Change visit schedule

Hi, sorry if I’m making repetitive or silly question, as this will be my first time to visit schengen area.

So my visa was approved from 31 March and at first I planned to go at that time, but due to some circumstances, I would like to postpone one day to 1 April.

Is it allowed to visit schengen at 1 April instead of 31 March? Will it be a trouble ?
