When did the count starts for schengen visa

[gm1orchid]

I have got a schengen visa from Hungarian embassy. Its a short stay visa for 90 days. The visa says the validity is from 14th August 2008 to 12th November 2008. There will be some slight changes in travel plans now.

I want to enter on 20th of August and return on 15th of November. Is it possible.

Does the validity starts from your date of entry or its valid only between the date mentioned in the visa.

[knowledgeable]

Valid only between the dates issued
