Around 25% of the five million Dutch nationals who work have planned a day off for June 14, when the Netherlands plays its debut World Cup football match against Denmark, says tourism research institute NRIT.
The match kicks off at 13.30 Dutch time.
According to Nos tv, Canon, Ernst & Young and Vodafone have already given workers time off to watch the match.
And football fans have set up a website wkkijken.nl to lobby companies into allowing staff to watch the match.
Around one third of the Dutch expect the Netherlands to be eliminated in the quarter finals, while 30% say the semis. And 14% of the Dutch think Oranje will take the title.
Brazil and Argentina can also count on a lot of support from the Dutch, followed by Germany.
