The Exhibition will last for the three-month maximum period authorised by the BIE, between Saturday 14th of June and Saturday 13th of September 2008. This period coincides with the summer when the days are long, and the nights can be enjoyed.

The Exhibition also coincides with tourism in Spain at its peak, which should ensure a steady flow of visitors. In summer the weather in Zaragoza is stable, hot and dry, ideal for open-air recreation and leisure activities. Summer festivities include the night of San Juan (24th of June), the Virgen del Carmen (16th of July), and the festivities of the 15th of August .

Each of them will have a special theme included in the Exhibition: the encounter of water and fire, women in accordance with the third principle of the Statement of Dublin and finally, the 15th of August will inaugurate a long weekend dedicated to "water games", with the River Ebro as its setting.
