arrival date before visa date

[hpatel08]

hi,

I have applied for schengen visa through austrian embassy.
I believe i will get the visa for exact dates of my accomodation.

i have hotel booking 15 may onwards in vienna. Now i am getting a very good flight booking deal on 14th may. so i will reach vienna at 18.00 pm on 14th may.

My questions are :
1. Can i stay on vienna airport for 6 more hours as visa will start on 15th may.?
2. Will there be any problem in my home country and austria ?

Thanks in advance,
hp
