King’s Day (Koningsdag) is a national holiday in the Netherlands that is celebrated on April 27th (unless it falls on a Sunday, in which case it’s celebrated on April 26th). It marks the birthday of the reigning monarch of the Netherlands and is a day of vibrant festivities, nationwide parties, and a sea of orange-colored clothing and decorations.

Decorating houses is a significant aspect of King’s Day celebrations in the Netherlands. As part of the festive spirit, many people adorn their homes and surroundings with orange decorations and flags. The orange color represents the Dutch royal family, the House of Orange-Nassau, and is a symbol of national pride and unity.
