The Visa Code allows certain flexibility in your travel plans. To enable you to adjust your travel plans at short notice if necessary, the validity of the Schengen visa is usually 15 days longer than the days of stay you have applied for. The permitted days of stay are not automatically extended by 15 days; only the validity of the visa is calculated more generously than applied for in case your trip is slightly delayed. The number of days of stay requested by you, supported by documentary evidence, and covered by travel health insurance is considered to be the maximum possible days before the expiry of which you must leave the Schengen area in an orderly manner, irrespective of the period of validity of the visa.
