The 20 lovebird couples flocked to the museum for the once in a lifetime opportunity to adorn their wedding certificate with the special date: 12-12-12.
Some of the couples had been planning their big day for months, but for others the decision came on the spur of the moment:

Lovebirds weren't the only Swedes who found something to celebrate.
Ellen Borgkvist from Höllviken in southern Sweden added another level of numerical symmetry to the occasion – Wednesday was her twelfth birthday.
She was planning to mark the special occasion with a family dinner.
