EventsEdit

January–MarchEdit

January 1 – The Philippines began reckoning Asian dates by hopping the International Date Line through skipping Tuesday, December 31, 1844. That time zone shift was a reform made by Governor–General Narciso Claveria on August 16, 1844, in order to align the local calendars in the country with the rest of Asia as trade interests with Imperial China, Dutch East Indies and neighboring countries increased, after Mexico became independent in 1821. The reform also applied to Caroline Islands, Guam, Marianas Islands, Marshall Islands, and Palau as part of the Captaincy General of the Philippines.<ref>{{#invoke:citation/CS1|citation
