The secret to a long-lasting marriage is not humour, patience, shared interests or an equal division of household chores. It's government intervention.
That, at least, is the hope of Norway's ruling Populist party, which is promoting date nights as a cure for flagging marriages in an attempt to reduce the country's divorce rate.
The new minister for children, equality and social inclusion, Solveig Horne, said the government needed to cut divorce rates - and that encouraging couples to try date nights was a good place to start: "It is important to find small pockets of time where parents can be lovers," she said.
Divorce rates are at 40 per cent in Norway, with those aged 40 to 44 most likely to split from their partners.
Since taking up her post this month, Horne has announced her intention to campaign for increased funding for family counselling to help prevent divorces.
"With state-run counselling offices, couples can learn more about how to be together before they have problems and talk things through when problems do arise," she said.
"It's not something the government can tell you to do; it's something that couples need to do on their own.
"In a busy life of work and family, the week can feel too short to attend to your relationship with your partner, so each couple needs to decide what sort of a date night they should have, whether it's a night at the movies or a walk together without the kids for a couple of hours."
Having been through a divorce herself, Horne is convinced that allocating time to a partner can have a huge impact on a relationship. "Maybe I didn't have success [in marriage] because we didn't have date nights," she said.
Horne's proposal has been cited by the country's media as further proof of the new government's centre-right bias, with many seeing parallels to a date night campaign started up by US conservative groups, the National Marriage Project.
Horne said she was more inspired by a 2010 romantic comedy starring Tina Fey and Steve Carell.
"I saw the movie Date Night where an American couple try to go out to keep their relationship alive," said Horne. "In the film, everything goes wrong, but I thought it was a good idea.
"My sister lives in the US and she told me that she and her husband have a weekly date night and it really works. Date night isn't really something that's done in Norway, but I think it could be a good way to keep marriages together."
