'''''Koninkrijksdag''''' ({{langx|pap|Dia di Reino}}, {{langx|en|Kingdom Day}}) is the commemoration of the signing of the Charter for the Kingdom of the Netherlands on 15 December 1954 in Aruba, Curaçao, the Netherlands, and Sint Maarten. When 15 December falls on a Sunday, the commemoration takes place on Monday 16 December. Kingdom Day is, unlike ''Koningsdag'' ({{langx|en|King's Day}}), not an official national holiday, but government buildings are instructed to fly the flag of the Netherlands.<ref>{{Cite web |url=https://www.protocolbureau.com/2011/03/10/dutch-flag-protocol-nederlands-vlaggen-protocol-volgens-rijksoverheid-nl/ |title=Dutch Flag Protocol (Nederlands vlaggen protocol volgens rijksoverheid.nl) |date=2011-03-10 |website=Protocolbureau |access-date=2018-12-13 |df=dmy-all|language=nl}}</ref>
The charter was signed by Queen Juliana on 15 December 1954.<ref>{{Cite web |url=https://www.royal-house.nl/topics/history-of-the-kingdom-of-the-netherlands/history-of-the-monarchy |title=History of the monarchy |website=Royal House of the Netherlands |date=17 December 2014 |language=en-GB |access-date=2018-12-13 |df=dmy-all}}</ref> The charter deals with the relation between the Netherlands and the overseas territories, the Netherlands Antilles, Dutch New Guinea and Suriname. As of 2010, the charter governs the relationships between the Netherlands, Aruba (since 1986), Curaçao and Sint Maarten (since 2010).<ref name="kingdom-day-history">{{cite web |title=Kingdom Day |url=https://www.royal-house.nl/topics/history-of-the-kingdom-of-the-netherlands/kingdom-day |website=Royal House of the Netherlands |date=17 December 2014 |access-date=6 February 2024}}</ref>
Since 2005, the ''Koninkrijksconcert'' ({{langx|en|Kingdom Concert}}) is annually held on 15 December, to celebrate the relationship between the Netherlands, Aruba, Curaçao, and Sint Maarten.<ref name="kingdom-day-history" /> Before 2010, the concert celebrated the relationship with the Netherlands Antilles instead of Curaçao and Sint Maarten.
In 2008, ''Naturalisatiedag'' ({{langx|en|Naturalisation Day}}) in the Kingdom of the Netherlands was moved from 24 August, the day on which the Constitution of the Netherlands was signed, to 15 December, the day on which Queen Juliana signed the Charter for the Kingdom of the Netherlands. On Naturalisation Day, newly naturalized citizens officially receive their Dutch citizenship.<ref>{{cite web |title=Constitution of the Kingdom of the Netherlands of August 24, 1815 (consolidated version of 2017), Netherlands (Kingdom of the) |url=https://www.wipo.int/wipolex/en/legislation/details/17867 |website=WIPO Lex |access-date=6 February 2024}}</ref><ref name="kingdom-day-history" />
