netherlands round clock

Flag of the Netherlands. The flag of the Netherlands is a horizontal tricolour of red, white, and blue. It harks back to Charlemagne's time. Variants of the flag have been in use since 1572 and in 1937 the flag was officially formalized as the national flag of the Netherlands and of the Kingdom of the Netherlands. It is the oldest tricolor flag. The flag is customarily flown at government buildings and military bases in the Netherlands and abroad all year round. Private use is much rarer. Only on holidays such as Koninginnedag (Queen's Day) is there widespread private use. On Koninginnedag an orange pennant is added to the flag.
