It is up to the airline to let you board the flight, just call them and ask what their policy is, personally I have been both rejected once when going to China and allowed once when going to Australia in the same situation and it has nothing to do with Schengen and all to do whether the airline requires your visa to be valid at the time of boarding or at the time of landing at your destination.
If they answer from the airline is no you need contacting the issuer of the visa and see if you can get a new one with the correct date for departure or change your flight one day later
