance for your time

Maria☺️
