Third-country nationals are able to use the EES online tool to make the planning and calculating of their short stay in the EU member states easier.
The EES online tool is accessible online. It can be found on the European Union website:
Short stay is any stay that is not longer than 90 days in any period of 180 days. Short stay consists of every day of the stay in the last 180-day period.
The EES online tool is a tool to facilitate the determination of the length of a short stay. The final decision on short stay is the responsibility of authorised authorities.
If you want to manually check how long you can stay in the Schengen Area, you can use unofficial online tools, such as the Schengen calculator. Please note that these are unofficial calculations; the most accurate information can be obtained through the EES website.
