There are the four million Dutch who describe themselves as Roman Catholics but the young people are far more familiar with Islam than Christianity.
The Christian Ramadan
The Catholic charity Vastenaktie, which collects for the Third World across the Netherlands during the Lent period, is concerned that the Christian festival has become less important for the Dutch over the last generation.
"The image of the Catholic Lent must be polished. The fact that we use a Muslim term is related to the fact that Ramadan is a better-known concept among young people than Lent," said Vastenaktie Director, Martin Van der Kuil.
