Many regard the build-up to Christmas and New Year as their favourite time of the year to shoot off some rockets at their neighbours or toss a few firecrackers at unsuspecting passers-by on the street.

But be careful this year because although you can start purchasing fireworks from December 15 (up until December 31), the new fireworks legislation dictates that they can only be lit between December 27 and January 1.

”It's still permitted to use fireworks on New Year's Eve and on January 1 until midnight,” the safety authorities Sikkerhedsstyrelsen wrote in a press release.

Six day window
Last year, firework lovers had all of December to purchase fireworks, and they were able to ignite their goods throughout December and part of January.

Many of the firework distributors find it odd that people can purchase their goods, but not use them unless it's in the six-day window leading up to New Year, but it helps that the new law eases rules concerning the storage of fireworks.
